You have IPv6, want to connect to some device and your router can't do mDNS or local domains?
Or, for whatever other reason, you want to be spared the pain of typing out an IPv6 address?
Then give-me-dns(.net) is just right for you!
Simply connect via a TCP client of your liking (like nc give-me-dns.net 9999) and you'll get a temporary DNS subdomain
Start the server: cd cmd/give-me-dns && go run ../../config.yaml
Get a name: nc localhost 9999
Query the DNS: dig -p5354 @localhost 1234.give-me-dns.net AAAA
