Configuring GeoDNS

Once you have the GeoDNS package running, make a configuraton for it.

From above, if we are running the geodns in the same directory, our configuration.

mkdir dns
./src/github.com/abh/geodns/geodns \
	-http="0.0.0.0:8053" \
	-identifier="$(hostname -f)" \

Example Configs
The geodns.conf is a simple INI file.



Each domain is a JSON file, named after the domain, like example.com.conf.
The un-named segement in the data block means the current domain, like the @ used to mean.
