Naah, this isn't what I'm looking for. The changes in this commit are a mis-reading of the RFC — good try, though! I'll give a more thorough explanation tomorrow.

[Ichimonji10]

Ok, so RFC 2606 states that the following domains are reserved:

• test
• example
• invalid
• localhost

Notice that those are all top level domains. That's the really important part: they're top level. Thus, these domains all fall under the scope of RFC 2606:

• omaciel.wordpress.example
• bad-ssl-certs.super-unsafe-site.invalid
• development-webserver.localhost
• fourth.third.second.test

However, the following do not fall under the scope of RFC 2606:

• example.biz
• invalid.com
• localhost.net
• test.com

This PR places example, invalid, localhost and test in the SUBDOMAINS list, which will produce domains of the second type. Those domains should go into TLDS, so as to produce domains of the first type.

All that said, com, net and org can be used as top-level domains. However, they can only be used as top-level domains if example is used as a second-level domain. Thus, the following are all valid:

• example.com
• third.example.com
• fourth.third.example.com
• fourth.third.example.net

… and so on.
