From my IPV4 database, here are the the Registrar and Country statistics as of April 10 2009.
Since the last update, ARIN has crossed the 1.6B IPV4 address boundary, adding nearly 5M IPV4 Addresses. APNIC matched this growth by adding an additional 5M new addresses of its own.
Registrar Number of IPV4 [...]

On a daily basis, I update the Geographic IP database that I created many years ago. Although not as powerful as some of the commercially available Geographic databases, it has more than served my purposes over the years.
One of the benefits of collecting this data is being able to extract substantial metrics on the distribution [...]

The five top-level IP Registrars (ARIN, RIPE, APNIC, LACNIC, AFRINIC) manage tens of million IPV4 and IPV6 addresses, assigning them to networks around the world. These addresses are key to accessing the Internet for all end-users.
About once a year, I generate the statistics out of the IP address database I maintain. The last one was [...]

Through 2007, the number of posts I made per day/week/month decreased steadily. I know post new items 2-3 items a month, or less. After 2 years of steady entries, I just didn’t have anything to add to the conversation.
Having been an A-list groupie for this entire period, I lost touch with the self-perpetuating scene. A [...]

mon.itor.us, a service which also provides free Web performance measurement services, appears to be having a wee problem.

The most recent GrabPERF data on this site is available here. The issue may be corrected by the time you look at the data.
I don’t wish suffering like this on anyone. GrabPERF had it’s own 3-4 day outage [...]

Ugh.

My system has a daily job to collect and aggregate the IP Blocks distributed by the five registrars into a single database, and then provide high-level WHOIS information for this data. If you want to try this yourself, the interface here.
On an extremely irregular basis, I aggregate the statistics from this data, and present it [...]

It has been at least a year since I last updated everyone on the state of GrabPERF. That’s because for most of the last year, the system has been rolling along without a hitch or a major systemic change. The last major change to the agent code was alomost exactly a year ago, when I [...]

Last night, I got motivated.
Ok, I got manic. Goes with my life.
As a part of that mania, I had a breakthrough on how to present GrabPERF data that I’ve actually been collecting for nearly a year: text match failures.
GrabPERF has the ability to match text on page results using a standard PERL regex. By putting [...]

As many readers know, I am going through the process — if you call filing a bunch of paperwork and not hearing anything for 2 years a process — of obtaining Permanent Residency in the United States, often referred to as the Green Card.
This morning, on NPR, there was a story about a foul-up in [...]
