Matching The Domain Name

 Whenever a user requests for a particular URL, the DNS server converts the given URL into an IP address that is to be recognized by the internet. The search is then passed on to the internet to get the desired URL.

Operation of Root Server

The request then passes on to the DNS resolver, which is then used as a root server for the request. A root server is used to keep a track of the entire DNS server’s information. The root server remains the same all across the world.

Sending Queries To Root Server

The query then passes on to a root server. Various root servers are running across the globe. The location of these root servers is divided in a way to maintain a constant DNS server ratio. The DNS server is then sent on to the nearest root server available within your location.

As soon as your DNS request is passed on to these high-level servers, your DNS will be assigned an IP address for your domain server.

Domain’s Name Server

Your  DNS recursive resolver’s request is then accepted by the name of the domain. After this, the DNS server then verifies the IP address and the domain name. The verification result is then passed on to your DNS recursive resolver.
