Subject: Re: IPAddress: new IP manipulation library

Without having looked at your library, does it support IP ranges (i.e.
blocks of IP addresses that are contiguous but do not necessarily
exactly match a subnet boundary)?   Perhaps as a separate class?

Can one do this?

ip = IPAddress.new("10.0.0.1") ## No prefix specified... will it
assume /32 IPv4 host prefix?

Also, are there methods to determine if a network (or range, if
supported) contains another IP, network, or range?  Something like:

ip = IPAddress.new("10.0.0.1/32")
net = IPAddress.new("10.0.0.0/24")
puts "IP is contained by network" if net.contains?(ip) || ip.is_in?(net)

Wondering,
Aaron out.
