A better place to ask this might be at the IETF DHC WG
(http://www.ietf.org/html.charters/dhc-charter.html).
While the capability exists to put other options in IA_* and IAADDR
options, there are no documents that specify this. For example, one
could put options that are specific to a single address in an IAADDR
IAaddr-options field. Or, options specific to an IA in the IA_*-options
field.
But, there are no good reasons to do this today so nothing specifies
doing do.
Earlier drafts of what became RFC 4704 had specified placing the FQDN
option in either of these places to perhaps have different names for
each address. But the IETF DHC WG felt that that was far to complex and
not warranted for today's networks.
But, no one knows what the future will hold.

Hi,
I was going through the web and came across your very
informative web site on the DHCPv6 RFC 3315.
I am sure that you will be able to throw some light on
the questions that I have on the RFC itself.
The RFC mentions that the IA_*-options carries
"Options associated with this IA_*". After reading the
RFC its really unclear as to what options are valid in
the IA_*-options. Other than OPTION_IAADDR and
OPTION_STATUS_CODE can any other option be carried in
the IA_*-options field.
Similarly in the IAaddr-options field other than the
OPTION_STATUS_CODE can any other DHCP option be
carried in the IAaddr-options field.
Thanks any help/clue, documentation on the format of
OPTION_IA_NA, OPTION_IA_TA and articles on these lines
would be very help.
Regards,
Anu
