Hi HN,
I created a clone of xip.io using PowerDNS and a simple custom PipeBackend using a single Python script.
After the initial discussion[1] and the glaring DNS mistakes[2] done on xip.io, I spent about 5 hours this afternoon to create nip.io which does exactly the same thing, but without most of the DNS mistakes.
Feedback welcome!
Thanks
