I keep seeing the following error messages coming up on my DNS screen
since enabling dynamic DNS.

client xx.xx.xx.xx update xx.xx.IN-ADDR.ARPA/IN denied

Some of the addresses that give the above do still register though?
One thing it says when creating the in addr arpa is that you should
create a ptr record for the dns server but the dns I dont currently
have any dns servers that are in the range.

ive created a 175.10 in .........
But the authoritive server doesnt have an ip address that starts with

Any ideas how to stop these errors appearing??
