What is this?

I got fed up of not having a really simple but reliable way to validate public DNS resolution code for things like the DNS resource in (@aelsabbahy’s) awesome server validation tool: goss.

Sure I could use things like google.com or other DNS addresses but I can’t guarantee that they won’t change or be advertised differently around the globe. The records below are controlled by me and won’t ever change. This is also a good exercise for me to get to grips with different DNS server software, logging, filtering, stress testing and protection / security.

Maybe eventually I’ll make some tools available to interact a bit more with DNS (like we need more?).
