So… these aren't accessible without specially configured DNS, right? Given that the point of domains is to let people get to your site, a TLD only accessible after reconfiguring your computer to use a little-known DNS competitor seems worth a hell of a lot less than $19,000.

Yeah...this basically ignores those totally minor perks like “SEO” and “people can actually find your site.” Unless I’m missing something here.

smells like new.net

This is spam.
