RE: FW: [dhcwg] co-existence of temp and normal addressesThis idea is ok.
But, we need two types of IA options : Renwable IA and Non-Renewable IA,
because, T1 and T2 fields doesn't make sense, if IA contain temporary
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)
          ...

  - Bernie

  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.

  Thomas
