Apologies, you're right. That was a stupid mistake to make :) However, I'm still getting an invalid address: ruby-1.9.3-p0 :004 > IPAddr.new('FF32:00FF:A12:34FF:FE56:7890::/96', Socket::AF_INET6) ArgumentError: invalid address from /Users/jnh/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/ipaddr.rb:496:in `rescue in initialize' from /Users/jnh/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/ipaddr.rb:493:in `initialize' from (irb):4:in `new' from (irb):4 from /Users/jnh/.rvm/rubies/ruby-1.9.3-p0/bin/irb:16:in `

' I have tested on both 1.9.2 and 1.8.7: ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin11.1.0] ruby 1.8.7 (2011-06-30 patchlevel 352) [i686-darwin11.2.0] Looking over #valid_v6 it appears that it contains a number of invalid regular expressions (IPv4 compatible IPv6 addressing was deprecated by RFC4291 in 2006 for example). I would suggest that all the regular expressions are removed and the operating systems inet_pton() call is used to validate it instead. -- http://redmine.ruby-lang.org
