### Internet officially runs out of IP Addresses

The Number Resource Organization (NRO), an industry group made up of five regional Internet provider registries, announced on Feb 3 that the free pool of available IPv4 addresses is now fully depleted. It had handed out the last of the available addresses on the old system.

The future of the Internet is in IPv6. All Internet stakeholders must now take definitive action to deploy IPv6.

The old system, called IPv4, uses a system of numbers, typically separated by decimals, like 192.0.6.148. IPv4 had about 4 billion addresses (32 bits), which ran out more rapidly after mobile devices with Internet connections became commonplace. Now all new Internet addresses will use IPv6, a system that has more numbers and characters, and is said to have enough spots for 340 trillion, trillion, trillion unique IP addresses (128 bits). The two systems aren't automatically compatible with each other, however, so service providers and network operators need to upgrade systems to ensure the transition is smooth, which is why there has been so much recent attention focused on the subject.

Some facts on IPv6
• Since IPv6 addresses are 128 bits long, the theoretical address space if all addresses were used is 2128 addresses. This number, when expanded out, is 340,282,366,920,938,463,463,374,607,431,768,211,456, which is normally expressed in scientific notation as about 3.4*1038 addresses. That's about 340 trillion, trillion, trillion addresses.

• It's enough addresses for many trillions of addresses to be assigned to every human being on the planet.

• The earth is about 4.5 billion years old. If we had been assigning IPv6 addresses at a rate of 1 billion per second since the earth was formed, we would have by now used up less than one trillionth of the address space.

• The earth's surface area is about 510 trillion square meters. If a typical computer has a footprint of about a tenth of a square meter, we would have to stack computers 10 billion high blanketing the entire surface of the earth to use up that same trillionth of the address space.

Looks like this figure is almost infinite.

### Ho Ching named 5th most powerful and is mistaken as first lady by Forbes

Forbes named Singapore Prime Minister wife and CEO of Temasek Holdings, Ho Ching, as the 5th most powerful woman in the world. Ho Ching is mistaken as Singapore's first lady! OMG!

I wonder how can Forbes makes such a blunder. For a complete list, refer to here.

### How to stop FortiClient from starting automatically?

Installed FortiClient recently but the challenge in disabling the application/service from running automatically on every start-up annoyed me. Attempt to stop 'FortiClient Service Scheduler' only return 'Parameter is incorrect' error message.

An article on Technet help solve my trouble. To stop FortiClient from starting automatically, try the following:
Shut down FortiClient from the system tray.
Run net stop fortishield on command prompt.
Run msconfig.
On msconfig, switch to the Services tab. Clear the FortiClient Service Scheduler check box and click Apply.Run services.msc on command prompt to open up show all available services.Look for FortiClient Service Scheduler. Switch Startup type to Manual.Restart your computer. FortiClient should not be running automatically the next time round. Hope it helps.
QET next week

My friend admitting to NTU this month had had their QET few days back and from them, their QET's format was straightforward and questions to me was simple. 2 close passages with some blanks for students to fill in and a 300 words essay to be written from many topics to choose from. Topics available to choose from are like "Why do you choose NTU?", "Describe one major recent event just happened in your country", "What do you want to do in the future?", etc. Very simple to write essay with 300 words limit. But then for NUS, it is a very different story. 1 close passage with many grammatical phrases underlined for you to edit and a 500 words essay to write. Before writing the essay, there will have 3 pre-reading topics for students to ponder and then a lengthy topic related article to read from. There is only ONE essay TOPIC to write on and it can be like "how your country's goverment can help reserve the originality of tourist spot…
