Issue #13610 has been updated by herwin (Herwin W).


I think #11210 is the better solution here, since that has additional possibilities to get the formatting of the subnet mask (so you could easily output /24 instead of 255.255.255.0)

Feature #13610: IPAddr doesn't provide helpful methods to get the subnet or IP address

----------------------------------------
I've implemented it myself using some "wild" code around the .inspect or default return from an IPAddr object from ipadr.rb

It would be nice to, once having loaded an IP range, to then be able to get its subnet, its IP and its CIDR.

I've created a PR: https://github.com/ruby/ruby/pull/1636 (although it's failing, not entirely sure why as Travis works fine on localhost!).
