Not necessarily. You can setup your own DNS server too. But, your hosting provider should forward DNS request to yours. --- | So... The webhost will take the domain \-- Not necessarily.

Why ? \-- There are thirteen primary root DNSs in the world, and all requests start from them. .com, .net, .info are called top-level domains [1]. So, if you have registered a new domain, your webhoster will need to inform the primary root DNSs about the new domain. It probably takes 48 hours for all the primary root DNSs to get to know the new domain. http://www.root-servers.org/ ...

They are responsible for it. If you have a LAN or a GNU/Linux system please try to setup forward, reverse DNS look-ups so you understand how DNS works. Also refer: http://tldp.org/HOWTO/DNS-HOWTO.html It helps to read, and read a lot. Atleast, in F/OSS you will have to inculcate the habit of reading. That is why I referred you DNS & Bind book from O'Reilly, which will help you in understanding root-servers, DNS, name resolution etc. and should answer all these questions.
