Well, this domains just dont have a reverse DNS entry. Thats not a ruby 
problem, but a DNS problem. 

and this is not really broken. it is not mandatory for an IP address to have a 
mapping to a domain naime IIRC. 

and even if it exists it could be totally different from the original domain, 
as you can map lots of domains to an IP address.
