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 range of all records for the domain address, so when you open a URL in a browser, your personal computer asks the DNS servers around the globe where the domain address is hosted and from which servers the DNS records for the domain ought to be retrieved. In 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 site content is requested from the correct location, a mail relay server discovers which server deals with the e-mails for the domain name (MX record) to ensure a message can be sent to the needed mailbox, etc. Any change of these sub-records is done with the help of the company whose name servers are employed, so you're able to keep the website hosting and change only your email provider for instance. Each and every domain has at least two NS records - primary and secondary, that start with a prefix such as NS or DNS.
NS Records in Semi-dedicated Servers
When you register a new domain name within a semi-dedicated server account or transfer an existing one from another registrar provider, you will be able to update its NS records as needed without any problems even if you have not had a domain name of your own before. The process takes a few mouse clicks in Hepsia - the user-friendly control tool, which comes with our semi-dedicated solutions. If you have many domains inside the account, you're going to be able to update all of them at once, which can save you lots of time and clicks. Additionally you can see with ease the name servers which a domain name uses and if they are the proper ones or not as a way for the domain address to be pointed to the account that you have got on our advanced cloud hosting platform. Hepsia will also allow you to set up private name servers under any domain registered within the account and use them not only for that domain name, but also for any other one that you want to point to our cloud platform.
