Introduction + + This document describes an Internet domain name mapping for version + 1.0 of the Extensible Provisioning Protocol (EPP). This mapping is + specified using the Extensible Markup Language (XML) 1.0 as described + in [W3C.REC-xml-20040204] and XML Schema notation as described in + [W3C.REC-xmlschema-1-20041028] and [W3C.REC-xmlschema-2-20041028]. + This document obsoletes RFC 3731 [RFC3731]. + + [RFC4930] provides a complete description of EPP command and response + structures. A thorough understanding of the base protocol + specification is necessary to understand the mapping described in + this document. + + XML is case sensitive. Unless stated otherwise, XML specifications + and examples provided in this document MUST be interpreted in the + character case presented to develop a conforming implementation. + +1.1. Relationship of Domain Objects and Host Objects + + The EPP mapping for host objects is described in [RFC4932]. This + document assumes that domain name objects have a superordinate + relationship to subordinate host name objects. For example, domain + name "example.com" has a superordinate relationship to host name + "ns1.example.com". EPP actions (such as object transfers) that do + not preserve this relationship MUST be explicitly disallowed. + + A host name object can be created in a repository for which no + superordinate domain name object exists. For example, host name + "ns1.example.com" can be created in the ".example" repository so that + DNS domains in ".example" can be delegated to the host. Such hosts + are described as "external" hosts in this specification since the + name of the host does not belong to the name space of the repository + in which the host is being used for delegation purposes. + + Whether a host is external or internal relates to the repository in + which the host is being used for delegation purposes. Whether or not + an internal host is subordinate relates to a domain within the + repository. For example, host ns1.example1.com is a subordinate host + of domain example1.com, but it is not a subordinate host of domain + example2.com. ns1.example1.com can be used as a name server for + example2.com. In this case, ns1.example1.com MUST be treated as an + internal host, subject to the rules governing operations on + subordinate hosts within the same repository. + + Name server hosts for domain delegation can be specified as either + references to existing host objects or as domain attributes that + describe a host machine. A server operator MUST use one name server + + + +Hollenbeck Standards Track [Page 3] + +RFC 4931 EPP Domain Name Mapping May 2007 + + + specification form consistently. A server operator that announces + support for host objects in an EPP greeting MUST NOT allow domain + attributes to describe a name server host machine. A server operator + that does not announce support for host objects MUST allow domain + attributes to describe a name server host machine. When domain + attributes are used to describe a name server host machine, IP + addresses SHOULD be required only as needed to generate DNS glue + records. + + Name servers are specified within a <domain:ns> element. This + element MUST contain one or more <domain:hostObj> elements or one or + more <domain:hostAttr> elements. A <domain:hostObj> element contains + the fully qualified name of a known name server host object. A + <domain:hostAttr> element contains the following child elements: + + - A <domain:hostName> element that contains the fully qualified name + of a host. + + - Zero or more OPTIONAL <domain:hostAddr> elements that contain the + IP addresses to be associated with the host. Each element MAY + contain an "ip" attribute to identify the IP address format. + Attribute value "v4" is used to note IPv4 address format. + Attribute value "v6" is used to note IPv6 address format. If the + "ip" attribute is not specified, "v4" is the default attribute + value. IP address syntax requirements are described in Section + 2.5 of the EPP host mapping [RFC4932]. + + Example host object name server elements for domain example.com: + + <domain:ns> + <domain:hostObj>ns1.example.com</domain:hostObj> + <domain:hostObj>ns1.example.net</domain:hostObj> + </domain:ns> + + Example host attribute name server elements for domain example.com: + + <domain:ns> + <domain:hostAttr> + <domain:hostName>ns1.example.com</domain:hostName> + <domain:hostAddr + ip="v4">192.0.2.2</domain:hostAddr> + <domain:hostAddr + ip="v6">1080:0:0:0:8:800:200C:417A</domain:hostAddr> + </domain:hostAttr> + <domain:hostAttr> + <domain:hostName>ns1.example.net</domain:hostName> + </domain:hostAttr> + </domain:ns> + + + +Hollenbeck Standards Track [Page 4] + +RFC 4931 EPP Domain Name Mapping May 2007 + + +1.2. Conventions Used in This Document + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in [RFC2119]. + + In examples, "C:" represents lines sent by a protocol client and "S:" + represents lines returned by a protocol server. Indentation and + white space in examples are provided only to illustrate element + relationships and are not a REQUIRED feature of this protocol. + +2. Object Attributes + + An EPP domain object has attributes and associated values that can be + viewed and modified by the sponsoring client or the server. This + section describes each attribute type in detail. The formal syntax + for the attribute values described here can be found in the "Formal + Syntax" section of this document and in the appropriate normative + references. + +2.1. Domain and Host Names + + The syntax for domain and host names described in this document MUST + conform to [RFC0952] as updated by [RFC1123]. At the time of this + writing, RFC 3490 [RFC3490] describes a standard to use certain ASCII + name labels to represent non-ASCII name labels. These conformance + requirements might change as a result of progressing work in + developing standards for internationalized domain names. A server + MAY restrict allowable domain names to a particular top-level domain, + second-level domain, or other domain for which the server is + authoritative. The trailing dot required when these names are stored + in a DNS zone is implicit and MUST NOT be provided when exchanging + host and domain names. + +2.2. Contact and Client Identifiers + + All EPP contacts are identified by a server-unique identifier. + Contact identifiers are character strings with a specified minimum + length, a specified maximum length, and a specified format. Contact + identifiers use the "clIDType" client identifier syntax described in + [RFC4930]. + +2.3. Status Values + + A domain object MUST always have at least one associated status + value. Status values can be set only by the client that sponsors a + domain object and by the server on which the object resides. A + client can change the status of a domain object using the EPP + + + +Hollenbeck Standards Track [Page 5] + +RFC 4931 EPP Domain Name Mapping May 2007 + + + <update> command. Each status value MAY be accompanied by a string + of human-readable text that describes the rationale for the status + applied to the object. + + A client MUST NOT alter status values set by the server. A server + MAY alter or override status values set by a client subject to local + server policies. The status of an object MAY change as a result of + either a client-initiated transform command or an action performed by + a server operator. + + Status values that can be added or removed by a client are prefixed + with "client". Corresponding status values that can be added or + removed by a server are prefixed with "server". Status values that + do not begin with either "client" or "server" are server-managed. + + Status Value Descriptions: + + - clientDeleteProhibited, serverDeleteProhibited + + Requests to delete the object MUST be rejected. + + - clientHold, serverHold + + DNS delegation information MUST NOT be published for the object. + + - clientRenewProhibited, serverRenewProhibited + + Requests to renew the object MUST be rejected. + + - clientTransferProhibited, serverTransferProhibited + + Requests to transfer the object MUST be rejected. + + - clientUpdateProhibited, serverUpdateProhibited + + Requests to update the object (other than to remove this status) + MUST be rejected. + + - inactive + + Delegation information has not been associated with the object. + + - ok + + This is the normal status value for an object that has no pending + operations or prohibitions. This value is set and removed by the + server as other status values are added or removed. + + + + +Hollenbeck Standards Track [Page 6] + +RFC 4931 EPP Domain Name Mapping May 2007 + + + - pendingCreate, pendingDelete, pendingRenew, pendingTransfer, + pendingUpdate + + A transform command has been processed for the object, but the + action has not been completed by the server. Server operators can + delay action completion for a variety of reasons, such as to allow + for human review or third-party action. A transform command that + is processed, but whose requested action is pending, is noted with + response code 1001. + + When the requested action has been completed, the pendingCreate, + pendingDelete, pendingRenew, pendingTransfer, or pendingUpdate status + value MUST be removed. All clients involved in the transaction MUST + be notified using a service message that the action has been + completed and that the status of the object has changed. + + "ok" status MUST NOT be combined with any other status. + + "pendingDelete" status MUST NOT be combined with either + "clientDeleteProhibited" or "serverDeleteProhibited" status. + + "pendingRenew" status MUST NOT be combined with either + "clientRenewProhibited" or "serverRenewProhibited" status. + + "pendingTransfer" status MUST NOT be combined with either + "clientTransferProhibited" or "serverTransferProhibited" status. + + "pendingUpdate" status MUST NOT be combined with either + "clientUpdateProhibited" or "serverUpdateProhibited" status. + + The pendingCreate, pendingDelete, pendingRenew, pendingTransfer, and + pendingUpdate status values MUST NOT be combined with each other. + + Other status combinations not expressly prohibited MAY be used. + +2.4. Dates and Times + + Date and time attribute values MUST be represented in Universal + Coordinated Time (UTC) using the Gregorian calendar. The extended + date-time form using upper case "T" and "Z" characters defined in + [W3C.REC-xmlschema-2-20041028] MUST be used to represent date-time + values as XML Schema does not support truncated date-time forms or + lower case "T" and "Z" characters. + + + + + + + + +Hollenbeck Standards Track [Page 7] + +RFC 4931 EPP Domain Name Mapping May 2007 + + +2.5. Validity Periods + + A domain name object MAY have a specified validity period. If server + policy supports domain object validity periods, the validity period + is defined when a domain object is created, and it MAY be extended by + the EPP <renew> or <transfer> commands. As a matter of server + policy, this specification does not define actions to be taken upon + expiration of a domain object's validity period. + + Validity periods are measured in years or months with the appropriate + units specified using the "unit" attribute. Valid values for the + "unit" attribute are "y" for years and "m" for months. The minimum + allowable period value is one (1). The maximum allowable value is + ninety-nine decimal (99). A server MAY support a lower maximum + value. + +2.6. Authorization Information + + Authorization information is associated with domain objects to + facilitate transfer operations. Authorization information is + assigned when a domain object is created, and it might be updated in + the future. This specification describes password-based + authorization information, though other mechanisms are possible. + +2.7. Other DNS Resource Record Attributes + + While the DNS allows many resource record types to be associated with + a domain, this mapping only explicitly specifies elements that + describe resource records used for domain delegation and resolution. + Facilities to provision other domain-related resource record types + can be developed by extending this mapping. + + The provisioning method described in this mapping separates discrete + data elements by data type. This method of data definition allows + XML Schema processors to perform basic syntax validation tasks, + reducing ambiguity and the amount of parsing and syntax-checking work + required of protocol processors. Provisioning and extension methods + that aggregate data into opaque strings are possible, but such + methods SHOULD NOT be used because they impose additional parsing, + interpretation, and validation requirements on protocol processors. + + + + + + + + + + + +Hollenbeck Standards Track [Page 8] + +RFC 4931 EPP Domain Name Mapping May 2007 + + +3. EPP Command Mapping + + A detailed description of the EPP syntax and semantics can be found + in [RFC4930]. The command mappings described here are specifically + for use in provisioning and managing Internet domain names via EPP. + +3.1. EPP Query Commands + + EPP provides three commands to retrieve domain information: <check> + to determine if a domain object can be provisioned within a + repository, <info> to retrieve detailed information associated with a + domain object, and <transfer> to retrieve domain object transfer + status information. + +3.1.1. EPP <check> Command + + The EPP <check> command is used to determine if an object can be + provisioned within a repository. It provides a hint that allows a + client to anticipate the success or failure of provisioning an object + using the <create> command as object provisioning requirements are + ultimately a matter of server policy. + + In addition to the standard EPP command elements, the <check> command + MUST contain a <domain:check> element that identifies the domain + namespace. The <domain:check> element contains the following child + elements: + + - One or more <domain:name> elements that contain the fully + qualified names of the domain objects to be queried. + + Example <check> command: + + C:<?xml version="1.0" encoding="UTF-8" standalone="no"?> + C:<epp xmlns="urn:ietf:params:xml:ns:epp-1.0"> + C: <command> + C: <check> + C: <domain:check + C: xmlns:domain="urn:ietf:params:xml:ns:domain-1.0"> + C: <domain:name>example.com</domain:name> + C: <domain:name>example.net</domain:name> + C: <domain:name>example.org</domain:name> + C: </domain:check> + C: </check> + C: <clTRID>ABC-12345</clTRID> + C: </command> + C:</epp> + + + + + +Hollenbeck Standards Track [Page 9] + +RFC 4931 EPP Domain Name Mapping May 2007 + + + When a <check> command has been processed successfully, the EPP + <resData> element MUST contain a child <domain:chkData> element that + identifies the domain namespace. The <domain:chkData> element + contains one or more <domain:cd> elements that contain the following + child elements: + + - A <domain:name> element that contains the fully qualified name of + the queried domain object. This element MUST contain an "avail" + attribute whose value indicates object availability (can it be + provisioned or not) at the moment the <check> command was + completed. A value of "1" or "true" means that the object can be + provisioned. A value of "0" or "false" means that the object can + not be provisioned. + + - An OPTIONAL <domain:reason> element that MAY be provided when an + object cannot be provisioned. If present, this element contains + server-specific text to help explain why the object cannot be + provisioned. This text MUST be represented in the response + language previously negotiated with the client; an OPTIONAL "lang" + attribute MAY be present to identify the language if the + negotiated value is something other than the default value of "en" + (English). + + Example <check> response: + + S:<?xml version="1.0" encoding="UTF-8" standalone="no"?> + S:<epp xmlns="urn:ietf:params:xml:ns:epp-1.0"> + S: <response> + S: <result code="1000"> + S: <msg>Command completed successfully</msg> + S: </result> + S: <resData> + S: <domain:chkData + S: xmlns:domain="urn:ietf:params:xml:ns:domain-1.0"> + S: <domain:cd> + S: <domain:name avail="1">example.com</domain:name> + S: </domain:cd> + S: <domain:cd> + S: <domain:name avail="0">example.net</domain:name> + S: <domain:reason>In use</domain:reason> + S: </domain:cd> + S: <domain:cd> + S: <domain:name avail="1">example.org</domain:name> + S: </domain:cd> + S: </domain:chkData> + S: </resData> + S: <trID> + S: <clTRID>ABC-12345</clTRID> + + + +Hollenbeck Standards Track [Page 10] + +RFC 4931 EPP Domain Name Mapping May 2007 + + + S: <svTRID>54322-XYZ</svTRID> + S: </trID> + S: </response> + S:</epp> + + An EPP error response MUST be returned if a <check> command cannot be + processed for any reason. + +3.1.2. EPP <info> Command + + The EPP <info> command is used to retrieve information associated + with a domain object. The response to this command MAY vary + depending on the identity of the querying client, use of + authorization information, and server policy towards unauthorized + clients. If the querying client is the sponsoring client, all + available information MUST be returned. If the querying client is + not the sponsoring client, but the client provides valid + authorization information, all available information MUST be + returned. If the querying client is not the sponsoring client, and + the client does not provide valid authorization information, server + policy determines which OPTIONAL elements are returned. + + In addition to the standard EPP command elements, the <info> command + MUST contain a <domain:info> element that identifies the domain + namespace. The <domain:info> element contains the following child + elements: + + - A <domain:name> element that contains the fully qualified name of + the domain object to be queried. An OPTIONAL "hosts" attribute is + available to control return of information describing hosts + related to the domain object. A value of "all" (the default, + which MAY be absent) returns information describing both + subordinate and delegated hosts. A value of "del" returns + information describing only delegated hosts. A value of "sub" + returns information describing only subordinate hosts. A value of + "none" returns no information describing delegated or subordinate + hosts. + + - An OPTIONAL <domain:authInfo> element that contains authorization + information associated with the domain object or authorization + information associated with the domain object's registrant or + associated contacts. An OPTIONAL "roid" attribute MUST be used to + identify the registrant or contact object if and only if the given + authInfo is associated with a registrant or contact object, and + not the domain object itself. If this element is not provided or + if the authorization information is invalid, server policy + determines if the command is rejected or if response information + will be returned to the client. + + + +Hollenbeck Standards Track [Page 11] + +RFC 4931 EPP Domain Name Mapping May 2007 + + + Example <info> command without authorization information: + + C:<?xml version="1.0" encoding="UTF-8" standalone="no"?> + C:<epp xmlns="urn:ietf:params:xml:ns:epp-1.0"> + C: <command> + C: <info> + C: <domain:info + C: xmlns:domain="urn:ietf:params:xml:ns:domain-1.0"> + C: <domain:name hosts="all">example.com</domain:name> + C: </domain:info> + C: </info> + C: <clTRID>ABC-12345</clTRID> + C: </command> + C:</epp> + + Example <info> command with authorization information: + + C:<?xml version="1.0" encoding="UTF-8" standalone="no"?> + C:<epp xmlns="urn:ietf:params:xml:ns:epp-1.0"> + C: <command> + C: <info> + C: <domain:info + C: xmlns:domain="urn:ietf:params:xml:ns:domain-1.0"> + C: <domain:name hosts="all">example.com</domain:name> + C: <domain:authInfo> + C: <domain:pw>2fooBAR</domain:pw> + C: </domain:authInfo> + C: </domain:info> + C: </info> + C: <clTRID>ABC-12345</clTRID> + C: </command> + C:</epp> + + When an <info> command has been processed successfully, the EPP + <resData> element MUST contain a child <domain:infData> element that + identifies the domain namespace.

Internationalization Considerations + + EPP is represented in XML, which provides native support for encoding + information using the Unicode character set and its more compact + representations including UTF-8. Conformant XML processors recognize + both UTF-8 and UTF-16 [RFC2781]. Though XML includes provisions to + identify and use other character encodings through use of an + "encoding" attribute in an <?xml?> declaration, use of UTF-8 is + RECOMMENDED in environments where parser encoding support + incompatibility exists. + + All date-time values presented via EPP MUST be expressed in Universal + Coordinated Time using the Gregorian calendar. XML Schema allows use + of time zone identifiers to indicate offsets from the zero meridian, + but this option MUST NOT be used with EPP. The extended date-time + form using upper case "T" and "Z" characters defined in + [W3C.REC-xmlschema-2-20041028] MUST be used to represent date-time + values as XML Schema does not support truncated date-time forms or + lower case "T" and "Z" characters. + + This document requires domain and host name syntax as specified in + [RFC0952] as updated by [RFC1123]. At the time of this writing, RFC + 3490 [RFC3490] describes a standard to use certain ASCII name labels + to represent non-ASCII name labels. These conformance requirements + might change as a result of progressing work in developing standards + for internationalized domain names. + +6. IANA Considerations + + This document uses URNs to describe XML namespaces and XML schemas + conforming to a registry mechanism described in [RFC3688]. Two URI + assignments have been registered by the IANA. + + Registration request for the domain namespace: + + URI: urn:ietf:params:xml:ns:domain-1.0 + + + + + +Hollenbeck Standards Track [Page 40] + +RFC 4931 EPP Domain Name Mapping May 2007 + + + Registrant Contact: See the "Author's Address" section of this + document. + + XML: None.

Security Considerations + + Authorization information as described in section 2.6 is REQUIRED to + create a domain object. This information is used in some query and + transfer operations as an additional means of determining client + authorization to perform the command. Failure to protect + authorization information from inadvertent disclosure can result in + unauthorized transfer operations and unauthorized information + release. Both client and server MUST ensure that authorization + information is stored and exchanged with high-grade encryption + mechanisms to provide privacy services. + + The object mapping described in this document does not provide any + other security services or introduce any additional considerations + beyond those described by [RFC4930] and protocol layers used by EPP. + +8.
