# Set up a basic named.conf file.
# Brew directory could be slightly different mine is this /usr/local/Cellar/bind/9.10.1-P1/

# If you are using some third party DNS you should add: nameserver 127.0.0.1 in /etc/resolv.conf
# If your resolv.conf file is automaticaly generated you should change it on startup in order to work properly
