in reply to net::dns::update and in-addr.arpa ??

Some things to check:
  1. Do you have permission to update that zone (the w.z.y.z.in-addr.arpa zone)
  2. What are $host, $ip and $type? I guess the important one here is $type. Is it "PTR"?
  3. What is the value of $DnsDomain? Is it something like ".foo.com." (with the ".")
  4. Finally, should the Update->new() call refer to $DnsDomain or $revZone? I am not sure as I have not used Net::DNS::Update.

    Hi, thanks so far - but i think I have to explain my problem in more detail:
    I use the examples from net::dns::update. Adding or deleting A records works great!
    But there are no examples how to write PTR records to in-addr.arpa zones.
    i have tried syntax like those from "nsupdate" :
    update: {add} 13.13.168.192.in-addr.arpa. 86400 IN PTR testhost.foo.com.
    but with no success ! (NOTZONE RETURN CODE from DNS-Server)

    here is my example without variables:
    .
my $update = Net::DNS::Update->new(foo.com);
$update->push("pre", nxrrset("3.13.168.192.in-addr.arpa. PTR testhost.
+foo.com."));
$update->push("update", rr_add("$3.13.168.192.in-addr.arpa. 86400 IN P
+TR testhost.foo.com."));

my $res = Net::DNS::Resolver->new;
$res->nameservers(nameserver.foo.com);
my $reply = $res->send($update);
.

    answers to the questions:
    as far as i know there shold be a "dot" after the domain name (testhost.foo.com.)
    Net::DNS::Update->new should refer to den DNS domain
    there are no right problems...

      I now believe that the issue is what I mentioned, you are not updating foo.com; you are updating in-addr.arpa. Try making that the arg to new. Also I presume the $ before the IP is a typo?

        10 years later and I have this exact same problem. Can't figure out how to add a PTR record using Net::DNS. I wonder if OP ever figured this out...

        The syntax of my rr_add is: rr_add(X.XXX.XXX.XX.in-addr.arpa 3600 PTR hostname.mydomain.com.)

        Is this correct? Thanks in advance... 
           # Create the update packet:
   my $update = Net::DNS::Update->new($OURDOMAIN);

   #  Add the PTR record:
   $update->push(update => rr_add("$rev 3600 PTR $hst"));

   # Send the update to the zone's primary master.
   my $res = Net::DNS::Resolver->new;
   $res->nameservers("$OURNMSERV");

   my $reply = $res->send($update);
