Exception on valid link-local ipv6 address

[Martyn Smith]

using a link-local ip address such as: fe80::302f:51e0:1313:f50d%5

causes an exception to be thrown whereas it's actually a valid address. The %5 is a reference to a scope id that the ipv6 address belongs to.

I'm a noob when it comes to git but I've got a workaround that seems to work by adding the lines below (with the +) to the RE_IPV6ADDRLIKE_COMPRESSED regex.

  RE_IPV6ADDRLIKE_COMPRESSED = %r{
    \A
    ( (?: (?: [\da-f]{1,4} : )* [\da-f]{1,4} )? )
    ::
    ( (?:
      ( (?: [\da-f]{1,4} : )* )
      (?:
        [\da-f]{1,4}
      |
        (\d+) \. (\d+) \. (\d+) \. (\d+)
+      |
+        [\da-f]{1,4} %[\d]+
      )
    )? )
    \z

Do you want me to walk you through the process of making a PR?

Actually the more I think about this, the less convinced I am this is the correct solution. It looks like the script avoids link-local addresses completely due to it being new functionality. I think the correct action at the moment is probably to filter the link-local addresses from being checked before they hit ipaddr.rb.

Thanks anyway.
