EdgeDNS is a DNS reverse proxy written in Erlang that mitigates DNS Amplification attacks using a dampening technique inspired by Lutz Donnerhacke.

Erlangs native configuration format can be quite a drag, especially for non-erlangers. Therefore a YAML formatted configuration file can used with EdgeDNS instead. It is possible to omit the YAML config and configure EdgeDNS using the classical way with rebar3 and semi-readable erlang-terms. See the section below for details.
An example configuration file is supplied here
which includes descriptions of each option. When EdgeDNS i started it searches for a
configuration file named edgedns_config.yml in the following places (and order):
./~/.edgedns/usr/local/etc/etc
When a file is found it stops searching. Both filename and the list of places to search can be configured as well, as explained in the section below.
