The NS (Name Server) records of a domain show which DNS servers are authoritative for its zone. Simply, the zone is the range of all records for the domain address, so when you open a URL inside a browser, your laptop or computer asks the DNS servers worldwide where the domain name is hosted and from which servers the DNS records for the domain must 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 website content is requested from the correct location, a mail relay server finds out which server handles the emails for the domain name (MX record) so that a message can be forwarded to the appropriate mailbox, and so on. Any modification of these sub-records is done using the company whose name servers are employed, so that you can keep the web hosting and switch only your email provider for instance. Every single domain has a minimum of two NS records - primary and secondary, that start with a prefix such as NS or DNS.
NS Records in Semi-dedicated Servers
If you go for a semi-dedicated server account from our company, you'll be able to manage the NS records of every domain address registered inside it with ease. The Hepsia Control Panel, which is basically an all-in-one tool for you to handle everything associated with your web presence, comes with a very simple and easy-to-use interface. The section in which you will find all your domains isn't an exception, so even if you haven't had a domain name and a hosting account before, updating the name servers or entering additional ones is not going to take you more than a few mouse clicks. You will also have the ability to see with a glance what name servers every one of your domain addresses uses right now and if they are the ones required to point that domain name to the semi-dedicated account. As an extra feature, we give you the opportunity to create child name servers dns1/2.your-domain.com at no extra cost. This will give more credibility to your site, especially if it's a business one, and you may use these name servers for any other domain address that you'd like to host in the semi-dedicated account as well.
