Email RFC List
RFC stands for Request for Comments. The term is very old, and reflects back to a time when the community of engineers who designed the architecture of the Internet was much smaller and more intimate. For all practical purposes, you could think of an RFC as a document that describes a protocol specification that relates in some way the Internet.
