John Gruber among others note that Google DNS service is not tied to Google Accounts. That’s not just wording in their privacy statement, it’s technically impossible for them to do otherwise, at least with reasonable accuracy.

Google Public DNS Analysis
Google’s new Public DNS is interesting. They want to lower DNS latency in hopes of speeding up the web.
Awesome IP Address
This is the most interesting thing to me. I view IP addresses similar to the way Steve Wozniak views phone numbers, though I don’t collect them like he does phone numbers.

Yahoo Traffic Server Open Sourced
Way back in 2002 Yahoo acquired Inktomi who was largely know for their search products. Their software powered some early search engines like HotBot in the pre-Google days. One of their lesser known products was something called Traffic Server. Even if it was lesser known it was still used by ISP’s including [...]
Remove Spikes From RRDtool Graphs
I use RRDtool to make graphs on various things I monitor like server stats, network stats and it does a relatively good job. My one (big) complaint is that when you restart you occasionally see these gigantic spikes that completely mess up the data. I’ve even seen spikes larger than what the system [...]
802.11n Finalized
802.11n, something I was starting to think would never get beyond draft is now approved. Having suffered through “compliant” 802.11b devices I long ago decided wireless networking is fussy enough to warrant stricter standards. As a result I stuck to Wi-Fi Alliance certified 802.11g devices, and the results have been awesome. I’m [...]
Measurement Lab
Google today unwrapped Measurement Lab (M-Lab) which can measure connection speed, run diagnostics and check if your ISP is blocking or throttling things via it’s blog.
In general it’s a good idea, but it’s nothing new. Sites like dslreports.com and SpeedTest.net have been measuring speed and providing diagnostics for years. The BitTorrent test however [...]
Compiling RRDtool 1.3.x On Mac OS X
I’ve recently been trying to upgrade RRDtool to 1.3.x as I’ve previously been using 1.2.x. New in 1.3 is moving to Cairo graphics, which is pretty cool and provides much better anti-aliased text. MMAP IO should also help since I run it on an old box. It’s a worthwhile upgrade.
Network Perils
It’s been a week of networking pain. For the past few weeks Comcast has been using a low DHCP lease time. 30 minutes to be exact. This is typical of when they are doing network upgrades/repairs and is what a normal network administrator does. It’s similar to lowering the TTL for [...]
Google Mail Fail

Nobody Is Using IPv6
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 [...]
