why my DNS server needs listen-on-v6 { any; };?

[cccc]

hi

I have an internal DNS server BIND 9.2.2 running on linux SUSE 8.2

If I disable (#)
# listen-on-v6 { any; };
then DNS after restart doesn't work.

I don't need ipv6

know someone what's wrong?

my config file:

options {

directory "/var/lib/named";

auth-nxdomain yes;
multiple-cnames no;
cleaning-interval 60;
datasize default;
stacksize default;
coresize default;
files unlimited;
# recursion yes;

forwarders { X.X.X.X; X.X.X.X; X.X.X.X; };

forward first;

# listen-on port 53 { 127.0.0.1; };
listen-on port 53 { 192.168.1.1; };

listen-on-v6 { any; };

#query-source address * port 53;
#transfer-source * port 53;
#notify-source * port 53;

#allow-query { 127.0.0.1; };

notify no;
};

This is one of these cases where "doesn't work" will need clarification. Probably even a snap of a logfile.
