rdns-go

rdns is a reverse DNS proxy resolver written in Go. It acts as a DNS server, forwarding DNS queries to configured nameservers and returning the corresponding reverse DNS records.

Building

To build the rdns-go project, you need to have Go installed. Follow the official Go installation instructions for your operating system.

Once Go is installed, clone the rdns-go repository:

git clone https://git.rznet.fr/razian/rdns-go
cd rdns-go

Build the rdns binary:

go build

This will create a rdns binary in the project directory.

Usage

The rdns-go project can be started using the provided docker-compose.yml file. Modify the environment variables in the docker-compose.yml file to customize the configuration.
