    I'm a little bit in the mix and I need some help.
    Recently I've requested to my ISP to delegate the reverse lookup to all my IP's. So acording to manual I've created a DNS Zone "" and in it a PTR Record with 147 at Name and "mail.mydomain.tld." at data. I've wait at least 24 hours to propagate and made a check at and there the result is


    CNAME 24 hrs

    If someone cand point me in the right direction...

    create a dns-zone with a ptr-record with the canonical hostname mail.mydomain.tld.

    I've made the modification as you said and now in my syslog I've see this

    Dec 20 10:37:48 isp named[23826]: client query (cache) '' denied

    It's something wrong (bind service is restarted)

    Please check that you allow queries in your bind-setup.

    allow-query { any; }; in /etc/bind/named.conf

    In my named.conf (Ubuntu) have only
    include "/etc/bind/named.conf.options";
    include "/etc/bind/named.conf.local";
    include "/etc/bind/named.conf.default-zones";
    Maybe in include "/etc/bind/named.conf.options"?
