Rails - Feb 2009 - Problem with Socket.getaddrinfo inside controller or model

I am using Rails 2.2.2,
trying to get hostname by IP with code like

require ''socket''
Socket.getaddrinfo(''221.186.184.68'', nil, "AF_INET")

In the rails console it works well and gives me:

[["AF_INET", 0, "carbon.ruby-lang.org",
"221.186.184.68", 2, 2, 17],
["AF_INET", 0, "carbon.ruby-lang.org",
"221.186.184.68", 2, 1, 6]]

But, inside model or controller output different:

[["AF_INET", 0, "221.186.184.68",
"221.186.184.68", 2, 2, 17],
["AF_INET", 0, "221.186.184.68", "221.186.184.68",
2, 1, 6]]

Please help to fix and get hostname by ip inside model.

Hi,

There is a method in mongrel gem, mongrel.rb, Mongrel::HttpServer#run
which has a line:

BasicSocket.do_not_reverse_lookup=true

and it seems this changes the global state of the Socket class. So,
basically I did this:

BasicSocket.do_not_reverse_lookup=false
Socket.getaddrinfo(some_ip, nil, "AF_INET")
BasicSocket.do_not_reverse_lookup=true # In case nothing goes wrong
with mongrel :)

Quit annoying stuff, I found it almost accidently, doubt it is
somewhere documented.
