anyone has netrange -> cidr conversion script to share?
Does anyone here has a script (or perl procedure) for converting range of ips (i.e. 10.0.0.0 - 10.0.2.255) into cidr (i.e. result would be 10.0.0.0/23,10.0.2.0/24 from the example before). If not I'll do it, I'm just hoping somebody is already done something this for another project... Reply off the list. -- William Leibzon Elan Communications Inc. william@elan.net

netmask (available as a Debian package or a FreeBSD port) ~ % netmask -c 10.0.0.0:10.0.2.255 10.0.0.0/23 10.0.2.0/24

excellent Perl script called 'aggis' that used to be available from ftp.merit.edu ... I can't remember where I got it last. Since it's brief, I'm including it here for the sake of the archives. ... (well, I was going to, and saw that it was 557 lines, so I'll just post an url: http://www.darkuncle.net/aggis ) -- Scott Francis || darkuncle (at) darkuncle (dot) net illum oportet crescere me autem minui
