I’m not a fan of 37signals, but I must admit their DNS service xip.io is
handy. I’m setting up some web servers right now, and I needed a domain to test
my configuration. The whole DNS dance is a bit time-consuming: add record to
zone file, & wait for my DNS to pick it up. With xip.io there’s no need to wait:
prepend your host’s IP address before
.xip.io and the domain will resolve to
your own IP.
127.0.0.1.xip.io will resolve to
They are other services like this like ipq.co or localtest.me, but as far as I know they don’t work out of the box: you have to register your subdomain first or can only use it with localhost.
