Hi all,
The request for multiple probes on one device is almost as old as IM
itself! I can remember making the request in 1995.
Bill, while IPv6 should have this from the start and I applaud you
for moving ahead with this, IPv4 will be with for far longer that some at
the IETF would like. I know of not a single commercial enterprise that my
company serves that has both hardware and software fully IPv6 compliant.
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.
In many cases their routers or edge facing firewalls are not fully IPv6
complaint at this time. As a direct provider to such corporate networks, we
have yet to understand the benefit to us of adding IPv6 to our routing.
[Over the years as we have grown in customers, customers are
requesting smaller IP assignments. In fact we have had customers who have
returned IP to us. We are operating under the same IP allocation from ARIN
1999 and still have IP unassigned. While we do not have an excess of such
IP, we do not have any immediate needs for increasing allocation space.]
I suspect we are all still some years away from true ubiquitous IPv6
networks.
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.
