xip.io - Access any dev App via internal IP using a magic domain

http://xip.io (update: now seems dead)

What is xip.io?
xip.io is a magic domain name that provides wildcard DNS
for any IP address. Say your LAN IP address is 10.0.0.1.
Using xip.io,

      10.0.0.1.xip.io   resolves to   10.0.0.1
  www.10.0.0.1.xip.io   resolves to   10.0.0.1

mysite.10.0.0.1.xip.io resolves to 10.0.0.1
foo.bar.10.0.0.1.xip.io resolves to 10.0.0.1

...and so on. You can use these domains to access virtual
hosts on your development web server from devices on your
local network, like iPads, iPhones, and other computers.
No configuration required!

@robi Cool concept. What’s the benefit over just using the IP though?

Through sni you can host multiple websites on the same ip.

@robi Do you know if Let's Encrypt certs work with those domains (since LE has limits). Or maybe they have some special agreement with Let's Encrypt to get over the rate limits?

@girish they resolve to a local IP, so I don't really see how the letsencrypt verification procedure could find your server. Or am I missing something ?

[girish]

@mehdi I think you can put any public IP as well. So you can create a droplet and use it's public IP address.

Any IP is usable not just private ones. Hence yes, you can get a LE cert.. try it.

I don’t understand how tho if no two of these “magic domains” can point to the same IP?

I think I may have a use case for this then! wonder if I could get a wildcard cert for it.

From the projects homepage:

10.0.0.1.xip.io resolves to 10.0.0.1
www.10.0.0.1.xip.io resolves to 10.0.0.1
mysite.10.0.0.1.xip.io resolves to 10.0.0.1
foo.bar.10.0.0.1.xip.io resolves to 10.0.0.1

So multiple domains can point to the same ip.

@fbartels Ohhhhhh. I understand now. Thanks for the explanation. What a cool concept.

[robi]

bumping for a refresher.

[rmdes]

@robi main domain seems to be dead ?

[BrutalBirdie]

@rmdes there is also https://nip.io/

nip.io maps <anything>[.-]<IP Address>.nip.io in "dot", "dash" or "hexadecimal" notation to the corresponding <IP Address>:

dot notation: magic.127.0.0.1.nip.io
dash notation: magic-127-0-0-1.nip.io
hexadecimal notation: magic-7f000001.nip.io

The "dash" and "hexadecimal" notation is especially useful when using services like LetsEncrypt as it's just a regular sub-domain of nip.io
