# NIP.IO

[![Build Status](https://travis-ci.org/exentriquesolutions/nip.io.svg?branch=master)](https://travis-ci.org/exentriquesolutions/nip.io)

Dead simple wildcard DNS for any IP Address.

[NIP.IO](http://nip.io) is powered by [PowerDNS](https://powerdns.com) with a simple,
custom [PipeBackend](https://doc.powerdns.com/authoritative/backends/pipe.html):
[backend.py](nipio/backend.py)

Head to [NIP.IO](http://nip.io) for more details.

NIP.IO is licensed under [Apache 2.0](LICENSE.txt), and is a free service run by
[Exentrique Solutions](http://exentriquesolutions.com)

## Environment Variables Configuration Overrides

While all configuration settings can be specified in a file called [backend.conf](nipio/backend.conf), the following
environment variables override those:

`NIPIO_DOMAIN`: NIP.IO main domain.

`NIPIO_TTL`: Default TTL for  NIP.IO backend.

`NIPIO_NONWILD_DEFAULT_IP`: Default IP address for non-wildcard entries.

`NIPIO_SOA_ID`: SOA serial number.

`NIPIO_SOA_HOSTMASTER`: SOA hostmaster email address.

`NIPIO_SOA_NS`: SOA name server.

`NIPIO_NAMESERVERS`: A space-separated list of domain=ip nameserver pairs. Example: `ns1.nip.io=127.0.0.1 ns2.nip.io=127.0.0.1`.

`NIPIO_WHITELIST`: A space-separated list of description=range pairs for whitelisted ranges in CIDR format.
An IP address must be in one of the whitelisted ranges for a response to be returned. Example: `whitelist1=192.168.0.0/16 whitelist2=127.0.0.0/8`.

`NIPIO_BLACKLIST`: A space-separated list of description=ip blacklisted pairs. Example: `some_description=10.0.0.1 other_description=10.0.0.2`.

This is useful if you're creating your own [Dockerfile](Dockerfile).
