Hi,

Before the sanitary situation I was studying an issue at ISO.

The issue is about 64bit MAC addresses and SLAAC.

SLAAC needs a 48bit MAC addresses in order to work, and it can not work 
with a 64bit MAC address; (but yes, it can with 64bit IIDs).

The document ISO/CD 22738:2019(E) under development at that time does 
specify a 64bit MAC address for optical camera communications (OCC, akin 
to IEEE 802.15.7).

This might be an additional requirement for SLAAC improvements.  Or not.

Alex
