Network Information Systems Center January 1994
SRI International Internet Domain Survey
The Domain Survey attempts to discover every host on the Internet by doing
a complete search of the Domain Name System. The latest results gathered
during late-January 1994 are listed. For more information see RFC 1296;
for more data see the pub/zone directory on ftp.nisc.sri.com.
