It should handle it; but I'd still want someone to check out various edge conditions and pathological cases. > If you're in the situation that you need lla (no dhcp server available), The presence or absence of a DHCP server is not a good indicator of the need or desire for LLA and/or mDNS. It is quite possible that the system is in a mixed environment where there are some systems which are LLA/mDNS only, others which are DHCP/static/unicast DNS only, and others which handle both. > you wouldn't know the default route right? I believe that there is a way to announce routing service via mDNS-SD; but I don't know the details. (I would be astonished to discover that the people who developed the zeroconfig design left that bit out...) -Pat
