Apache Server URL Problem

[falcifer]

I'm trying to set up a server. All the things that I've found from searching tell me the same thing, and I've followed examples and tutorials, but it still won't work...

The situation here is that I have my server set up, and I can access it fine with the "http://localhost/", "http://127.0.0.1/" and with "http://my.ip.add.ress/"
However, I'm trying to set it up so that I can type a site name (e.g. "http://www.my-site.co.uk/").

I've edited the appropriate .conf files, and I can access it just fine on my own machine using the domain name, instead of the IP address. But it doesn't work on other machines.
I've been testing it on another computer in the house, and I can access it through the IP, but not by using the domain name.

What do I have to do to make it work?

Edit: I'm using Apache2 and I'm on openSUSE 10.2

Is that domain registered to you? If your domain is not registered with a Domain name provider like godaddy or something then a DNS lookup will not work as you domain is not associated with any DNS servers.

After doing some more looking, I found that out.

Is there no way for me to set up my own DNS server and assign my own domain to my IP?
Presumably that's what places like GoDaddy do?
