Google is building a huge computer with a custom operating system that everyone on earth can have an account on. His last few paragraphs are so much more perceptive than anything that's been written about Google by anyone; Skrenta nails the company exactly:

Google is a company that has built a single very large, custom computer. It's running their own cluster operating system. They make their big computer even bigger and faster each month, while lowering the cost of CPU cycles. It's looking more like a general purpose platform than a cluster optimized for a single application.

While competitors are targeting the individual applications Google has deployed, Google is building a massive, general purpose computing platform for web-scale programming.

This computer is running the world's top search engine, a social networking service, a shopping price comparison engine, a new email service, and a local search/yellow pages engine. What will they do next with the world's biggest computer and most advanced operating system?

According to the IPv6 Forum website, the IPv4 Exhaustion Counter’s http://inetcore.com/project/ipv4ec/index_en.html present status is:
Reserved Blocks (IANA) 11% = 30/256 blocks
Until X-day estimation: 736 days
The new solution over IPv4 is IPv6, a new protocol promising to offer the possibility of more unique Internet addresses. IPv6 has been available for sometime now and allows for virtually almost unlimited address space. The adoption of IPv6 has been very slow todate and for the Internet to connect billions of people as well as smart environments comprised of devices that need to run on the Internet to provide new communications services are all need of the addressing space that IPv6 provides.
As earlier mentioned, smart environments use new kinds of applications, like sensor networks, intelligent agents and communication devices. Such an example may be quoted from the construction industry where they are using IPv6 to create smart and intelligent buildings. IPv6 is used to enable Internet based remote controlled security cameras or manage home appliances from remote locations. These smart buildings also save on energy which is a very critical global concern nowadays.
In terms of the state of adoption of IPv6, we stand at the bare minimum. Despite the fact that Telecommunication and Internet Service Provider companies have adequate knowledge about IPv6, the general population that uses the Internet is yet unaware of the issues of IPv4 address space depletion and IPv6 address space counter solutions. There is an expert group of networking engineers and professionals that have been sandbox testing IPv6 in Pakistan but how will this knowledge be passed on to the general Internet user population remains an issue of concern.
Enabling the IPv6 address block is very necessary at this point in time to enable sustainable growth in the use of the Internet but making the switch from IPv4 to IPv6 remains a difficult and daunting task as it takes both time and resources as well as a commitment by all stakeholders including the Government, Private Sector, Academia and Civil Society. Let’s see what the Internetworking experts have to share on this?
