Sorry brother if i sounded sneering!
I am very much thankful to all you guys in this forum.
I never meant to question you
Use "dig myveryuniquedomain.com +trace" to see which servers are being used to resolve your address. That might help you understand who it is that knows myveryuniquedomain.com equates to 100.101.102.103
But i am rather interested about how those servers (who resolves myveryuniquedomain.com to 100.101.102.103) know about this information.
In the domain registrator panel i gave my ns record as ns1.myveryuniquedomain.com. And not in any entry i was asked to enter the ipaddress of ns1.myveryuniquedomain.com. Then how come these nameservers know that ns1.myveryuniquedomain.com should resolve to 100.101.102.103?
Thank you for your help. Now reading more about glue records ..
