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.
