Unbound
Use the default unbound.conf or one specifically for OpenNIC and have setting similar to the following:
server: verbosity: 1 statistics-interval: 3600 interface: <your IP address> access-control: 0.0.0.0/0 allow # this path is for OpenBSD root-hints: "/var/unbound/etc/opennic.cache" hide-version: yes log-queries: no
There are various other settings to tune your threads etc.
You will then need to get a copy of the root cache file and update it as per the instructions on this page.
