The NS (Name Server) records of a domain reveal which DNS servers are authoritative for its zone. Essentially, the zone is the range of all records for the domain, so when you open a URL inside a web browser, your personal computer asks the DNS servers globally where the domain is hosted and from which servers the DNS records for the domain name must be retrieved. This 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 address and the website content is requested from the proper location, a mail relay server finds out which server deals with the emails for the domain address (MX record) to ensure that a message can be sent to the needed mailbox, and so forth. Any change of these sub-records is performed using the company whose name servers are employed, allowing you to keep the web hosting and change only your email provider for example. Every single Internet domain has at least two NS records - primary and secondary, which start with a prefix such as NS or DNS.
NS Records in Cloud Web Hosting
If you use a cloud web hosting from our company and you add a new domain name within the account or transfer an existing one from a different provider, you'll be able to control its NS records effortlessly using the Hepsia hosting CP, which comes with all shared accounts. You'll be able to change the current name servers or enter additional ones for a single domain address or even for many domain names simultaneously with several mouse 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 control your domain address even if it is the first one you have ever registered. It requires only a mouse click to see what name servers a domain uses at the moment or if they're the correct ones to point a domain address to the hosting space on our end and with only a couple of mouse clicks more you will 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 IP addresses of any company that you would like the new NS records to point to.
