I understand that this is the way a PTR record would be made on a Class A subnet (10.100.250.100 255.0.0.0)
dnscmd /RecordAdd 10.in-addr.arpa. 100.250.100 PTR host.domain.tld
To clarify the syntax, this is what it should be for a Class C subnet (192.168.1.100 255.255.255.0)
dnscmd /RecordAdd 1.168.192.in-addr.arpa. 100 PTR host.domain.tld
Is that right?
Now how do I do this for a host with the IP address 172.31.111.210 on a 172.31.111.192/26 network? I'm not sure how to do this with a classless subnet mask.
