## About

Dead simple wildcard DNS for any IP Address

nip.io allows you to map any IP Address in the following DNS wildcard entries:

It works with Dashes `-`, perfect for wildcard TLS certs:
~~~
10-0-0-1.nip.io maps to 10.0.0.1
app.10-0-0-1.nip.io maps to 10.0.0.1
customer1.app.10-0-0-1.nip.io maps to 10.0.0.1
~~~

As well as Dot `.`:
~~~
10.0.0.1.nip.io maps to 10.0.0.1
app.10.0.0.1.nip.io maps to 10.0.0.1
customer1.app.10.0.0.1.nip.io maps to 10.0.0.1
~~~

See https://github.com/resmo/nip.io/blob/master/src/backend.conf.example for an example config-

**Hint**: See the static CNAME `_acme-challenge=xyz.auth.example.com.` in the example, use it with https://github.com/joohoi/acme-dns for free Let's Encrypt TLS certs.
