<DIV><FONT face=Calibri>If an ISP gets calls on World IPv6 Day (W6D) from
subscribers complaining that Facebook, Google or Yahoo are not reachable, then
its likely misconfigured 6to4 or Teredo service that is falsely indicating a
public IPv6 address on the subscribers host computer or home
router.</FONT></DIV>
<DIV><FONT face=Calibri></FONT> </DIV>
<DIV><FONT face=Calibri>Thus the biggest challenge on W6D will be the
subscribers home access side, not the web servers side. This is due to
Windows, Linux and Mac OS preferring IPv6 connections over IPv4 if a
website has an IPv6 DNS record.</FONT></DIV>

L2TP that can work over existing IPv4 modems/CPEs.</FONT></DIV>

Either participating as a web site or doing some IPv6 enabling on the ISP
side?<o:p></o:p></P>
<P>For our part, BBN will be enabling v6 on <A

style="COLOR: black; FONT-SIZE: 14pt">Earlier this spring, as anticipated, the
last of the IPv4 address blocks was given to the regional Internet registries
that dole them out to ISPs and other corporations. Unlike many predictions
that go back dozens of years, we have run out of room. Yes, it will take
several months before the world is completely run out of address space, and
you might be able to find an unused Class C range here or there. But for the
most part, you need to get cracking on a transition plan for your company to
migrate towards IPv6 now.</SPAN><o:p></o:p></P>
<P style="LINE-HEIGHT: 18pt; MARGIN-BOTTOM: 12pt"><SPAN
style="COLOR: black; FONT-SIZE: 14pt">Of course, people have been saying this
for years now. I recall writing a humorous article back in 1992 or so where I
suggested that I start a brokerage service charging for unused address blocks.
While it has taken several decades, we have gotten to the point where the end
of IPv4 is near. And unlike the predictions for the Rapture, this is an actual
event that will need our attention.</SPAN><o:p></o:p></P>
<P style="LINE-HEIGHT: 18pt; MARGIN-BOTTOM: 12pt"><SPAN
style="COLOR: black; FONT-SIZE: 14pt">To highlight this situation, a group of
engineers under the auspices of the Internet Society have set aside next
Wednesday, June 8th, to test the new protocol for an entire 24-hour period.
Various Web properties will put up IPv6 versions of their sites for the day as
demonstrations. And several vendors have begun to assemble copious
instructions and advice to help IT network managers figure out their
plans.</SPAN><o:p></o:p></P>
