newbie dns question 1

[hasnofleas]

I have just leased a dedicated linux host. I have a ton of computer and Unix experience, but not so much in sys admin. I did not specify a name for the machine, and they gave me something like 'charliebrown01' as the machine name.

I have been reading up on DNS from many sources; none are exactly right for my situation. I have a pretty good idea how to set up the files on my own machine, though.

I understand that I set up a nameserver that will help me find other web sites from my machine. I give the name of the name server to my domain name registrar, associated with my domain names.

I know that, when somebody enters one of my domain names into their browser, their nameserver figures out if it knows how to find my site, and, if not, starts with the root domain, then the top level domain (TLD).

I have 2 questions:

1) how does the TLD know where to look for my domain names? Is it that the domain name registrar sends that info to the TLDs beforehand? Or does it just send my nameserver address, which thereafter communicates regularly with the TLD? what if I didn't tell the domain name registrar what nameserver to use for my other domains? would my nameserver communicate that info to the TLDs anyhow?

2) should I tell my dedicated host provider to change the name of the machine to something of the '

http://www.something.com'

format, or can I just use it as I have it now? I don't yet have the domain name that I would use for this, if necessary.

I actually do know a lot of stuff, and am learning the rest very quickly.

You domain registrar give the TLD people your domain name and name server. They put in an NS record for you name server. That's it.

If some one wants to contact one of your servers they get your DNS address from the TLD NS and ask your DNS for the info they need.

In your DNS you can put a CNAME record like

http://www IN

CNAME charliebrown01

so people can use

http://www.domain.nam
