RE: FW: [dhcwg] co-existence of temp and normal addresses

Thomas/Vijay:

We did discuss this for a long time in designing the current DHCPv6 draft.

It really would have been useful if the IPv6 community has a means to classify the 'type' of an address. This would be useful for applications when they want to "find" a specific address.

Anyway, if we had such a thing, we would have revised the IA Option to carry it.

Though I hate to do it because it reopens the discussions, if we consider anything we shouldn't add more IA types. Instead, we should redesign the IA option slightly and add a type field. The type field (8 bit?) could have the following values:
	0	-	"Normal" addresses
	1	-	"Temporary" addresses
	2	-	"DSTM" addresses (this replaces the DSTM option)
	...

Hi Vijay.

I agree that you've raised a valid issue.

> - Why can't we have separate IAs for normal and temporary addresses?

Mixing temporary and non-temporary addresses in the same IA seems like
it may create some problems. I suspect that NOT mixing them together
within the same IA will simplify some things. I'll have to think a bit
more about the rest of your proposal.
