The NS (Name Server) records of a domain name reveal which DNS servers are authoritative for its zone. In simple terms, the zone is the collection of all records for the domain name, so when you open a URL within a browser, your laptop or computer asks the DNS servers worldwide where the domain address is hosted and from which servers the DNS records for the domain must be retrieved. In this way a browser finds out what the A or AAAA record of the domain is so that the latter is mapped to an IP address and the website content is required from the right location, a mail relay server finds out which server deals with the e-mails for the domain name (MX record) so that a message can be sent to the needed mailbox, and so forth. Any change of these sub-records is done using the company whose name servers are used, enabling you to keep the website hosting and switch only your email provider for example. Every single domain name has a minimum of 2 NS records - primary and secondary, which start with a prefix like NS or DNS.
NS Records in Website Hosting
If you use a website hosting plan from our company and you include a new domain name in the account or transfer an existing one from a different company, you are going to be able to manage its NS records easily through the Hepsia hosting CP, provided 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 several domain addresses at a time with several clicks. This is done using the feature-rich Domain Manager tool that is a part of Hepsia and the user-friendly interface is going to make it easy to handle your domain address even if it is the first one you've ever registered. It requires just a click to see what name servers a domain name uses at the moment or if they are the correct ones to direct a domain name to the hosting space on our end and with a few clicks more you are going to even be able to register private name servers for each of the domains that you own. For the latter option you can use the IP addresses of any provider that you'd like the new NS records to forward to.
