<p>Is anyone on this list planning on doing something special for v6 day? Either participating as a web site or doing some IPv6 enabling on the ISP side?</p>
<p>For our part, BBN will be enabling v6 on <a href="http://www.bbn.com">www.bbn.com</a>, and doing some measurements.</p>
<p>Best,<br>

<span style="font-size:14.0pt;color:black">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></p>

<span style="font-size:14.0pt;color:black">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></p>

<span style="font-size:14.0pt;color:black">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></p>

IPv6, your entire subnet will be directly connected to the Internet.</span></p>
