Is it possible to attach a domain to my hosting without the participation of a domain registrar?

Question

Domain name market

How do website builders implement the attachment of a purchased domain to generated pages? After all, for this I do not need to go to change the DNS-ki at the registrar. Is there any other way to do this?

Answer 1

Why is it not necessary for the designers, you just need to set their DNS and then everything starts working. Or perhaps you mean the option when they register a domain for you, then yes they immediately set it up and it seems to you that you do not change them.
For a domain on a nethouse, for example, to work there must be ns1.nethouse.ru ns2.nethouse.ru or something like that
