bind-users Digest, Vol 3907, Issue 3

[muhanad at plciq.com]

Ok , this is one issue solved ; I have another issue.

The main domain from previous ( example.com ) needs to be forwarded to the
internet and resolved normally, and with current configuration when I 
do nslookup from inside the NDS server it resolves normally , the problem is
with client machines when they use my DNS the main domain ( example .com,
aa.example.com) don't reply back and the nslookup shows no results. Below
are the zone config.

$TTL    604800
@       IN      SOA     ns1.plciq.com. root.plciq.com. (
                        602172022       ; Serial
                         604800         ; Refresh
                          86400         ; Retry
                        2419200         ; Expire
                         604800 )       ; Negative Cache TTL
;

@       IN      NS     ns1.plciq.com
ns1     IN      A      192.168.1.1
*       IN      A      192.168.1.5
*       IN      A      192.168.1.6

These are subdomains too.
And this is how wildcards work, you can't change it.

If you don't like it, you'll have to list all records.
if there are the same records with multiple addresses, you can define

wildcard.example.com.	A	192.0.2.1
			A	192.0.2.2
			A	192.0.2.3
bb.aa.example.com.	CNAME	wildcard.example.com.
cc.aa.example.com.	CNAME	wildcard.example.com.

etc.

Ah, good point Grant.

The reverse zones are delegated to us but they aren't signed.
