wildcard-dnsd is a simple, standalone wildcard DNS service. It is very similar to nip.io, but is written in Ruby rather than Python, and does not require the deployment and configuration of PowerDNS.

Because sometimes you want a self-hosted alternative to nip.io, without the hassle, for reliability, network isolation, or other reasons.

gem install wildcard-dnsd

wildcard-dnsd [domain ...]

wildcard-dnsd requires very little (if any) configuration. Assuming it has sufficient privileges to bind a privileged port (53), the default behaviour is to bind to all interfaces and listen on UDP/53.

It uses the default DNS resolvers for your system, detected at startup.

If you prefer to bind to a specific interface, set FRONTEND_HOST in the environment. If you need to bind to a different port, set FRONTEND_PORT.
