Famatech's Advanced IP Scanner is a free tool that scans your LAN or Wi-Fi network and provides information about the computers connected to it. Advanced IP Scanner is designed to work closely with the developer's Radmin remote administration software, which adds capabilities. But this simple utility is capable enough to use as a standalone network scanner and robust enough for net admins and other advanced users. It does more than scan and identify the Windows PCs on your network. For example, it can shut down networked computers remotely, and also wake them, if their network cards support the … Read more

What a week for Panasonic. Of all the products CNET reviewed this week, the company scored the best ratings for both the most expensive gadget and the cheapest. There must be some sort of award for that. (Actually, there isn't, but there should be.)

The Panasonic TC-P65VT50 (affectionately known around these parts as the "VT50") is a 65-inch plasma TV that nabbed the hardest-won praise of all: A glowing review from our own David Katzmaier. Katzmaier gets right to the point in his review, explaining that the whole line of TVs in the VT50's series have &… Read more

"Predicting is hard, especially about the future," quips Vint Cerf -- and he should know.

That's because about 30 years ago, when the now-famous engineer was helping to design the technology that powers the Internet, Cerf decided just how many devices could connect to the network. His answer -- 2 to the 32nd power, or 4.3 billion -- looked awfully big at the time. A few decades later, we now know it's far short.

Accordingly, Google's chief Internet evangelist and one of the few people at the company who looks natural in a suit … Read more

Has a slow Web been getting you down lately?

Just imagine if your multibillion-dollar business depended on it, as Google's does. Then imagine the glee in Google's corridors at a significant new victory in the company's attempt to build a Web-accelerating technology it calls SPDY into the Internet.

Earlier today, Mark Nottingham, chairman of the HTTPbis Working Group, announced support for SPDY in an overhaul of one of the networking foundations of the World Wide Web. That foundation is HTTP, the Hypertext Transfer Protocol, and Google hopes SPDY will open up some of its bottlenecks.

The HTTPbis … Read more

LAS VEGAS--In the past, Panasonic's GT variants have been almost as good as the flagships they supported, and at much more affordable prices. We anticipate that this trend will continue with the new GT50.

The GT50 will come in four sizes from 50 inches to 65 inches and ships with an "Infinite Black Pro" panel. The full-HD 3D panel features 2D-to-3D conversion and a new louver filter designed to provide better contrast in lit environments.

With the exception of the Z1, design wasn't a key consideration for Panasonic plasmas until last year, with the "metallic … Read more

Last year, it was neck-and-neck between Panasonic's VT30 and Samsung's D8000/7000 as to the best television of the year...at least until those upstarts from Sharp spoiled plasma's party.

Currently the VT30 still stands as the best TV Panasonic has ever produced, and even if there's only a tiny improvement, the new TC-PVT50 series looks ready to take on that title.

The flagship VT50 will come in two screen sizes, the 55-inch TC-P55VT50, and the 65-inch TC-P65VT50 and features all of Panasonic's current know-how with an Infinite Black Ultra Panel and new louver filter. … Read more

In 2011, Panasonic's ST30 was our favorite TV priced at less than $1,000 and perhaps the best value of any TV we've ever reviewed, demonstrating top-of-its-class performance for the money.

But all good things must come to an end, and the ST30 is moving aside for the ST50.

The ST50 sits in the middle of Panasonic's 2012 range with four sizes starting at 50 inches and includes most of the goodies found in the more-expensive GT50 and VT50 televisions. It's the least-expensive to boast the "Infinite Black Pro" panel, which, if last year … Read more

As the Internet developed there was debate over the network communications protocol to use, but ultimately the fourth revision of IP (IPv4) was implemented for communication between computers and networks. When the Internet was small the 32-bit addressing of IPv4 that limits it to just over 4 billion addresses was perfectly adequate, but recently the last sets of IPv4 addresses have been issued, meaning the size of the IPv4 Internet has reached its maximum.

To overcome this limitation, the Internet Engineering Task Force has been developing a 128-bit addressing system called IPv6 that allows for trillions upon trillions of additional … Read more

NXP Semiconductors has developed chipsets for CFL and LED light bulbs that allow the devices to be operated remotely via wireless networks and portable devices, the Dutch chipmaker announced this week.

The GreenChip iCFL chipset for CFLs and GreenChip iSSL chipset for LEDs have been adopted by lighting manufacturer TCP.

The bulbs can be turned on, turned off, or dimmed.

Both chips operate at the IEEE 802.15.4 standard, the low-rate wireless personal area network (LR-WPAN) standard for many wireless networks, including ZigBee, used to support home smart meters, smart appliances, and security systems.

But the bulb chipset has … Read more
