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 188.8.131.52 ns1.itgreen.info
184.108.40.206.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 220.127.116.11
** server can't find 18.104.22.168.in-addr.arpa.: NXDOMAIN
I dont' know why the zone not yet been propagated correctly..
Since the change was made three days have passed..
