netmask

[Hamish Moffatt <hamish@debian.org>]

Is a netmask of 255.255.255.128 (ie half a class C) 25 bits of
address, ie a /28 designator for tools that use that form of netmask?
I think it should but have never really known the rules for this.
I figure 32 bits is one host (255.255.255.255), 24 bits is
a class C (255.255.255.0); half of a class C is one less bit used
within the network, ie 25.

ipfwadm likes this form of netmask.

thanks.
