With the Internet only a few short years away from running out of addresses, Taiwan urgently needs to upgrade to a new technology, the head of the Directorate General of Telecommunications under the Ministry of Transportation and Communications said yesterday.
"We need to upgrade to Internet Protocol version 6 [IPv6], as under the current technology we will run out of Internet addresses within two to three years," DGT Director General, Chien Jen-ter (
He was speaking at the eighth Asia Pacific Regional Internet Conference on Operational Technologies (APRICOT) in Taipei.
Computers use IP addresses to communicate with each other on the Internet.
The Internet began in 1969 as a network of US military computers that could communicate directly with each other over telephone lines. It was later expanded to include universities, businesses and individuals.
The current technology, IP version 4 (IPv4), uses a string of 12 numbers for each IP address, limiting Internet adresses to 1 trillion.
Twenty years ago when IPv4 was introduced, it was estimated that a trillion addresses would be more than enough to connect the world.
But, with the invention of the World Wide Web -- a service within the Internet that allows users to access pages of information -- by British scientist Tim Berners-Lee in 1991, IP addresses were required not only for each individual computer, but also for each new Web site.
Six million new addresses are used up across the world each day, Chien said. Upgrading to IPv6 is the solution for expanding shortage.
"IPv6 will dramatically increase the number of available addresses," said Dan Weber, IT manager for logistics specialists the Rehfeldt Group in Taipei.
An Internet engineer agreed with Chien's assessment, but warned of problems during the transition period.
"There is a shortage of IP addresses and time is running out," said Yang Shih-ching (
Tammy Turner, a partner at Pristine Communications, said that there's still a big pool of numbers.
"So many addresses went down after the dotcom bubble," Turner said.
Companies and Internet service providers will need to make the software upgrade, affecting a large number of local users.
At the end of last year the number of Internet users in Taiwan topped 8.5 million, according to the government-funded Market Intelligence Center. That means 38 percent of the population is online, with over 2 million using broadband services alone.
This year the world will pass the 700-million-Internet-user mark, International Data Corp reported.
ISSUES: Gogoro has been struggling with ballooning losses and was recently embroiled in alleged subsidy fraud, using Chinese-made components instead of locally made parts Gogoro Inc (睿能創意), the nation’s biggest electric scooter maker, yesterday said that its chairman and CEO Horace Luke (陸學森) has resigned amid chronic losses and probes into the company’s alleged involvement in subsidy fraud. The board of directors nominated Reuntex Group (潤泰集團) general counsel Tamon Tseng (曾夢達) as the company’s new chairman, Gogoro said in a statement. Ruentex is Gogoro’s biggest stakeholder. Gogoro Taiwan general manager Henry Chiang (姜家煒) is to serve as acting CEO during the interim period, the statement said. Luke’s departure came as a bombshell yesterday.

CROSS-STRAIT TENSIONS: The US company could switch orders from TSMC to alternative suppliers, but that would lower chip quality, CEO Jensen Huang said Nvidia Corp CEO Jensen Huang (黃仁勳), whose products have become the hottest commodity in the technology world, on Wednesday said that the scramble for a limited amount of supply has frustrated some customers and raised tensions. “The demand on it is so great, and everyone wants to be first and everyone wants to be most,” he told the audience at a Goldman Sachs Group Inc technology conference in San Francisco. “We probably have more emotional customers today. Deservedly so. It’s tense. We’re trying to do the best we can.” Huang’s company is experiencing strong demand for its latest generation of chips, called
China has claimed a breakthrough in developing homegrown chipmaking equipment, an important step in overcoming US sanctions designed to thwart Beijing’s semiconductor goals. State-linked organizations are advised to use a new laser-based immersion lithography machine with a resolution of 65 nanometers or better, the Chinese Ministry of Industry and Information Technology (MIIT) said in an announcement this month. Although the note does not specify the supplier, the spec marks a significant step up from the previous most advanced indigenous equipment — developed by Shanghai Micro Electronics Equipment Group Co (SMEE, 上海微電子) — which stood at about 90 nanometers. MIIT’s claimed advances last
GLOBAL ECONOMY: Policymakers have a choice of a small 25 basis-point cut or a bold cut of 50 basis points, which would help the labor market, but might reignite inflation The US Federal Reserve is gearing up to announce its first interest rate cut in more than four years on Wednesday, with policymakers expected to debate how big a move to make less than two months before the US presidential election. Senior officials at the US central bank including Fed Chairman Jerome Powell have in recent weeks indicated that a rate cut is coming this month, as inflation eases toward the bank’s long-term target of two percent, and the labor market continues to cool. The Fed, which has a dual mandate from the US Congress to act independently to ensure
