ICANN announces last IPv4 address blocks distributed
The Internet Corporation for Assigned Names and Numbers (ICANN) announced last week that it had distributed the last blocks of IP addresses in the current system. Most Internet devices today use the IPv4 standard, which is limited to several billion addresses. Regulatory bodies and technology leaders have been pushing IPv6 for several years, and the exhaustion of the IPv4 pool will accelerate this rollout. The IPv6 system allows for an exponentially greater number of addresses.

Facebook adds new account protection feature
Facebook began rolling out a security feature last week that aims to protect users’ accounts. The new feature uses the HTTPS protocol — the same technology that protects many e-commerce sites — to encrypt communications. Users must enable the feature themselves in the Account Security menu under the Account Settings panel. By taking advantage of HTTPS, Facebook users can avoid having their accounts hijacked when using unsecured connections such as those at airports and coffee shops.

Jeopardy champs to face off against IBM computer
Watson, a computer developed by IBM and Carnegie Mellon researchers, will make history as the first nonhuman contestant on Jeopardy on Feb. 14. Like Deep Blue, the IBM computer that defeated Garry Kasparov at chess in 1997, Watson will use a combination of raw processing power and complex algorithms to answer host Alex Trebek’s trivia questions. The computer is designed to understand the subtleties of human speech, and IBM researchers hope that similar technology will one day be available to everyone.
