Requests for Comment (RFCs)

The following tabulation lists all current (not obsolete) RFCs that have Usenet or NNTP in their titles along with selected RFCs to which they refer and some other RFCs of general Internet impact. Some (e.g., RFC1855) may be of interest to general newsgroup participants. Others (e.g., RFC2046) are of a technical nature that might be of interest only to developers of news servers and clients.

The RFC number in the first column is a link to its online document.

The term RFC means "request for comment". Technically, an RFC is thus not a standard. In many cases, however, an RFC is as close to a standard as we can get. On the other hand, some RFCs have indeed been elevated to official standards. Those are indicated with their numbers in bold and the number of the standard in parentheses with STD.

The "Date" column is the date (month and year) the RFC was published for comments.

Under "Impacts On and From Other RFCs", obsolete RFCs are in strike-out. Links are provided for non-obsolete RFCs that update the subject RFC.
