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
