I'm a developer and I'm having trouble setting up some hosting, and I hope you guys can help me out.
I've got a domain I'm setting up for a friend. URLs work fine when I use the short form, like
http://example.com. That is, the pages render properly and I get HTTP/200 responses. When I try
http://www.example.com, however, I get a HTTP/502 error. Pinging it gives me,
Ping request could not find host www.example.com. Please check the name and try again.
I'm stumped, because I don't know enough terminology to formulate a good keyword search. Can anyone give me some info on what I might need to do to set up some kind of alias so that the standard
www. form will work? I don't know whether to talk to my registrar or my hosting company, what to ask them for, or where to look in the various control panels.
Any help at all — even just naming the different pieces — would be helpful. I don't know my TLDs from my domain aliases from my CNAMEs.
