This is a simple DNS caching server.
It uses this DNS library for sending/receiving DNS queries.
Currently it caches only A and AAAA queries. If it receives a different query - it acts as a forwarding DNS server without caching.
There is a json config file in config/config.json
By default it creates a log file and also logs to STDOUT
After installing, the server is run with go run main.go or with go build main.go; ./main
