Jun 24 11:49:40 server named[4245]: running


My named.conf os as follows,

options
{
query-source port 53;

directory "/var/named"; // the default
dump-file "data/cache_dump.db";
statistics-file "data/named_stats.txt";
memstatistics-file "data/named_mem_stats.txt";

};

controls
{
inet 127.0.0.1 port 953 allow { 127.0.0.1; } keys { "rndckey"; };
};

logging
{
channel default_debug
{
file "data/named.run";
};
channel update_debug
{
file "data/update-debug.log";
severity debug 3;
print-category yes;
print-severity yes;
print-time yes;
};
channel security_info
{
file "data/named-auth.info";
severity info;
print-category yes;
print-severity yes;
print-time yes;
};

category update { update_debug; };
category security { security_info; };

};
// view "internal"
//{
// match-clients { localhost; 10.0.0.0/8; };
/// match-destinations { localhost; 10.0.0.0/8; };
// recursion yes;
// notify yes;
// include "/etc/named.bionline.zones";
//};

include "/etc/rndc.key";

key biwebmail
{
algorithm hmac-md5;
secret "my --key--";
};


Can anyone please tell me why the log shows empty zones related to IPv6 and all when no zones are defined in named.conf.From where all these information comes ?

Note : View section is commented just for testing purpose.

well it says in the log that it's an automatic default... is something actually wrong?

Thanks Chris!

Though nothing is wrong i want to remove configuration related to IPv6 from my DNS server since i am not using any v6 IP numbers.

i assume that RFC's and other standard dictate that they must be there for a tefchnically correctly dns server. you have no obligation to utilize them at all.

Ok Thanks Chris.
