Do Not Track on the Web

Mozilla's Firefox plans to be the first Internet browser to offer a feature supporting the Federal Trade Commission's (FTC) call for a web-based do-not-track list, similar to the familiar do-not-call list.

Naturally, for this to work, tracking companies must agree to honor it. Not too surprisingly, no tracking company has publicly agreed, though Mozilla is urging them to join. Microsoft said it would revive privacy features (previously left out of MSIE) when Internet Explorer 9 is released.

Google also has similar tools in its Chrome browser, all of which currently rely on a brute-force approach of maintaining a local list of sites to block, whereas the do-not-track list would be something the trackers would agree to honor (by not tracking you) when presented to them by a browser.

Insufficient Addresses
This is a true and looming problem. Folks have been working on it for several years, and it's still several years away from full implementation.
The Internet is running out of addresses. When you type the familiar web address into your browser, it gets translated by root servers into a number. www.photosource.com becomes 74.208.112.83, for example. Well, there are only 4,300,000,000 possible addresses with this system, and, as with area codes, many are reserved. Like the hard disks of yore, when first envisioned, that was a pretty big number. Now, with so many devices wanting their own IP address, the world will run out of IPv4 addresses (as this system is called) very soon.
So, a new system, called IPv6 has been invented with much longer IP addresses that use numbers and letters (up to the letter f, as in Hexadecimal notation).

What's it all mean? Well, you add to your home office with network gear upgrade (or even buy new networking gear) that can process the new IPv6 notation.

You can do a test now. Many big companies have been slowly upgrading their websites and networks to support IPv6. Facebook has an IPv6 website at www.v6.facebook.com, which can only be accessed by systems that can support IPv6. So, type that URL into your browser and see if you get Facebook or an error.
