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,
1) 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.

$ mhost ns2.digitalocean.com
ns2.digitalocean.com.  (unsigned)  1800  A     173.245.59.41
ns2.digitalocean.com.  (unsigned)  1800  AAAA  2400:cb00:2049:1::adf5:3b29
$ mhost ns3.digitalocean.com
