You really should be calling inet_addr first. The point is to avoid having to go out to the net to lookup a name that doesn''t need looking up.
Yes, you need to be connected to a network for gethostbyname to work. You need to have access to some sort of DNS server.
What, exactly, is it that doesn''t work, and what error code do you get? What is invalid, the name you''re putting in or the result you''re getting back? You really haven''t supplied the basic info about your problem.
