To find information about the domain we can use the whois command. Since we are finding the IANA ID, we can grep for that. Below is the offical solve method.

❯ whois vipinb.xyz | grep "IANA ID"
Registrar IANA ID: 1636
Registrar IANA ID: H2712453
❯ echo -n 'H2712453' | shasum -a 256 | awk '{print "csd{"$1"}"}'
csd{39d569bc0fc532d2993920f1f1bf0fabf82b510d44471374045672d7a15f33b0}
