The Internet Engineering Task Force (IETF) is an open international community of network designers, operators, vendors, and researchers concerned with the evolution and operation of the Internet. It is responsible for developing and promoting voluntary internet standards, known as Request for Comments (RFCs), which encompass various protocols, technologies, and best practices for the functioning of the internet.

The IETF operates through working groups, where experts collaborate to address specific internet-related issues and develop or revise protocols and standards. These working groups cover a wide range of topics, including network protocols, security, internet governance, and many others.

The IETF holds multiple meetings throughout the year, known as IETF meetings. These meetings provide a platform for participants to discuss, design, and coordinate the development of internet standards. The meetings are typically numbered sequentially, such as IETF 112, IETF 113, and so on, and they take place in various locations around the world.

IETF meetings consist of working group sessions, plenary sessions, Birds of a Feather (BoF) sessions, and other activities, and they play a crucial role in shaping the future of the internet by fostering collaboration and consensus among experts in the field. The IETF website provides up-to-date information on the organization's activities, meetings, working groups, and standards development.
