Network Information Systems Center July 1993
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 mid-July 1993 are listed. For more information see RFC 1296; for
more info see the pub/zone directory on ftp.nisc.sri.com.

Frequently Asked Questions about the Domain Survey
What do all those domain names stand for?
See pub/zone/iso-country-codes on ftp.nisc.sri.com.
Why do only 26% of the advertised hosts answer a ping?
Many advertised hosts are behind firewalls that only allow email
to get through. Technically, they would not be considered hosts
that are directly on the Internet. Smaller hosts such as PCs might
be turned off when they are not in use. Also, some pings are probably
lost due to links being down, and/or problems with the pinging process.
Where can I get more information?
See the pub/zone directory on ftp.nisc.sri.com.
