DIY: The Internet

When I used to go to NYU, I assisted in teaching a web class to graduate students. There was one woman in the class who was amazed that I was able to publish her information to the Web so quickly! She thought the Internet was a black box somewhere and that I had to ask permission to put stuff onto it.

Well now you can make your very own black box of Internet, courtesy of the IT Crowd. You can loan folks the Internet but remember to return it to a high tower where it can get the best reception.

Actually all this is is a box with an LED on it. However, do tell us if you’re able to convince anyone that you’ve given them the actual Internet. We’d love to hear about the resulting guffaws.


Tablet makers rethinking things in wake of iPad's low price

Competing tablet makers are reevaluating their pricing strategy in the wake of Apple's iPad announcement, according to a rumor in the Digitimes. The article cites the usual unnamed sources in claiming that companies like ASUS and MSI had expected Apple's iPad to debut at $1,000, and were planning to undercut that price by 20 to 30 percent with their own, presumably Android-based offerings. But with the iPad base model coming in at $499—the price of a decent netbook—the companies are now going to have to compete on something besides price.

Assuming this rumor is true, and it seems completely plausible, then it confirms what a major shift in strategy the iPad is for Apple's business. Apple jealously guards its fat margins, but those margins are almost certainly taking a major hit to get the base model iPad out the door at this price point. This sacrifice is an acknowledgment by Apple that it has to go out and create a market for a device that people don't yet know they need.

The iPad's price is also another sign of just how massive an impact that the netbook has had on the business of computing. If Apple is sacrificing profits to make the iPad an alternative to the netbook as a second or third computer for mass-market use, then Apple can join Intel, Dell, HP, and other PC vendors in the list of companies that have seen their margins suffer due to the netbook's popularity.

How did they get the price so cheap?
The inevitable teardowns haven't been done yet, but even now it's hard to see how Apple will make much, if any, money on the $499 model. This being the case, it's worth considering how the company can afford to launch at this price point.

The first trick that Apple used to keep the cost down is that, as many have pointed out, the iPad left out some key hardware features and will instead charge users a nice markup on accessories designed to give those features back. Specifically, the lack of built-in USB ports and SD card support saved a few dollars per unit, and for a unit that will eventually sell in the tens and possibly of millions, that's real money. And Apple makes even more money if it can sell tens of millions of plastic USB and SD card adapters at a hefty profit.

Apple's second technique for mitigating the impact of that low price is the classic up-sell. The company is charging considerably more for the 3G and/or more storage, with the result that buyers of the higher-end models are pitching in extra money to pay for the low-end model's discount.

Finally, it's likely that Apple sees itself taking a page from the console makers' playbook by making up lost hardware revenues with content sales. Right now, prior to the advent of the HTML5 spec, which will make it much harder for Apple to take a cut of software and content distribution on the platform, Apple can afford to give away the hardware because it's taking a cut of iTunes, App Store, and iBook sales.

As Apple's iPhone OS inevitably begins to lose control of software and content distribution on the iPad to the browser, it's hard to see how it will continue to reduce the price of the device. What seems more likely is that the company will leave its pricing structure largely intact while widening its margins as unit prices decline.

Comcast running out of IPv4 addresses, beginning IPv6 trial

Comcast is asking for volunteers to participate in its upcoming IPv6 trials. The cable ISP has been participating in IPv6 circles for a long time and with its huge subscriber base, it is experiencing the IPv4 address scarcity first-hand. So far, it has been able to get addresses for its customers—but not for those customers' cable modems and set-top-boxes. These also need addresses to function or to be managed. No problem, right? Just use private IPv4 addresses, such as the 10 network, which holds 16.8 million addresses. But with 25 million TV, 15 million ISP, and 6 million Comcast Digital Voice subscribers, 16.8 million private addresses isn't enough for a regular management system in which a management station can directly connect to each managed device. So Comcast needs IPv6 just to run its internal network effectively now.

We're also running out of IPv4 addresses, so at some point in the future, Comcast will be unable to obtain additional addresses to connect new customers. So Comcast also needs to provide IPv6 service to its customers at some point and is looking for willing subjects to give it a try.

Comcast plans four trials. The first one will use a transition technique that is still under development, called 6RD. 6RD is similar to the 6to4 automatic tunneling mechanism that is available in Windows (it's enabled automatically when the system has a public IPv4 address under Windows 7 and Vista). The difference is that 6RD only tunnels IPv6 packets across an IPv4-only part of the service provider's network, while 6to4 can tunnel across large parts of the Internet, possibly incurring slowdowns.

The second trial will be with native IPv6. Here, IPv6 packets are transmitted across the infrastructure without encapsulating them in IPv4 packets. IPv4 remains available, creating a "dual stack" deployment. "Native, dual-stack is central to our IPv6 strategy and we expect that the native dual-stack solution will be a significant part of the IPv6 transition, enabling IPv6 technology to evolve globally while still being able to provide seamless services to the traditional IPv4 Internet," says Comcast.

The third trial will basically be the opposite of the first: rather than encapsulate IPv6 packets in IPv4 packets in order to traverse IPv4-only network sections, IPv4 is now encapsulated in IPv6 to get across IPv6-only parts of the service provider network. The technique for this will be "Dual Stack Lite," a protocol that is being developed in the IETF Softwires working group, which is co-chaired by Comcast's Alain Durand. In Dual Stack Lite, the IPv4 hosts use private IPv4 addresses. A home router encapsulates those in IPv6 packets, and a "carrier grade NAT" both decapsulates the packets and performs Network Address Translation so that a lot of DS-Lite clients can share a single IPv4 address.

The fourth trial will evaluate how to provide IPv6 to business class customers. The first two trials are scheduled for the second quarter of 2010, the other two for the third quarter. At this time the details on what participating in each trial will encompass are unclear, and signing up doesn't necessarily guarantee participation.
