What is Domain Name Server(DNS)

Domain Name Server(System) helps the viewers connects to the Website using domain names instead of IP address. Every time a user requests a page from a website, DNS will translate the requested URL into IP address and connecting to the server. The main function of the nameserver is to store the “zone file” of the domain, where all domain information is kept (registration data, host records, etc.) 

Nameservers are a fundamental part of Domain Name System. A nameserver is a server which controls the DNS for a domain and they allow to use domains instead of IP addresses. 

Nameserver allows you to decide which hosting company controls your web space and email. All domain registrars should provide you with the ability to change at least two nameserver entries on your domain name, and hosting companies should offer you at least two nameservers to point to.

Example
ns0.meinfoway.com
ns1.meinfoway.com

After you register a new domain name or when you update the DNS servers on your domain name, it usually takes about 24-72 hours for the domain name servers world-wide to be updated and able to access the information. This 72-hour period is referred to as DNS propagation.
