Informational RFCs

Informational RFCs (Request for Comments) are official documents published by the Internet Engineering Task Force (IETF) that provide valuable insights, guidelines, or context about internet technologies and standards. Unlike standards-track RFCs, which define mandatory protocols, informational RFCs share knowledge, best practices, or historical background without setting official rules. They serve as a reference for developers, engineers, and researchers to better understand complex topics related to the internet's development and operation. In essence, they help improve communication and understanding within the technical community without dictating specific technical requirements.
