If the "small network" is a single link, and if you just need one
address per host, then you can send an ICMPv6 echo request to ff02::1
and collect the source addresses of echo replies.
If the "small network" is a single link, but if you need all addresses
for each host, you could use IPv6 node information queries (described
in draft-ietf-ipngwg-icmp-name-lookups-09.txt). However, I suspect
that not many (types of) IPv6 implementations support this.
Of course, either approach is not 100% reliable, because queries and
responses may be dropped.
If the "small network" is larger than a single link, you can't do that
without some protocol extensions.
