In early 1996, the IAB published a short RFC entitled "Renumbering Needs Work" [RFC1900], which the reader is urged to review before continuing. Almost ten years later, the IETF published "Procedures for Renumbering an IPv6 Network without a Flag Day" [RFC4192]. A few other RFCs have touched on router or host renumbering: [RFC1916], [RFC2071], [RFC2072], [RFC2874], [RFC2894], and [RFC4076].
