RFC stands for Request for Comments, which is a type of document published by the Internet Engineering Task Force (IETF) and other organizations involved in the development of the Internet and its technologies.
A Request for Comments (RFC) is a publication from the Internet Society (ISOC) and its associated bodies, most prominently the Internet Engineering Task Force (IETF), the principal technical development and standards-setting bodies for the Internet.
RFCs are used to propose new standards, protocols, or technologies, or to provide information about existing ones. They are typically written by individuals or groups of experts in the field and are made available to the public for comment and review.
RFCs can cover a wide range of topics, including networking protocols, security standards, programming languages, and more. They are usually numbered sequentially and often referred to by their number, such as RFC 791, which defines the Internet Protocol version 4 (IPv4).
RFCs are an important part of the open standards process for the development of the Internet and its technologies, and they have helped to establish many of the standards and protocols that are used today.
An RFC is authored by individuals or groups of engineers and computer scientists in the form of a memorandum describing methods, behaviors, research, or innovations applicable to the working of the Internet and Internet-connected systems. It is submitted either for peer review or to convey new concepts, information, or occasional engineering humor. The IETF adopts some of the proposals published as RFCs as Internet Standards. However, many RFCs are informational or experimental in nature and are not standards. The RFC system was invented by Steve Crocker in 1969 to help record unofficial notes on the development of ARPANET. RFCs have since become official documents of Internet specifications, communications protocols, procedures, and events. According to Crocker, the documents “shape the Internet’s inner workings and have played a significant role in its success”, but are not well known outside the community.
Requests for Comments are produced in non-reflowable text format, but work has begun to change the format so that documents can be viewed optimally in devices with varying display sizes.
Outside of the Internet community, other documents also called requests for comments have been published in U.S. Federal government work, such as the National Highway Traffic Safety Administration.
There are nearly 8700 RFCs available now. To know more about RFC (Request for Comments) visit the following IETF web page. https://www.ietf.org/standards/rfcs/
