Looking at this in context it doesn't make any sense to look for NetBIOS services in IPv6.  NetBIOS is an IPv4-only protocol that Microsoft has been trying to phase out for years.  There are no plans to extend it to IPv6 - IPv4 is the end of the road.  So scanning for it with v6 tools doesn't make sense.

No more E-mails for me before coffee...
