I found its internal working quite interesting: $ dig 127.0.0.1.xip.io ;; ANSWER SECTION: 127.0.0.1.xip.io. 403 IN CNAME 9zlhb.xip.

Apparently, 9zlhb is a base 36 of integer of 1.0.0.127. ip: 1.0.0.127 dec: 16777343 base 36: 9zlhb I guess they decided to reverse the IP address to make generated CNAME scale better (in number of characters): base 36 reverse base 36 1.0.0.0 9ZLDS 1 10.0.0.1 2RVXTT 9ZLE2 127.0.0.1 Z8KFLT 9ZLHB

The code is on github https://github.com/sstephenson/xipd/blob/master/src/index.coffee#l95-l99 https://github.com/sstephenson/xipd/blob/master/src/index.co.... I wonder if it was just an oversight in parsing the string, rather than deliberate.

There is http://nip.io http://nip.io as well, which does resolutions quite straight forward: $ dig 127.0.0.1.nip.io ;; ANSWER SECTION: 127.0.0.1.nip.io. 432000 IN A 127.0.0.1

  Hmm, this doesn't seem to be working for me in the same way that xip.io does. One of my favorite features of Pow (also 37Signals, mentioned on xip.io) is the ability to forward .dev domains to certain ports. For instance: `echo 3000 >> ~/.pow/myapplication` gives you `myapplication.dev` as an alias for `localhost:3000`. xip.io seems to be able to figure that out -- myapplication.10.0.0.1.xip.io will work, whereas myapplication.10.0.0.1.nip.io does not (just shows the Pow page you would see for going to `localhost`). Am I missing something here to get it to work with nip.io? I'm all for simpler tools, but since the port functionality is 100% of what I use Pow for, xip.io seems to be the way to go for now.

    Pow has a special support for .xip.io domain[1]. If you add `export POW_EXT_DOMAINS=10.0.0.1.nip.io pow` to `~/.powconfig` it should work[2]. I haven't tried this myself though.
