- Network Information Systems Center January 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-January 1993 are listed. For more information see RFC 1296; for
- detailed data see the pub/zone directory on ftp.nisc.sri.com. This survey
- was done using the census program developed at the University of California
- on Santa Cruz; see technical report UCSC-CRL-92-34 on host ftp.cse.ucsc.edu.
- The statistics below were generated by running the collected host data
- through a number of utility programs.

- Frequently Asked Questions about the Domain Survey
-
- What'da all those domain names stand for?
- See pub/zone/iso-country-codes on ftp.nisc.sri.com.
-
- Why does the domain count go up and down?
- I don't know. Do you want to count them?
-
- Are all those hosts really on the Internet?
- You would have to ping them to find out. If they each took 100
- milliseconds to reply to a ping, you could find out in only 37 hours.
-
- How many users are on the Internet?
- Some people estimate around 10 per host (13 million people).
- If all of them were appropriately registered, the birthday-daemon
- would have to deliver 35,616 email messages each day.
-
- Where can I get more information?
- See the pub/zone directory on ftp.nisc.sri.com.
