The NS (Name Server) records of a domain show which DNS servers are authoritative for its zone. In simple terms, the zone is the range of all records for the domain address, so when you open a URL in an Internet browser, your personal computer asks the DNS servers worldwide where the domain name is hosted and from which servers the DNS records for the domain should be retrieved. With this a browser finds out what the A or AAAA record of the domain is so that the latter is mapped to an Internet protocol address and the web site content is required from the correct location, a mail relay server detects which server manages the e-mails for the domain (MX record) so that a message can be forwarded to the needed mailbox, and so forth. Any modification of these sub-records is performed using the company whose name servers are used, so you're able to keep the web hosting and switch only your email provider for instance. Every domain name has a minimum of 2 NS records - primary and secondary, that start with a prefix like NS or DNS.
NS Records in Shared Web Hosting
If you use a Linux shared web hosting from our company and you register a new domain name within the account or transfer an existing one from a different provider, you're going to be able to handle its NS records effortlessly through the Hepsia web hosting Control Panel, which comes 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 a number of domains at once with several clicks. This is done using the feature-rich Domain Manager tool which is a part of Hepsia and the user-friendly interface is going to make it simple to manage your domain even if it is the first one you've ever registered. It takes simply a mouse 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 only a few mouse clicks more you will even be able to register private name servers for any one of the domains that you own. For the latter option you can use the IPs of every provider that you would like the new NS records to point to.
