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.

Install

As Docker Container

Run the Container from ghcr:

Quick test run with built-in config for example.com:

docker run -d -p 0.0.0.0:5353:53/tcp -p 0.0.0.0:5353:53/udp --name nip.io ghcr.io/resmo/nip-io:latest
dig @localhost -p5353 10-1-2-3.example.com

Provide your own config as volume:

docker run -d -p 0.0.0.0:53:53/tcp -p 0.0.0.0:53:53/udp -v /data/backend.conf:/usr/local/bin/backend.conf --name nip.io ghcr.io/resmo/nip-io:latest

Or Build the Image:

docker build -t nip.io .

See the Logs:

docker logs -f nip.io

Test it

dig 1-2-3-4.example.com +short @localhost
