> 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.
