http://snippets.dzone.com/posts Sun, 18 May 2008 08:50:13 GMT DZone Snippets: NAT code http://snippets.dzone.com/posts/show/3947 Sometimes you just have to know what your external IP address is when there's a NAT between you and the rest of the world. Say you're in a DHCP environment that's constantly changing your IP, for example. This one-liner gives you your IP address as a string (in this case stored as "my_ip"). <br /> <br /><code> <br />my_ip = (require 'open-uri' ; open("http://myip.dk") { |f| /([0-9]{1,3}\.){3}[0-9]{1,3}/.match(f.read)[0].to_a[0] }) <br /></code> Wed, 02 May 2007 14:23:35 GMT http://snippets.dzone.com/posts/show/3947 ttmrichter (Michael T.
