Just a side note (this part of the thread slipped past while I wasn't watching): gethostbyname() is going to work in "simple" environments, but you should really be using "getaddrinfo()" or "gethostinfo()", depending on your needs.

Good advice indeed. However, if you're already knee deep in CF code, you can use CFHost to get all of the IPv[46] addresses for a given DNS name. This allows you to handle IPv4 and IPv6 transparently, which is pretty cool.

The end result of the CFHost process is an CFArray of CFDatas, each of which contains a (struct sockaddr). Cool huh?
