It uses them to determine the NS for the domain name you want. to run
bind at its quickest, using your own root zone can help.

I aggregate a root zone to run on my name servers. You may grab the
zone if you would like to give it a try. slave '. zone from

zone "." IN{
        type slave;
        file "/etc/bind/db.root";
        masters {; };
        allow-transfer { any; };
        notify no;

Once this done, you will have no need to forward to your ISP.
Hope that helps!
