问题
I want to programmatically obtain the IP address of a computer on the LAN, given its hostname.
I know from the command line i can do this by ping < hostname >, but how can i do this programmatically in objective-c? Thanks.

Ok, gethostbyname() always works when trying to find the ip address given a hostname, as long as the hostname of the computer you ae trying to access has its name registered in a DNS Server. All comments and answers above were useful.
