[RFC4862] specifies Stateless Address Autoconfiguration (SLAAC) for IPv6 [RFC2460], which typically results in hosts configuring one or more "stable" addresses composed of a network prefix advertised by a local router, and an Interface Identifier (IID) [RFC4291] that typically embeds a stable link-layer address (e.g., an IEEE LAN MAC address).

           Recommendation on Stable IPv6 Interface Identifiers


   This document changes the recommended default Interface Identifier    (IID) generation scheme for cases where Stateless Address    Autoconfiguration (SLAAC) is used to generate a stable IPv6 address.    It recommends using the mechanism specified in RFC 7217 in such    cases, and recommends against embedding stable link-layer addresses    in IPv6 IIDs.  It formally updates RFC 2464, RFC 2467, RFC 2470, RFC    2491, RFC 2492, RFC 2497, RFC 2590, RFC 3146, RFC 3572, RFC 4291, RFC    4338, RFC 4391, RFC 5072, and RFC 5121.  This document does not    change any existing recommendations concerning the use of temporary    addresses as specified in RFC 4941.
