Quick query about running BIND in the chroot (jailed) environment.

In earlier versions, we used to have forwarders i.e. Pulic DNS Servers configured in named.conf

Now I have successfully set up the same in RHEL 7. Lookup works okay yet I cannot figure out how the setup is forwarding some requests.

I have no Public DNS entries in neither the ethernet conf file nor resolv.conf

Where is the forwarding happening ?
