In the Request For Comments (RFC), each TCP/IP standard document
is assigned a status that indicates whether the standard document is still being edited, it has already been elevated to
standard, etc.The For Your Information (FYI) designation means "for your information
" and is used for non-technical standards or descriptions of protocols. FYIs convey general information about topics relatedto TCP/IP or the Internet
. In RFC documents, For Your Information represents an informal status. For Your Information is also often used in e-mail, when the sender simply wants to inform the mail recipient of a fact without expecting a response.
