EXAMPLES

$ aggis 141.212 - 141.214
The range of nets from 141.212 to 141.214/16 can be represented by:

        141.212/15  (  2 nets:  141.212 - 141.213 )
        141.214/16  (  1 net:   141.214 )
$ aggis 141.212/18 - 216
The range of nets from 141.212.0 to 141.216.0/18 can be represented by:

        141.212/14  (  4 nets:  141.212 - 141.215 )
        141.216.0/18  (16384 hosts: 141.216.0.0 - 141.216.63.255 )
$ aggis 141.212/18
    141.212.0/18 is a subnet representing 1/4 of Class B network 141.212

                            Address Range 141.212.0.0 - 141.212.63.255

HISTORY

This version of aggis was ported to Perl 5 from the most recent version discoverable on Google, RCS version 2.7 from 1994/11/18, committed by Dale Johnson.

In oldten times, aggis was available from merit.edu:pub/nsfnet/cidr/aggis, which was long gone by the time of the Perl 5 port. There was, apparently, a manual page, but it appears to be lost to the ages.

At the time, it was possible to run Aggis through Merit's whois server:

whois -h prdb.merit.edu 'aggis 141.208.32/21'

but that host is also long gone.
