The Day the Routers Died

This cute song is about a serious issue.

The Web is technically part of the Internet, descended from Arpanet. Way back when the addressing protocol was established, they figured that 4 bytes were sufficient. After all, there were about 10,000 computers in the world, and 4 bytes is over 4 billion addresses. It was the standard. But as personal computers emerged, and then the web grew, it soon became clear that this legacy would be a problem. So in the 1990's, they set up a new standard, IPv6. But there are already more websites than available addresses. This is done by clumsily sub-networking most websites. But even with this, we are running out of addresses. So, why don't Internet providers simply switch? Much like why we are still using the clumsy QWERTY keyboard standard, designed to patch around a technical problem that was fixed over 100 years ago. The routers are used to the old standard, and are expensive to change. Part of the pain is that the new protocol is completely different, so a router has to handle both and be able to translate between. But change they must. As of this month (February 3, 2011), every old IPv4 address has been assigned. There are no more. And networks that have not yet upgraded to the 1998 IPv6 standard will not be able to see new websites. Thus the old routers must die. Most of us are protected in a subnet, as on a home or office network re-routed from a T1, cable, or DSL connection. But your computer still needs to be able to handle the new addresses to let you see external sites that are no longer using the older protocol.

Left Behind by Snowmageddon

There was recently a big winter storm across the Central and North Eastern U.S. In my local town, it had the potential of exceeding the record one-day snowfall set 29 years ago. All the local news stations talked about the major storm approaching. Thunder snow, a rare occurrence here, was predicted. Stores were stripped of snow shovels, salt, water softener (salt), milk and bread.The governor called in the National Guard, and all the utility and road crews were on high alert. When the freezing rain started on Monday, the media warned people to stay home for the next day or two as the storm passed over. I grew excited. The little kid in me was hoping for a big snow. But our town was right on the freezing line. Just south of us, there is rain. North of us, snow. The band from rain through freezing rain, sleet, snow, up to full blizzard is only a hundred miles wide. As Tuesday dawned, we had a glaze of ice, and sleet was falling. I woke early and spent a couple of hours learning how to hack my new super-zoom camera to force it to take a time lapse picture series. I hoped to make a nice video of the yard disappearing under a foot or more of snow. So I set up my camera and started it early in the morning, when there was still just a glaze of ice on the path and plants. The day wore on. At noon I it was still just sleeting. I changed the batteries in the camera. By sunset, there was just a couple of inches of sleet. It was fun to walk on top of what looks like snow. But the yard is still visible. Had the freeze line been a couple of dozen miles farther south, that thin layer of sleet would have been about a foot of snow. What a gyp! So I let the camera run overnight, in hopes that we'd get some snow on the few inches of ice. But as Wednesday dawned, Groundhog Day, there was only a little more snow. Sure, the roads are all iced over, and icicles hang from everything. But this is a far cry from what the hue and cry of the media had us expecting. Granted, the next county over (and half the state) is snowed in. Interstate 70 is closed between the Saint Louis metro area and Kansas. And the temperature will drop below zero (-18°C) tonight. But how did we get Left Behind from the transcendental fairyland, a heaven of deep snow? Obviously we hadn't prayed hard enough to the God of the clean white snowy world above to deliver us from mundane weather. Or we didn't believe sincerely enough in the snowy salvation offered by his half-breed son, Jack Frost. Maybe some around us are heretical worshipers of the Daily Commute, and counteracted our prayers. So we beseech those who were called up to the snowy realm to share with us their good fortune. Show us unworthy shovelers of sleet what the True Light of real snow is like. Maybe it's not too late.
