BIND 9 and in-addr.arpa subdomains

carsten.engel · 07-15-2005, 05:14 AM

I try to do subdomains for my 17.172.in-addr.arpa zone.

I tried to put in my config file the following lines:

Code:

$ORIGIN .
$TTL 172800     ; 2 days
17.172.in-addr.arpa     IN SOA  lnx2.bar.foo.intern. emil.lnx2.bar.foo.intern. (
                                2005071502 ; serial
                                10800      ; refresh (3 hours)
                                3600       ; retry (1 hour)
                                604800     ; expire (1 week)
                                86400      ; minimum (1 day)
                                )
                        NS      lnx1.bar.foo.intern.
                        NS      lnx2.bar.foo.intern.

$GENERATE 024-027 $17.172.in-addr.arpa. 86400 IN NS lnx3.goog.bar.foo.intern.

I received the following error in the syslog...

Code:

Jul 15 11:58:30 lnx2 named[4802]: $GENERATE: master/17.172:12: unknown RR type '86400'
Jul 15 11:58:30 lnx2 named[4802]: zone 17.172.in-addr.arpa/IN: loading master file master/17.172: unknown class/type

I'm not 100% up on what all of the variables do in bind zone files, but for a PTR record in the reverse zone all you should need is:

1 PTR full.hostname.tld.

And for the NS record:

NS full.hostname.tld.

Thanks Noth,
If I have to delegate a whole subdomain to another Nameserver. Forward and Reverse, whats the best way to do that?

If I do like you said, I would only hint the forward zone to another nameserver. Am I wrong with these Idea?

I believe you just need to setup the delegated zone as a stub zone in named.conf

Is there not a big difference between a stub zone and a delegation.

Stubzones only hint to other nameservers, delegation is a complete subdelegation of a subdomain.

I`m not sure, that a stub zone will help me in this case.

Honestly, I'm not sure since I've never had to deal with delegation. Check out the following URL and see if it helps at all.

Thanks for the link. But this doesn´t help either. I have to delegate a in-addr.arpa zone of a B-Class Network.

So far, I have the impression, that there´s nobody who deals with delegated Zones with Bind.

But again thanks for your help.

Until I have another solution, I try your hint with the stub zones.

Probably anyone else has an idea, why my delegation wouldn´t work.
