Hi, I have a domain name of ISNIC.

you may already know, digitalocean’s nameserver 1 and 2 are same ip address.

ns1.digitalocean.com 139.59.142.21 ns2.digitalocean.com 139.59.142.21 ns3.digitalocean.com 128.199.231.60

Because of this, ISNIC domain doesn’t delegate to digitalocean server.

In ISNIC domain restriction,

At least two different nameservers must be specified (and the hosts must not resolve to the same IP address).

Why ns1 and ns2 are same ip address?

Where did you get those IP addresses? They’re incorrect.

Hello, how are you? The nameservers are always going to be “ns1.digitalocean.com”, “ns2.digitalocean.com”, etc. right? And where are the different ip of my server?. Since I have only one ipv4 and one ipv6.

Thank you!
