Mike,  I did an IPv6 presentation a few years ago.  You can get the PDF
at <www.wmmi.net/documents/BasicIPv6.pdf>.  If it would be useful I can
send you the source document [ODP].

Yep,  MAC addresses are just as important in IPv6 as in IPv4,  but
important differently.

I still find IPv6 vs. ARP to be a strange thing.

And why so many apps crash - they assumed network addresses of a certain
length or data-type [as some databases have ipv4-addr like data types...
BOOM!]
