Saw that earlier.  Tried disabling the interface, changing the suffix
of the iaprefix line in the lease file from /64 to /60, and
re-enabling it but the packet capture doesn't look any different. That
doesn't make any sense now that I think of it.  I expect to see it
request the addresses from the existing leases file.  Still digging...
