Published RFCs never change. Although every published RFC has been submitted to careful proofreading by the RFC Editor and the author (s), errors do sometimes go undetected. As a service to the readers of RFCs, this page contains a list of technical and editorial errors that have been reported to the RFC Editor and verified by the authors or the IESG.

In general, we cannot guarantee the correctness of these errata; the reader must make his/her own judgment.
