Resolver class for Ruby. It looks up AAAA record first, then A record. Ruby’s default resolver class (Resolv) looks up A record first, then AAAA record.
for example, assume that “ipv6.example.net” have these records on DNS,
ipv6.example.net. 80000 IN A 192.0.2.1 ipv6.example.net. 80000 IN AAAA 2001:db8::1
then ‘Resolv’ class (in the Ruby Standard Library) behaves:
require 'resolv' Resolv.getaddresses("ipv6.example.net") #=> ["192.0.2.1"] Resolv.getaddress("ipv6.example.net") #=> ["192.0.2.1", "2001:db8::1"]
If you want to lookup AAAA record prior to A record, install ‘resolv-ipv6favor’, then:
require 'resolv-ipv6favor' IPv6FavorResolv.getaddresses("ipv6.example.net") #=> ["2001:db8::1"] IPv6FavorResolv.getaddress("ipv6.example.net") #=> ["2001:db8::1", "192.0.2.1"]
-
Fork the project.
-
Make your feature addition or bug fix.
-
Add tests for it. This is important so I don’t break it in a future version unintentionally.
-
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
-
Send me a pull request. Bonus points for topic branches.
