Using example domains

If you ever find yourself writing documentation and want to specify an example domain, you might do jdoe@domain.com for example, right? Well as it turns out, there actually are IANA-approved domains just for this use. Here is the doc – it’s RFC 2606

Basically, it reserves the top-level-domains (TLD) of:

  • .test
  • .example
  • .invalid
  • .localhost

and for actual full domain names, it reserves:

  • example.com
  • example.net
  • example.org

Per this page on IANA, it says: “These domains may be used as illustrative examples in documents without prior coordination with us.”
