The NS, or Name Server records of a domain name, point out which servers deal with the Domain Name System (DNS) records for it. Setting the name servers of a specific host company for your domain address is the most effective way to forward it to their system and all its sub-records will be handled on their end. This includes A (the IP address of the server/website), MX (mail server), TXT (free text), SRV (services), CNAME (forwarding), and so on, if you need to edit any of these records, you are going to be able to do it via their system. Put simply, the NS records of a domain name reveal the DNS servers that are authoritative for it, so when you attempt to open a web address, the DNS servers are contacted to get the DNS records of the Internet domain you are attempting to reach. In this way the site that you will see is going to be retrieved from the correct location. The name servers usually have a prefix “ns” or “dns” and every single domain address has at least two NS records. There is no practical difference between the two prefixes, so what type a hosting provider is going to use depends completely on their preference.
