Delegation of reverse lookup /27

[Jan Beers]

Hello all,

I am trying to delegate the 212.224.47.64/27 ip-range reverse lookup to
that owner's nameserver (ns.drake-network.de), according to bind faq and
rfc2317

I have the feeling that I am forgetting/missing something.

server setup (ns.easynet.de) (bind 8.2.3)

$ORIGIN 47.224.212.in-addr.arpa.
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; 47.224.212.in-addr.arpa
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

@       NS      ns.easynet.de.

66      CNAME   66.64-27
67      CNAME   67.64-27
...
94      CNAME   94.64-27

-----------------------------------

setup ns.drake-network.de: (bind 8.2.3)

                IN      NS      ns.easynet.net.

67              IN      PTR     67.isdngw.drake-network.de.
...
94              IN      PTR     ns.drake-network.de.

---------------------------------------------

In the moment, all I get is this:

sh-2.02$ dig -x 212.224.47.66 @ns.easynet.de

; <<>> DiG 8.1 <<>> -x @ns.easynet.de
; (1 server found)
;; res options: init recurs defnam dnsrch

66.64-27.47.224.212.in-addr.arpa.
.....
------------------------------

if I use nslookup, I get this.

sh-2.02$ nslookup 212.224.47.66 ns.easynet.de
Server:  ns.easynet.de
Address:  194.24.209.90

Authoritative answers can be found from:
64-27.47.224.212.in-addr.arpa   nameserver = ns.drake-network.de
ns.drake-network.de     internet address = 212.224.47.94
*** No address (A) records available for 212.224.47.66

strange enough, if I use nslookup on my local dns server, it *does*
resolve

sh-2.02$ nslookup 212.224.47.66
Server:  peppone
Address:  xx.x.xx.x

Name:    isdngw.drake-network.de
Address:  212.224.47.66
Aliases:  66.47.224.212.in-addr.arpa



What else do I need on eighter side of this setup? setup slave-zones
somewhere?
Delegate something else? Any hints appreciated.
