==== 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 **[[Tier2ConfigBindHint|on this page]]**.
