I'm working on an iPad app, and I need to go from a URL such as www.mysite.com to the IP Address and port, 12.34.56.78   port 123 or so.

Has anyone done this?  I know this is a well defined (and most likely common) task, but I haven't made any headway figuring out how to do it. 

Worth noting I am still on iOS 3.2, we're not ready for iOS 4.0 yet.

Turns out the old-fashioned C function getaddrinfo() was all I needed.
