A Request For Comments (RFC) document defines a protocol or policy used on the Internet. An RFC can be submitted by anyone. Eventually, if it gains enough interest, it may evolve into an Internet Standard. Each RFC is designated by an RFC number. Once published, an RFC never changes. Modifications to an original RFC are assigned a new RFC number.
