Web will run out of IP addresses by 2010

The "father" of the internet has warned that the web will run out of IP addresses by 2010, saying the web does not have enough unique codes that allow computers to communicate with each other.

Vint Cerf, the "father" of the web, said when the internet protocol (IP) addresses do run out, the connectivity of the internet will be damaged and many computers will be unable to go online. "This is like the internet running out of telephone numbers and with no new numbers, you can’t have more subscribers," Cerf was quoted as saying by the Daily Telegraph newspaper today.

The computer scientists, who helped invent the system, called for early preparations to switch addresses to a new system. He underlined that the web does not have enough unique codes that allow system to communicate with each other.

When the internet was developed in 1977 there were 4.2 billion addresses available under the internet protocol version four (IPv4) system.  According to the report in the British daily, each of the IPv4 addresses has a series of 32 binary numbers, but with the surge of broadband globally, it is estimated that these addresses will run out by 2010.

A new system called IPv6 has been ready for a decade and is already used in Japan to connect thousands of earthquake sensors through a computer system that sends automatic alerts to television programmes and turns traffic lights red, the report said.

IPv6 addresses are 128 bits long and so provide a possible 340 trillion, trillion, trillion address space, it said.

Learning Windows Vista : Part 5

Internet Explorer 7.0 Catches Up

IE 7 won’t win any awards for innovation, having not quite caught up with features its
free competitor, the Mozilla Firefox browser, came out with two years ago.
But the improved security of IE 7, plus the addition of long-requested features such as
tabbed browser windows, make Microsoft’s new browser a solid component of the OS
rather than the backward stepchild that IE 6 became. (Users of Windows XP can and
should download and install IE 7, if an upgrade to Vista isn’t immediately possible.)
Besides the tabbed windows, IE 7 has (thankfully) copied several other features from
Firefox, Opera, and other non-Microsoft browsers. These include the ability to add
Internet search engines of your choice to IE’s search bar and a default Shink to Fit setting
so Web pages will fit your printer’s paper size.

However, IE 7 has also gained a few new features that other browsers may themselves
need to catch up with.

Pressing Ctrl+Q or clicking the Quick Tabs tab on the IE 7 toolbar tiles all of your
open tabs into a convenient thumbnail view (see Figure 9). When you have a lot
of tabs open, Quick Tabs can save you a substantial amount of time that you
might otherwise spend clicking at random to get back to a particular site

Page Zoom is another handy feature. When you’re viewing a web page that’s
just too small or too large, hold down the Ctrl key and press + to make the page
10 percent larger, – to make it 10 percent smaller, or 0 (zero) to return the page
to its original size.

These special keystroke sequences work exactly the same way as they do in
Firefox, except that IE 7 scales both images and text. (Firefox 1.5 scaled just
text.) The keystrokes work whether you use the symbol keys on the main keyboard
or the numeric keypad.

There’s also a small Page Zoom button on the extreme right of IE 7’s status bar.
You can click it once to scale a Web page to 125 percent, click it again for 150
percent, and click it a third time to go back to 100 percent.

Quick Tabs. Press Ctrl+Q in IE 7 and all of your tabbed windows are tiled, showing
you a thumbnail to help you switch to a desired Web page

SECRET:

Fit the Full URL on Printouts
Sometimes, you want to print out some Web page you’ve found, so you can recommend
the site to a friend later. But if the Web address (URL) is a long one, it’s
likely to be truncated in the footer of the printed page. That’s because IE, by default,
uses a large font and cuts off any of the URL that doesn’t fit on the same line as
today’s date

You can make URLs print in full almost every time by clicking Tools?Internet Options.
On the General tab, click the Fonts button and then select a Web page font that’s
more compact than Times New Roman, such as Vista’s Cordia New. (This font, which
is similar to Arial, also becomes the default font for Web pages that don’t specify a
font.)
If that doesn’t print the entire Web address, give URLs a separate line. To do so, pull
down the Printer toolbar and select Page Setup. Enter &b&u in the Header field to
devote the full header to the URL (aligned to the right). Then enter &d&b&p in the
Footer field to print the date on the left and the page number on the right at the bottom
of each page. (This procedure eliminates printing each page’s title, represented
by &w. A Web page’s title takes up space that’s best devoted to printing the full URL,
in our view.)

Instant Search and the Search Pane

An interactive Instant Search bar is now a feature of every Explorer window in Vista as
well as Vista’s Start menu. This may not slow the progress of third-party desktop search
applications that are increasingly being promoted as Windows downloads from the major
search engines. But Microsoft is, in fact, trying to build into Vista advanced search functions
to render such downloads unnecessary. Figure 6 shows the results of .jpg entered in the search bar of the Start menu. Pressing Enter opens the more-capable Search pane. In this pane, you can refine your search or organize the results by file size and other attributes.

shown, which looks quite busy

Selecting just options applets. By entering the word options into the Control Panel’s
search bar, only those applets with that word in their titles are displayed, making your choice easier.

Programs Explorer Replaces Add/Remove Programs

Legions of Windows users have become accustomed to using the Add or Remove
Programs dialog box in the Control Panel to uninstall applications that they no longer
want taking up space on their hard disks. So, in its frustrating way, Microsoft has renamed
this feature to make it even harder to find than it was before. To reconfigure or completely remove an application, you now use the Programs Explorer (see Figure 4). This applet also enables you to turn on or off many of the built-in features that come with Windows Vista, such as the Indexing Service. Fortunately, the Programs Explorer is still available through the Control Panel. You just
need to know to look for it in the Ps instead of the As.

Put Some Gadgets in Your Windows Sidebar

Apple users have long been able to take advantage of the Mac OS X Dashboard, and
Windows users have been able to download Yahoo Widgets (formerly Konfabulator
Widgets). Those things are still available, but now Vista has its own little tools, known as
gadgets.
Vista gadgets live in the new Windows Sidebar (see Figure 5)—which you can move to
the left or right side of the screen by right-clicking it and selecting Properties. Or you can
put Gadgets on your Desktop by dragging the little context menu that appears when you
hover your mouse over a Gadget.
Using the Properties dialog box, you can configure the Windows Sidebar to start every
time Windows starts or only when you want it to appear. If you configure it to require
manual intervention, get it back by clicking Start?All Programs?Accessories?Windows
Sidebar.
