Hello Sir,
Good day to you.

Why I can not find the NS record when registering a new domain ?

I can find all of other records but NS is not among them

Regards,

You have to register the domain name first before you can specify the name servers for the domain name. After registration, you can manage the NS records in the 'Name Servers' area. You can use name servers other than Dynu name servers if you register a domain name at Dynu.

If you transfer a domain name, the existing name servers will be transferred as well.

You cannot change the name servers for the free third domain names offered by Dynu. For example, if you obtain a free third level domain name such as yamazaki.kozow.com, you cannot change its name servers.
