The Name Servers of a domain name show the DNS servers that are responsible for its DNS records. The Internet protocol address of the website (A record), the mail server that handles the emails for a domain address (MX records), any text record in free form (TXT record), forwarding (CNAME record) and so forth are extracted from the DNS servers of the hosting company and for any domain name to be using them and to be directed to their hosting platform, it has to have their name servers, or NS records. If you would like to open an Internet site, for instance, and you insert the URL, the Internet browser connects to a DNS server, which keeps the NS records for the domain address and the request is then sent to the DNS servers of the hosting provider where the A record of the web site is retrieved, so that you can view the content from the proper location. Normally a domain has a couple of name servers that start with NS or DNS as a prefix and the distinction between the two is only visual.
