nametoip

nametoip is a plugin for CoreDNS that returns IP addresses encoded in hostnames. It is intended for local development, home labs etc... It provides functionality similar to services like nip.io and sslip.io.

It provides the following encodings:

• Dot notation. eg:
  • 10.2.3.4.example.com resolves to 10.2.3.4
• Dash notation. eg:
  • 10-2-3-4.example.com resolves to 10.2.3.4
• Hex notation. eg:
  • 0a020304.example.com resolves to 10.2.3.4
• Above encodings allow for arbitrary prefixes and subdomains. eg:
  • a.big.hello-world-10-2-3-4.example.com resolves to 10.2.3.4

For now, only private IPs are supported as this plugin is intended to support scenarios such as home labs, local development etc...
