   KittenDNS – Easy to setup, rule engine, LetsEncrypt compatible▲107

   My goal was to create a DNS server as simple as the LDAP server I've been contributing to (glauth) and here it is: https://github.com/fusion/kittendns A few things to know about it: - It is easy to configure using a Toml file - I am using it to bail my coredns/etcd instances when under attack - (yes, it also works as a service location server) - It comes with a simple, plain English, rule engine that doesn't do much at this point - It can be used with LetsEncrypt. I use it to retrieve certificates for my home servers. - RFC: all the nice ones :) Anyway, feedback is…

    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.
