in thread net::dns::update and in-addr.arpa ??

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?

    HTH, --traveler

      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);
        Resolved. Do a 'dig -x' on a valid IP address on the network. The "AUTHORITY SECTION" shows the in-addr.arpa zone to use for the 'new Net::DNS::Update' parameter.
