Of course you can. > Even though the RFC states that the prefix is fe80::/10 it really should be > fe80::/64. Section 2.5.6 of RFC3513 explicitly states that the 54 bits following > 1111111010 should be set to 0 and thus the only allowable prefix is fe80::/64. The contents of the 54 bits are only a should, as such one can use whatever one wants in there. Nothing breaks (wrt normal LL address usage) if those 54 bits have non zero values. Certainly a given platform shouldn't object to finding non zero values in a LL packet it receives (e.g. say a src address of fe80:1910::10).
