README ¶

CoreDNS-DN42

A CoreDNS plugin for serving the DN42 registry.

This plugin acts as an authoritative server. It returns NS & DS records for forward zones and reverse IPv4/IPv6 zones in DN42 registry. It doesn't do any recursion, you need a separate DNS resolver for that.

WARNING

This plugin is experimental. While it appears to work for forward and reverse IPv4/IPv6 DNS, it isn't fully compliant with DNS protocol specs. Compatibility with DNS clients isn't guaranteed.

Compilation

In your cloned CoreDNS repository:

Add dn42:github.com/xddxdd/coredns-dn42 to the end of plugin.cfg
go get github.com/xddxdd/coredns-dn42
go generate
go build

Usage

. {
  dn42 "/path/to/dn42/registry" 900
}

First argument (mandatory) is the path to DN42 registry. Inside the registry path, there should be a data folder containing all IPs and domains.

Second argument (optional) is the default TTL. If unset, default TTL is 3600.
