IANA has a list of reserved domains, in tests and documenation. Most famous are probably example.com and example.org.

For documentation and designs of a system that uses very short URLS, I'm looking for a t.co or bit.ly equivalent. I could not find any short ones on that IANA resource.

What is the shortest possible, offical "example" or "reserved" domain and therefore URL?

The document you refer to refers to RFC 2606 that lists all reserved domains that are four TLDs:

     .test
     .example
     .invalid
     .localhost

and three second level domains:

    example.com
    example.net
    example.org

The shortest of them is .test TLD.

Domains like t.co and bit.ly are real domains with single letter second level domain and regular to letters TLD.

  • From that, I understand that e.test would be a valid test domain, comparable to example.com or example.org? – berkes Oct 27 '20 at 10:03
