I am interested in home network of course using of IPv6. When I thought a definition of IPv6 node, I separated two kinds of nodes, one is "active IPv6 node" which need to communicate another node and bidirectional connection the other is "passive IPv6 node" which is just controlled not try to access another node and unidirectional connection As you said below, thermometer is only passive node, therefore it is not need DNS resolving. IPv6 node is very very widely, then almost possibility must be considered not only PC or laptop... e.g. active IPv6 node : almost pc, laptop, PDA, hand-held devices, passive IPv6 node : thermometer, lighting, washer, refrigerator, some kinds of home appliances

I > am confusing "MAY" When above node is fail to obtain stateless address > autoconfiguration, if node didn't have Stateful AA function, it is > impossible to make each own address. so I think "Should" is better. In what cases will stateless address autoconfiguration fail? If it fails, there is always the possibility of setting addresses by user interaction (typing in the addresses). Stateful is dependent upon DHCPv6, and users cannot depend that it will be implemented everywhere, especially since it is not a standard yet. > 4.6.1 > This section is more related mobileip, not general IPv6 node > requirement. MobileIP is actually considered as part of IPv6, but I get your point. This I could move into the MIP section. > 5.2 "...

Some nodes will be servers only and only accept incoming requestions. Think of a thermometer with an IPv6 stack. It will never need DNS. > in addition, as 1.2, Desctiption of an IPv6 node is so ambiguous. In > this draft, almost requirement is for general node which is pc, laptop > and that kind of thing.

It is ambiguous for a reason, as an IPv6 node is anything with an IPv6 stack - cell phone, laptop, server, IPv6 thermometer (yes, someone makes one already) or any embedded device. If you have a better suggestion for a definition, I would be happy to review it.
