Dynamic Client IP matcher for Caddy

The dynamic_client_ip module is a clone of the client_ip matcher with one key difference: instead of providing IP ranges upfront, you specify an IPRangeSource. This allows IP ranges to be dynamically loaded per request.

Installation

Build Caddy using xcaddy:

xcaddy build --with github.com/tuzzmaniandevil/caddy-dynamic-clientip

Usage

:8880 {
	@denied dynamic_client_ip my_dynamic_provider
	abort @denied

    reverse_proxy localhost:8080
}

Example using the built-in static provider (But why though?)

:8880 {
	@denied dynamic_client_ip static 12.34.56.0/24 1200:ab00::/32
	abort @denied

    reverse_proxy localhost:8080
}

Development

Before diving into development, make sure to follow the Extending Caddy guide. This ensures you're familiar with the Caddy development process and that your environment is set up correctly.
