Question

Illustrate the complete procedure to map a domain name to an IP address through an example

Answer 1

Every computer on the internet is identified by an Internet protocol (IP). IP is a set of numbers that can be mapped to letters to make it easy for the human mind. The lettered version of the IP is called the domain name. The mapping domain name to IP address is done by the Domain Name Server (DNS).

A user types the domain name into the browser, such as google.com.

The browser sends google.com to the Internet Service Provider as a DNS request.

The ISP checks if it can resolve the IP before forwarding the request to other providers. 

The DNS maps the domain name (goole.com) to the located IP address (142.250.72.142).

The IP address is sent back to the browser, which can now communicate with the server directly.

The user is abstracted from viewing google.com as 142.250.72.142.
