Just like Internet RFC (Request for Comments), there exists/use to exist other Internet documents like:
- BCP (best current practices). See https://mirrors.de.sahilister.net/pub/rfc/in-notes/bcp/
- FYI (for your information). See https://mirrors.de.sahilister.net/pub/rfc/in-notes/fyi/
- IEN (Internet Experiment note). See https://mirrors.de.sahilister.net/pub/rfc/in-notes/ien/

PS - I mirror bunch of Internet stuff at https://mirrors.de.sahilister.net/pub/ which also lead to above findings :)
