Hi there..
I'm trying to create a delegation to a sub-domain ; for some reasons
I'm getting no-where
I have a domain.com zone ; I'd like to delegate mel.domain.com to
another dns server (windows server DNS fwiw)
Here is my zone file:
$ORIGIN .
$TTL 7200 ; 2 hours
domain.com. IN SOA m.domain.com. domainmaster.domain.com. (
2011020405 ; serial
7200 ; refresh (2 hours)
1800 ; retry (30 minutes)
1209600 ; expire (2 weeks)
86400 ; minimum (1 day)
)
NS m.domain.com.
MX 0 mail.domain.com.
$ORIGIN domain.com.
A 192.168.0.2
; glue record
m A 192.168.0.2
mel A 192.168.0.3
; NS ad.domain.com
ad A 192.168.0.3
---
when NS ad.domain.com line is commented out ; querying for
mel.domain.com is properly resolved:
bash-3.2# dig @192.168.0.2 mel.domain.com
; <<>> DiG 9.6.0-APPLE-P2 <<>> @192.168.0.2 mel.domain.com
; (1 server found)
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 2718
;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 1

mel.domain.com. 7200 IN A 192.168.0.3

Now if I uncomment the NS ad.domain.com. mel.domain.com will not
resolve anymore:
bash-3.2# dig @192.168.0.2 mel.domain.com
; <<>> DiG 9.6.0-APPLE-P2 <<>> @192.168.0.2 mel.domain.com
; (1 server found)
;; global options: +cmd

;; MSG SIZE rcvd: 32
For what it's worth; ad.domain.com (the other dns server) properly
answer the query:
bash-3.2# dig @192.168.0.3 mel.domain.com
; <<>> DiG 9.6.0-APPLE-P2 <<>> @192.168.0.3 mel.domain.com

Could someone explained to me what I'm doing wrong ?
I've read every documents I could find on this topic ; and they are
all doing a similar thing ...
Why can't I define NS for my mel.domain.com ?
Thank you
