Hints and Tips and Tricks

Quickly install DiG on Windows without a full BIND9 install

Today I needed to use - and install - DiG (Domain Information Groper!) on a Windows 10 box. Of course, Windows is useless when it comes to CLI tools - nslookup is past its prime and not even Windows 10 includes much by way of useful tools for DNS queries.
