   Someone is selling a list of available three, four, and five letter .io domains that are available for $20. This - https://gist.github.com/4111298 - generates a list of available .io domains of any length (user specified). And, its free. (I'm away from my computer, so it isn't tested, but I ran it in repl.it). Edit - this is the seller - http://news.ycombinator.com/item?id=4804627

    Backname.io – every IP address gets its own domain▲46

    I was setting up tests involving DNS resolution recently, where something like 127.0.0.1.service.foo would have been tremendously useful. Back in the day, I'd have used xip.io - but sadly that service died. Well, every excuse is a good one when it comes to writing a DNS server! Backname.io joins nip.io and sslip.io in the wildcard DNS game.
