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

localhost A 127.0.0.1
; @ MX 10 mail
@ MX 10 mailin.easynet.de.
@ MX 20 relay.mail.de.easynet.net.
@ NS ns.easynet.de.
@ NS ns.easybone.net.
; delegate subdomains
; drake-network.de, 212.224.47.64/27
64-27 NS ns.drake-network.de.
;
65 CNAME 65.64-27
66 CNAME 66.64-27
67 CNAME 67.64-27
...
94 CNAME 94.64-27
-----------------------------------

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)

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.
