Hi Tim,
I think what I am suggesting is a two track program. I think Bill is
right in pursuing the issue with IPv6. I just think that the issue will be
with us in the IPv4 world for a while.
For what it's worth, even when new IPv4 address space is exhausted,
that does not meant that it is going away.
Mike

We serve the research community in Europe. Our backbone, and those of most
of our customer networks (European NRENs) are fully v6 compliant. Our
routers typically have two v4 and two
v6 loopback addresses. We would certainly want one icon for the device, and
to be able to poll differentially with different probes.
I would even like to be able to have the ants represent v6 traffic rather
than v4.

While this is true, the fact is that the Internet "powers" seem to be
thinking that v4 space will be exhausted in between two to four years. That
spells trouble for when the registries have no more v4 space to hand out.
I think most desktops are ready (it seems easy to configure my Mac for v6),
but I would say that ISPs should be gearing up for this, and expecting that
support tools be nice and flexible when it comes to running a hybrid
network, which is probably what
will happen for a while.
Looks like I'm supporting Bill's proposal.
