What are Nameservers?

A Name server is a software or specialized server on the Internet that handles queries or questions from your local computer, about the location of a domain name's various services.

Nameservers are part of DNS, which stands for “Domain Name System.” The DNS is a database that works like a phone book for computers: it converts a domain name, such as “www.example.com,” to a machine-readable IP address.

Whenever you type a domain into your browser,
Nameservers provide the IP address of the domain to your browser. If the DNS didn’t exist, you’d have to memorize strings of numbers for every website you wanted to visit.

Here’s how Nameserver work when you visit your own website, For Example  : Domain name is www.example.com

1.   First of all, you will type “www.example.com” into your browser.

2.   Your browser uses DNS to look up the nameservers for the Domain name (www.example.com).

3.   The nameservers ns1.yourhostdomain.com and ns2.yourhostdomain.com are retrieved.

4.   Your browser uses the nameservers to look up the IP address for www.example.com.

5.   Your browser gets the response: “192.000.00.000 ”

6.   Your browser sends a request 192.000.00.000 , including the specific page you’re trying to reach.

7.   The web server hosting your website sends the requested page to your browser.

 

This entire process take less than a second, so the majority of your visitors will never be aware of the nameservers you use for your site unless something goes wrong.

In many cases, you may not need to know or deal with the nameservers for your website. But if you register your name with a different company than you host your website with, you’ll need to set your nameservers for your domain to point to your web hosting account.

How to change Name Server of my Domain Name ?

Once you change the nameservers of your site, it can take up to 24- 48 hours to go into effect, though it typically takes about 4-8 hours in most cases. This delay is called “DNS propagation,” and exists because it takes time for each DNS server to update other servers around the world about the change.
