+                SUMMARY OF SMALLBERG SURVEYS
+   
+This is a summary of the surveys of Telnet, FTP and Mail (SMTP)
+servers conducted by David Smallberg in December 1982 and January
+and February 1983 as reported in RFC 832-843, 845-846.  This memo
+extracts the number of hosts that accepted the connection to
+their server for each of Telnet, FTP, and SMTP, and compares it
+to the total host in the Internet (not counting TACs or ECHOS).
+
+One would not expect the percentage to reach 100, since some
+hosts will be down when the surveys are run, but many hosts are
+for special purposes and don't offer these services.  We estimate
+that 37 hosts or 11 percent are in this catagory and the highest
+percentage one could reasonably expect is 89.
