TIL, woops!

I use this for all my internal domains, haha. I guess this is why we need a proper tld like this.

You could consider making them real mDNS domains then, and using mDNS to resolve them to your desired IPs.

The following TLDs are fine and reserved:

                .test
                .example
                .invalid
              .localhost
