xip.name

A simple wildcard DNS inspired by xip.io

        10.0.0.1.xip.name  resolves to  10.0.0.1
    www.10.0.0.2.xip.name  resolves to  10.0.0.2
    foo.10.0.0.3.xip.name  resolves to  10.0.0.3
bar.baz.10.0.0.4.xip.name  resolves to  10.0.0.4

        10-0-0-5.xip.name  resolves to  10.0.0.5
    www.10-0-0-6.xip.name  resolves to  10.0.0.6

How does it work?

xip.name runs a custom Domain Name Server which extracts any IP address found in the requested domain name and sends it back in the response.

Does it cost anything to use xip.name?

No, but you are welcome to donate if you find the service useful.

Credits

xip.name is built on top of Miek’s lovely dns package for Go.

Lars Wilhelmsen made some tiny improvements and added a Dockerfile to produce an Alpine-based image hosting xip and website (on nginx) + support for configurating xip via environment variables.

Overview

xip.name is a small name server which sends back any IP address found in the provided hostname.

When queried for type A, it sends back the parsed IPv4 address. In the additional section the client host:port and transport are shown.

Basic use pattern:

dig @xip.name foo.10.0.0.82.xip.name A

; <<>> DiG 9.8.3-P1 <<>> @xip.name foo.10.0.0.82.xip.name A
