Well, not really just the enlarged address space! There do exist certain
other definite benefits of IPv6 like possible use of Flow Specifications in
the Flow Label, decreased processing delay at routers, greater flexibility
etc. This is not to say that the IPv6 is answer to all problems, but just
to signify the worth of the effort of those working on it.

On the other hand, some IPv6 advocates never stop beating the drums
for IPv6 QoS, multi-homing, and so forth and how the Millennium will
arrive with IPv6. I think the truth in both cases is not so simple
as either minor enhancment or dawning of a new age.
It is certainly regretful that there are some that go around touting
IPv6 as the solution to all problems. But if you listen carefully to
what many in the IPv6 community are saying, they are saying that IPv6
provides more addresses, and that that is *the* *main* *benefit*. The
other changes/benefits (simplified autoconfiguration, improved
mobility, tools to help with renumbering, etc.) while important, are
secondary.
IPv6 is only rationally justified as a modest but necessary
enhancement to IPv4,
I agree with this, and suspect that much of the core IPv6 community
does as well.
