The "." zone below tells named to check this file for a list of the root name servers, so it knows where to send external queries.
If you don’t have that I suggest that you first read my two other posts on how to install them: Setting up a DNS for the local network on the Ubuntu 12.04 (Precise Pangolin) server Setting up a DHCP server on Ubuntu 12.04 (Precise Pangolin) server Step by step instructions Apparently the Ubuntu server is installed with an App Armor profile that prevents bind to write to the /etc/bind directory.
It also stores other types of records that helps in delivery of different types of information from one end of the Internet to the other.
This is especially useful if you are running IIS and have a lot of sites and don't want to use a 3rd party option for DNS.
If you connect the Internet facing server to the rest of your DNS servers you will have your internal network AD information stored on there.
Should this external facing server get hacked or compromised they would find quite a bit more information than just some publicly available resource records.
