ns1.digitalocean.com & ns2.digitalocean.com are same ip address!

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 ns1.digitalocean.com
ns1.digitalocean.com.  (unsigned)  1800  A     173.245.58.51
ns1.digitalocean.com.  (unsigned)  1800  AAAA  2400:cb00:2049:1::adf5:3a33
$ 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
ns3.digitalocean.com.  (unsigned)  300  A     198.41.222.173
ns3.digitalocean.com.  (unsigned)  300  AAAA  2400:cb00:2049:1::c629:dead
  • Ooooops..
    When I put nameserver to onlydomains management page,
    they show me same address.
    but they're incorrect..

    Thanks! I'm gonna change wrong address to correct ip4 address
