It's the DNS that holds the zone data for your somedomain.com. To make that official as far as the Internet goes that's why they are asking where your records go... that is what nameservers house the records.

Anymore unless the company is sizable, I chose to use a world wide redundant DNS service (multiple DNS servers with redundance) to house records for a domain (e.g. DNSMadeEasy for example). But as I alluded to earlier you can certainly host your own DNS server(s) (they like for you to have more than one if possible).

When DNS queries are made, ulimately thigns work from the root server down to the tld's etc... and along those paths, your case .com knows who (what DNS servers) stands authoritative for somedomain.com.

With that said, you or anyone else can choose to point to a DNS that "says" it stands authoritative for records for whoever (somedomain.com, mil.gov, etc)... if if that is your DNS that your pointing to you'll get back whatever name to IP (etc) that you have defined there.

Hope that wasn't too confusing.

Maybe another example. The Whitepages is a phone book. I could print my own phone book and change anyone's phone number I want. But this doesn't work at large because chances are people are using the official whitepages and not my hacked up copy.

Hello,
this still looks confusing to me.

you mean to say the domain registrar will put the somedomain.com in the rootservers , so then it becomes official ?

i was thinking about the whois server.

does it play a role in making the domain official ?

am trying to visualize another thing:
for example, if we query the A records of a domain , the query would also do a whois to find what are the official nameservers. the whois records would then be updated by the domain registrar.

please let me have your views. thanks.
