The NS (Name Server) records of a domain reveal which DNS servers are authoritative for its zone. Basically, the zone is the group of all records for the domain address, so when you open a URL in a web browser, your computer asks the DNS servers worldwide where the domain name is hosted and from which servers the DNS records for the domain must be retrieved. That way a browser finds out what the A or AAAA record of the domain address is so that the latter is mapped to an IP and the site content is requested from the proper location, a mail relay server discovers which server takes care of the emails for the domain name (MX record) so a message can be forwarded to the needed mailbox, and so on. Any modification of these sub-records is conducted with the help of the company whose name servers are employed, so you're able to keep the web hosting and switch only your email provider for instance. Every domain address has a minimum of 2 NS records - primary and secondary, that start with a prefix such as NS or DNS.
NS Records in Hosting
When you use a hosting from our company and you register a new domain inside the account or transfer an existing one from another company, you'll be able to handle its NS records easily through the Hepsia web hosting Control Panel, provided with all shared accounts. You'll be able to change the current name servers or enter additional ones for a single domain or even for many domain names simultaneously with several clicks. This is done using the feature-rich Domain Manager tool that is a part of Hepsia and the user-friendly interface will make it simple to handle your domain name even if it's the first one you have ever registered. It requires only a click to see what name servers a domain name uses at the moment or if they are the correct ones to point a domain to the hosting space on our end and with a few mouse clicks more you are going to even be able to register private name servers for any one of the domain names that you own. For the latter option you can use the IPs of each provider that you want the new NS records to forward to.
