Dead simple wildcard DNS for any IP Address.
NIP.IO is powered by PowerDNS with a simple, custom PipeBackend: backend.py
Head to NIP.IO for more details.
NIP.IO is licensed under Apache 2.0, and is a free service run by Exentrique Solutions
While all configuration settings can be specified in a file called 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.
