Found an interesting header when doing some tests with mail filtering:

Arbor Networks found that almost nobody is using IPv6 (a peak of 0.012% to be exact). Not exactly shocking.
This is due to a chicken or the egg problem:

ISP’s don’t give out IPv6 addresses because the majority of their customers can’t handle it. Modern operating systems support IPv6, but these days most people use [...]

I turned on Wireless Multimedia (WMM) support the other day on my wireless network, figuring QoS for a wireless network would pretty much be a slam dunk. For those who don’t know, the four access categories it uses are:

voice
video
best effort
background

I was surprised to find, at least with the Netopia box that this actually resulted [...]

I’ve finally got just about all the network graphs I maintain using RRDtool rather than MRTG. I started doing this since MRTG isn’t good for graphing things with more than 2 sets of numbers. I started doing this because I wanted to track cable modem data. I figured while I’m at it, [...]

I’ve seen this in several sites over the past few days. Apparently Denon decided to put out a $500 Ethernet Cable (AK-DL1). Free shipping via Amazon. I’ll give you few minutes to laugh.
Hopefully your now under control. As pointed out in various places like Slashdot and all the links in the [...]

As I hinted last week, I graph a fair amount of data, since I find it pretty handy at times, not to mention just interesting to see in a pretty graph form. I’ve been doing this for years and it’s served me well.
One thing I really wanted to get going was monitoring the cable [...]

For the past several weeks, the cable modem has been getting more and more unstable. Having dealt with this before I knew the signal quality was pretty poor from looking at the stats. By using a different line that goes more direct, it made a real difference as the data below shows (sidenote: [...]

Yesterday the estimated world population passed 6,666,666,666. Interesting (though just coincidence) the estimated number of available IPv4 addresses was supposed to pass 666,666,666. Perhaps we are the beast?
An interesting thing to note is that the population is increasing at a very rapid rate. How long it’s sustainable before a Malthusian catastrophe is [...]

Last Friday (May 2), the data center where this site lives suffered a power fluctuation due to some tornado activity in the area. The actual outage (if there was even one) seemed to have been in the 5 minute ballpark based on various monitors. Apparently this somehow resulted in a routing problem resulting [...]

The Standard has a good writeup on how we accept less than stellar uptime for things that are becoming more and more valuable such as broadband.
Phone service is reliable because it’s mandated to be. There’s pretty strict rules regarding uptime. As a result it’s pretty good. The reason for this is that [...]
