reverse ok... but propagate zone..
thanks a lot for your support...i have configurated zone on your instructions and now the reverse ip work correctly..
If I try to do nslookup by dns server I receive the correct response:
andrea@ubuntu-malago:~$ nslookup 18.104.22.168 ns1.itgreen.info
22.214.171.124.in-addr.arpa canonical name = 34.0-24.
But if I try to resolv ptr zone by another dns i receive error message
catterin@jest-pub:~$ nslookup 126.96.36.199
** server can't find 188.8.131.52.in-addr.arpa.: NXDOMAIN
I dont' know why the zone not yet been propagated correctly..
Since the change was made three days have passed..
