This looks fine to me, and we'll probably merge it, but I have a few concerns.
We normally try to avoid patching the standard library if we can help it. Especially like this, where a new dependency is being introduced. But perhaps MRI has this problem too when running in an IPv6 environment?
I don't have any IPv6 setup right now. Any chance you can try to reproduce with MRI?
Thanks for looking at the patch.
I could not reproduce the problem with MRI, see this comment. But anyway:
# grep nameserver /etc/resolv.conf nameserver 2001:1458:201:1100::5 nameserver 2001:1458:201:1100::5 # ruby -v ruby 2.0.0p648 (2015-12-16) [x86_64-linux] # time ruby -e "require 'resolv'; puts Resolv.getaddress 'web.cern.ch'" 184.108.40.206 real 0m0.083s user 0m0.061s sys 0m0.021s

I'm happy to perform other tests with MRI, just let me know :)
Do you see feasible to backport the patch to 1.7? That'd be awesome!
@headius I think if we can open up a new issue to figure out why we are different and close the issue around this PR we can land it. Then it will work as a workaround until we dig deeper. I would rather we release sooner than later...and hey it will not be our first modification to stdlib files :|
I would like to close the original report so we can display this is now working in the release in our notes (but we can link to it)
