I am total new to this. I have a domain name which was hosted by a webhost. For example, my domain name is www.somename.com and xxxhosting is hosting it on an IP addrss which is 56.4545.399343.xxx.

Now that I have my own dedicated server, I want to host my website there and want ppl to go ther via my domain name "www.somename.com".

Now, how do I map my dedicated server IP address to the domain name?

Name server?!!! [what is that? how does it work?]
DNS setup??!!! [Whart is that?]

I have followed tutorials in setting up my "LAMP" RHL9 server.

I was looking for a tutorial for a n00b like me to set up the domain name with my dedicated server IP address.

Please help.
