Under IPv4, remains only a 7% of IP addresses to be assigned, which are expected to be depleted by April 2012

We've talked about the ip address in first half of the semeseter, IPv6 summit meeting at 19, May pointed out the essential need for IPv6 and the possible issue afterwards.

Apparently we'll be out of 0-255 IP addresses in approximately 500 days...

Yahoo has made public its proposal to hack the domain name system (DNS) so as to resolve issues with migrating to IPv6 from IPv4. Internet protocol version 4 (IPv4) was the first widely deployed version of IP that supports 32 bit addresses (equating to 4,294,967,296). The issue of exhausting the 32 bit address allocation was identified in the 1990's, prompting the development of IPv6. IPv6 supports 128 bit addresses, obviously offering a more expansive address system. The article claims that a 'significant percentage of internet users have broken IPv6 connectivity'. Yahoo thus proposes to switch users to IPv4 connectivity once detection of broken IPv6 connectivity is realised. Yahoo will forward its proposal to the Internet Engineering Task Force, however questions of DNS trust and security will surely be the two topics of debate in testing this proposal.

Collecting web data, who is it helping and who is it hurting. Google Analytics is a prominent free to use service that allows everyone from micro bloggers to corporations to record the statistics for visitors to their sites. Analytics can tell you where visitors are from, what they searched for, and what time they visited. They receive this information from your IP address, and ultimately your visit could potentially be traced directly back to your comptuer. Google has created an add-on to help hid your IP address identity, in a likely effort to protect the company from privacy concerns.

"ICANN / IANA and the global technical community would do well to re-assert the principle that the open allocation model for IP numbers - while imperfect - has been cultivated for sound technical and political reasons"

A group of independent film producers have initiated court actions against over 20,000 Bit Torrent users, through an organisation of their own design, a group of lawyers known as the U.S Copyright Group. This group are demanding users to either defend themselves in court or alternatively, to settle outside of court for downloading particular movie titles. Most accused will settle to avoid the costs of litigation. Actions such as this are worrying as may give rise to a standard in which large numbers of corporates, not only in film but in all types of media, may start bringing forth unrelenting actions against individual users- holding them personally accountable. This is problematic (amongst a variety of reasons) that in the identification process through IP addresses is not 100% accurate, leaving room to wrongly accuse some users.

After the Secretary of State in the US Hillary Clinton's speech on Internet freedom, open source source code repository SourceForge.net blocked access to IP addresses originating in Cuba, Iran, North Korea, Sudan and Syria. Open source software provides important infrastructure to these oppressed and developing nations. I hope the American government can see what a blow this is to the infrastructure and fledgling industries in these countries.
