IKEv1 [RFC2409] and its related documents for ISAKMP [RFC2408] and IPsec DOI [RFC2407] were obsoleted by IKEv2 [RFC4306] in December 2005.  IKEv2 has now seen wide deployment and provides a full replacement for all IKEv1 functionality.  No new modifications or new algorithms have been accepted for IKEv1 for at least a decade.  IKEv2 addresses various issues present in IKEv1, such as IKEv1 being vulnerable to amplification attacks. It is therefore timely to mark these IKEv1 specifications as Historic.

Upon approval and its publication as an RFC, draft-ietf-ipsecme-ikev1-algo-to-historic should replace this status change document as the reference for the status change event.
