The NS (Name Server) records of a domain reveal which DNS servers are authoritative for its zone. Essentially, the zone is the collection of all records for the domain name, so when you open a URL in a browser, your computer asks the DNS servers around the globe where the domain address is hosted and from which servers the DNS records for the domain address should be retrieved. With this a web browser finds out what the A or AAAA record of the domain address is so that the latter is mapped to an Internet protocol address and the site content is required from the proper location, a mail relay server detects which server deals with the emails for the domain (MX record) to ensure a message can be sent to the right mailbox, and so forth. Any change of these sub-records is done through the company whose name servers are employed, allowing you to keep the web hosting and change only your email provider for instance. Each and every domain address has at least 2 NS records - primary and secondary, which start with a prefix such as NS or DNS.
NS Records in Shared Website Hosting
When you use a shared website hosting from our us and you register a new domain inside the account or transfer an existing one from another provider, you are going to be able to manage its NS records with ease through the Hepsia hosting CP, offered with all shared accounts. You are able to change the current name servers or enter additional ones for a single domain or even for several domain addresses at the same time with several clicks. This is done via the feature-rich Domain Manager tool that's a part of Hepsia and the user-friendly interface will make it easy to control your domain even if it is the first you have ever registered. It requires simply a mouse click to see what name servers a domain address uses at the moment or if they are the correct ones to point a domain name to the hosting space on our end and with only a couple of clicks more you will even be able to register private name servers for each of the domain names that you own. For the latter option you can use the IP addresses of each provider that you would like the new NS records to forward to.
