Ruby net-dns reverse lookups
原标题:

I am trying to get reverse DNS lookups working with the net-dns gem for ruby.

From the rdoc

res = Net::DNS::Resolver.new
ip = IPAddr.new("172.16.100.2")
packet = res.search(ip)
packet = res.search("192.168.10.254")

should work but I m getting

ArgumentError: invalid address

for the last two lines.

This happens using a custom gem built from head of github source or the latest released version from

gem install net-dns

This is a known issue. It should be fixed soon.
