A DNS server is an application that responds to DNS queries using the appropriate protocol. It can also be the host running the requested application. Any internet hosting has its own DNS server, and for the site to work, you need to register the hosting address in the DNS settings.
Instructions
Step 1
Any paid hosting provides its client with its own DNS zones, if the hosting is not a domain registrar, or you transferred the domain to hosting, registering it earlier in another place. To make the sites work on third-party hosting (not hosting the registrar), you need to change the NS zones: NS1 and NS2. This is done in the domain registrar account.
Step 2
Go to the site where you registered the domain whose DNS you want to change. Find the required URL in the list of paid domains and select "Delegation" or "Manage DNS servers" in the settings or parameters of the domain. Different registrars call this item differently.
Step 3
After you follow the link, the screen will display empty fields DNS 1, DNS 2, DNS 3 and DNS 4, as well as symmetric fields for entering IP. Fill in the DNS 1 and DNS 2 fields, indicating the ns addresses provided by the hosting (such as ns1.hosting.ru and ns2.hosting.ru).
Step 4
The rest of the fields are usually left blank. After the performed operation, save the changes - usually there is a button "Save" or "Change" for this. If in the same window you are offered to use the registrar's addresses, but hosting is not, uncheck this box. Also uncheck the "Remove domain from delegation" option, if there is one.
Step 5
A complete update of DNS zones takes place within 6-12 hours. Your site will be available on new servers after this time. Providers' DNS update takes up to 48 hours, therefore, after changing the DNS server, from some computers the site may be unavailable for a day or two.
