Monday, July 8th, 2013

If you need to know if your favorite website (or even your own website) supports IPv6, here’s a Firefox app that will help you to figure it out …

The Internet is still alive and kicking even though the world has run out of IP addresses. There was some craze about this some time ago but it has somehow died off again.

Wednesday, June 6th, 2012

One thing that will definitely come in handy in the IPv6 world, is an out-of-band management solution that supports IPv6 ….

IPvFox – Display All Connections a Web Page Makes

Friday, September 9th, 2011

Here’s an interesting add-on for Firefox; I don’t think it would make my job any easier, but it would definitely be educational.

Chance is that the web pages that you are connecting to with your web browser load elements from different web servers, and not from one. This is for instance the case if a Facebook Like, Twitter or Google Plus button is displayed on the site. Sometimes though you may want to get an exact list of all connections that are made to display the contents of a web page. This can be handy to make sure that the site does not leak information to third party companies, that a site has not been hacked and that a site does not make connections to known malicious servers.

You may have seen an increasing number of articles about IPv6 in the past year. IPv6 is an Internet Protocol that has been designed as the successor of the currently used IPv4 protocol.

Could the Change to IPv6 Break the Internet?

Friday, November 12th, 2010

Great. Now we have something else to worry about … but it least it makes an interesting topic for a story.

It’s been widely reported that the old IPv4 Internet addressing system is creaking under the weight of the demands placed on it and that the available addresses will run out completely by January 2012.  It’s replacement, IPv6 has now been with us for a while but it’s worldwide roll-out is hardly something that can be called hasty.
