Disable DNS forwarding

cormanstnl · 10-08-2008, 06:23 AM

Hi all,

I have a bind9 server. I want to configure my server for only resolve zone available by the config. If a address like an internet URL is asked to the server, bind must not try to forward the request to other an server. it must directly says : unknow.

config like

forwarders: {};
forward-only;

I'm not sure that I can put no forwarders IP.

comment out the forwarders parameter.

your server will only look at zone that you had configured.

OK...

I have an other question :

In bind log categroy query, we have two type of answer :

08-Oct-2008 13:25:15.587 client ii.iii.i.ii#41165: query: uuuuuu.uuu.uuuuuuuu.uuuuuuuu IN A +
08-Oct-2008 13:31:28.890 client xx.x.x.xx#1061: query: uuuuuu.uuu.uuuuuuuu.uuuuuuuu IN A -

What is the difference between A + et A - ?
