RFC Errata
Published RFCs never change. Although every published RFC has been submitted to careful proof reading 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.
