Disconnected the domain from "Yandex.Mail", and he was stuck somewhere in weightlessness ..?

Question

Domain Name System

Hello, such a situation, I will try to be brief, so that someone who decides to tell me does not have to read a lot ...

- registered a domain;
- parked on "Yandex.Mail";
- bought a hosting;
— Decided to repark the domain.

From the hosters I chose "fornex.com" - I almost did not find bad reviews. Yes, and Russian technical support attracted.

In the help, fornex writes (like everyone else) what needs to be changed at the registrar (in this case, Yandex) NS-server:

IP
hostname ns1.fornex.com
37.59.133.13 ns2.fornex.com 212.224.124.82
ns3.fornex.com 50.19.122.134
ns4.fornex.com 176.34.232.101

My actions in the yandex account:
- delete all NS records;
- I insert here such records;

@ NS ns1.fornex.com
@ NS ns2.fornex.com
@ NS ns3.fornex.com
@ NS ns4.fornex.com

— disable domain parking;

Days pass after these steps.
— the domain is not available;

- Yandex support replied:

Good afternoon!

You have disabled the jdev.name domain from the Yandex.Mail service.

Is it ok right? I'm just doing this for the first time and I don't understand why. It says it can take up to 72 hours. But for example, I parked to Yandex, waited less than a day ...

Thanks for the answers, and please - if everything is obvious to someone, then it’s not very good for me.

Answer 1

You need to change ns-records at the domain registrar. Yandex in this case is just a parking attendant.
If you want to continue with Yandex mail on your domain, then at the same registrar you need to change mx-records to Yandex ones.

Answer 2

And how did Yandex become a registrar? at the registrar you delegated the domain to Yandex, respectively, the named server at the registrar had to be changed. or on Yandex to make a different type of record

Answer 3

Go to the registrar and indicate his NS records. The button should be called something like "Delegate domain".
Changing NS to I will do nothing.
