Nameserver can be defined as the computers accessible on the Internet which explains the location of the website. Resolving is the process which is done by Nameservers. During this process, the domain name of the website is taken and with the help of the Domain Name System (DNS) which keeps the data of the domain names and the corresponding IP addresses, the IP (Internet Protocol) address corresponding to the domain name is given. The location of the website on the internet is determined by the IP address and this is also called as Nameservers. It is also known as DNS servers as they perform the same function (Return the IP address for the domain when a domain name is given). When you buy or configure a Domain name for your website you will have to provide the names of the namesservers as this is very important. When you go for a web hosting package for your website your web hosting provider will ask you for the names of these nameservers. Also, these nameservers are of two types, one is the Primary Nameservers and the other is the Secondary Nameservers.

Primary server:-

You will have to enter the host name and the IP number of the name server in the column given registrant of your domain and this will contain the authoritative information of the domain name and this will be used to resolve that domain name to the corresponding IP address of the domain name. This is know as primary name server as this will be used first to resolve the domain name and the name server which will be entered after this will be considered after this name server. If this column is not filled, the domain name registrar will not proceed further with the process of registering the domain name as this is one of the most important section of the agreement.

Second level domain:-

These domains are considered to be the most important after the top level domains. For example, 1stDomain.com – the “1stDomain.com” part is the second level domain. These domains are registered under the top level domain registry.
