There is an ongoing discussion in BEHAVE ml, where it seems that we could use the "g" bit in order to include hash information... considering that the hash length is one of the key limitations of CGAs, we may consider updating 3972 to use this bit... comments? I attach the extract of the thread below... -------- Mensaje original -------- Asunto: [BEHAVE] Modified EUI-64 format Fecha: Thu, 2 Jul 2009 04:06:21 +0000 De: Dave Thaler <dthaler@windows.microsoft.com> Para: Xing Li <xing@cernet.edu.cn> CC: Behave WG <behave@ietf.org> Similarly, with privacy addresses referred to in the draft quote at top, RFC 3041 section 3.2.1 point 3 forces the randomized interface identifier to adhere to this requirement, so that it's a 63-bit random number, not a 64-bit random number. And with CGAs, RFC 3972 section 4 point 6 similarly forces a generated interface identifier to adhere to this requirement. (As an aside, it also reserves the "g" bit which is actually unnecessary since it's not IEEE EUI-64-derived. RFC 4291 only discusses the "g" bit for addresses derived from IEEE EUI-64's, which is why RFC 3041 and a translation format can still use that bit).
