Mapdns Save

A simple, static DNS server.

Project README

mapdns CI

A smol DNS server (around 100 loc) that's configured with a static JSON file. Useful for split-dns.

Install

Go

go install github.com/bahlo/[email protected]

Docker

docker pull ghcr.io/bahlo/mapdns:0.2.0

Example

Create a mapdns.json in the same directory you're running the binary from, with content like this:

{
	"foo.example.org.": {
		"A": "1.2.3.4",
		"AAAA": "::1"
	},
	"*.foo.example.org.": {
		"A": "1.2.3.4"
	}
}

Run the binary and start making requests!

State of the project

It works and I use it in my home network for split-dns[^1]. There is little tests and no support for records other than A and AAAA. Please don't use this on a production system.

Logging

Expose MAPDNS_DEBUG=true to get debug logs. Otherwise it will only log on errors.

[^1]: I use Tailscale and configured it to search for my internal network domain on the DNS server I configured here.
