When registering a domain name, if your site will be hosted on RealHOST hosting, you should specify the following domain NS servers:
- - ns1.realhost.pro
- - ns2.realhost.pro
- - ns3.realhost.pro
If you need to point the registered domain name to a third party host, check the NS with the third party host and set them for your domain.
In the future, the domain extension will be carried out through RealHOST, and all settings of the domain zone should be carried out on a third-party hosting.
