Hinden +Request for Comments: 2732 Nokia +Category: Standards Track B. Carpenter + IBM + L. Masinter + AT&T + December 1999 + + + Format for Literal IPv6 Addresses in URL's + +Status of this Memo + + This document specifies an Internet standards track protocol for the + Internet community, and requests discussion and suggestions for + improvements. Please refer to the current edition of the "Internet + Official Protocol Standards" (STD 1) for the standardization state + and status of this protocol. Distribution of this memo is unlimited. + +Copyright Notice + + Copyright (C) The Internet Society (1999). All Rights Reserved. + +Abstract + + This document defines the format for literal IPv6 Addresses in URL's + for implementation in World Wide Web browsers. This format has been + implemented in the IPv6 versions of several widely deployed browsers + including Microsoft Internet Explorer, Mozilla, and Lynx. It is also + intended to be used in the IPv6 version of the service location + protocol. + + This document incudes an update to the generic syntax for Uniform + Resource Identifiers defined in RFC 2396 [URL]. It defines a syntax + for IPv6 addresses and allows the use of "[" and "]" within a URI + explicitly for this reserved purpose. + +1. Introduction + + The textual representation defined for literal IPv6 addresses in + [ARCH] is not directly compatible with URL's. Both use ":" and "." + characters as delimiters. This document defines the format for + literal IPv6 Addresses in URL's for implementation in World Wide Web + browsers. The goal is to have a format that allows easy "cut" and + "paste" operations with a minimum of editing of the literal address. + + + + + + +Hinden, et al. Standards Track [Page 1] + +RFC 2732 IPv6 Literal Addresses in URL's December 1999 + + + The format defined in this document has been implemented in the IPv6 + versions of several widely deployed browsers including Microsoft + Internet Explorer, Mozilla, and Lynx. It is also intended to be used + in the IPv6 version of the service location protocol. + +1.1 Requirements + + The keywords MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD, + SHOULD NOT, RECOMMENDED, MAY, and OPTIONAL, if and where they appear + in this document, are to be interpreted as described in [KEYWORDS]. + + World Wide Web browsers SHOULD implement the format of IPv6 literals + in URL's defined in this document. Other types of applications and + protocols that use URL's MAY use this format. + +2. Literal IPv6 Address Format in URL's Syntax + + To use a literal IPv6 address in a URL, the literal address should be + enclosed in "[" and "]" characters. For example the following + literal IPv6 addresses: + + FEDC:BA98:7654:3210:FEDC:BA98:7654:3210 + 1080:0:0:0:8:800:200C:4171 + 3ffe:2a00:100:7031::1 + 1080::8:800:200C:417A + ::192.9.5.5 + ::FFFF:129.144.52.38 + 2010:836B:4179::836B:4179 + + would be represented as in the following example URLs: + + http://[FEDC:BA98:7654:3210:FEDC:BA98:7654:3210]:80/index.html + http://[1080:0:0:0:8:800:200C:417A]/index.html + http://[3ffe:2a00:100:7031::1] + http://[1080::8:800:200C:417A]/foo + http://[::192.9.5.5]/ipng + http://[::FFFF:129.144.52.38]:80/index.html + http://[2010:836B:4179::836B:4179] + +3. Changes to RFC 2396 + + This document updates the generic syntax for Uniform Resource + Identifiers defined in RFC 2396 [URL]. It defines a syntax for IPv6 + addresses and allows the use of "[" and "]" within a URI explicitly + for this reserved purpose. + + + + + + +Hinden, et al. Standards Track [Page 2] + +RFC 2732 IPv6 Literal Addresses in URL's December 1999 + + + The following changes to the syntax in RFC 2396 are made: + (1) change the 'host' non-terminal to add an IPv6 option: + + host = hostname | IPv4address | IPv6reference + ipv6reference = "[" IPv6address "]" + + where IPv6address is defined as in RFC2373 [ARCH]. + + (2) Replace the definition of 'IPv4address' with that of RFC 2373, as + it correctly defines an IPv4address as consisting of at most three + decimal digits per segment. + + (3) Add "[" and "]" to the set of 'reserved' characters: + + reserved = ";" | "/" | "?" | ":" | "@" | "&" | "=" | "+" | + "$" | "," | "[" | "]" + + and remove them from the 'unwise' set: + + unwise = "{" | "}" | "|" | "\" | "^" | "`" + +4. Security Considerations + + The use of this approach to represent literal IPv6 addresses in URL's + does not introduce any known new security concerns. + +5. IANA Considerations + + None. + + + + + + + + + + + + + + + + + + + + + + +Hinden, et al. Standards Track [Page 3] + +RFC 2732 IPv6 Literal Addresses in URL's December 1999 + + +6.
