Network Information Systems Center October 1992
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 October 1992 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 Santa Cruz; see technical report UCSC-CRL-92-34 available
on host ftp.cse.ucsc.edu. The statistics below were generated by running
the collected host data through a number of utility programs.
