The Internet Engineering Task Force (IETF) is an organization that develops and promotes voluntary internet standards, particularly those related to the Transmission Control Protocol/Internet Protocol (TCP/IP). It consists of a large community of engineers, developers, and researchers who collaborate to improve the functionality and interoperability of the internet.
IETF operates through a series of working groups, each focusing on specific topics such as security, routing, and applications. The results of their work are published as Request for Comments (RFC) documents, which serve as guidelines and standards for internet technologies and protocols.
