From Bradley Mitchell, your Guide to Computer Networking
A guest speaker at this year's Defcon network security conference criticized the security of IPv6 in a big way. Assuming the kinks get worked out, 10 years from now all of our IP numbering will be changed over to this new style of addressing. (True, you may have heard others say the same thing ten years ago, but this time it's for real.)

Is IPv6 a Security Nightmare?
One potential trouble spot with the protocol is its handling of ICMP (better known as ping) messages. But wait, there's more.

How Fast Will Your Internet Be in 10 Years?
You may think you have fast Internet service today. Or you may have resigned yourself to a future of agonizingly slow connections. In the U.S., at least, the range of Internet speeds available to homes varies greatly depending on location. Will it always be this way?

Next Up for Wireless - 3D Video
Streaming video over a wireless network is a challenging technical problem that requires both high bandwidth and low latency. So what could be harder than that? Try 3D video over wireless. Ten years from now we may be watching a lot of that, too.

How to Ping Something
Microsoft Windows, Mac OS X, and Linux provide command line ping programs that can be run from the operating system shell. Computers can be pinged by either IP address or by name. The examples shown are for IPv4... but you get the idea.
