In 500 Days, the Internet Will Run Out of IP Addresses!

2010-05-20T16:45:00.002+05:30

Everyone in the world is very much familiar about the Internet. Now aroused a problem of shortage even for the ip address too.

Internet apocalypse seems imminent. In approximately 500 days, it has emerged, IP addresses used to distinguish one computer from another will run out.

The unique numbers, which are known as Internet protocol addresses, help identify the world's networked devices.

An IP address uses four numbers from 0 to 255 to distinguish one computer from another. There are more than four billion combinations. But the proliferation of networked devices means soon that will no longer be enough.

In a way, IP addresses are like phone numbers, which need to be entered correctly if a right connection is to be made. So the ability to uniquely identify everything in the computer world is essential.

IP addresses are like phone numbers in another way, too.

Just as India has to move from ten-digit mobile numbers to eleven digits in the future, massive change will now be required globally to resolve the problem.

However, there's a complication.

"Unlike the telephone system, it's not easy to just add more digits"

But every web server, every iPhone, every router and everything else - possibly billions of devices - will need to be reconfigured or upgraded.

"The idea that every last one has to go back into the doctor for a new transplant does sound a bit frightening. It's almost like having to teach every device a new language"

Fortunately, a new language exists.

Computers now use IP version 4 and have since the 1980s. Its replacement is version 6, known as IPv6. For humans, little will change.

The traditional way we visit a website, by typing google.com or facebook.com, won't be any different and personal computers will automatically use IPv4 or IPv6 as required.

The impending shortage has been apparent for more than a decade as the volume of networked devices has escalated but inertia has stymied efforts to prepare for IPv6.

While personal computers have been capable of understanding IPv6 since Windows XP and Apple OS X, only about 5 percent of devices are configured to do so. Among web servers, the figure is less than 1 per cent.

Internode is one of the few Internet service providers that offers an IPv6 service. Telstra is among the many that do not. Tens of millions of mobile phones are on an IPv4 network only.

In India, there is no talk about IPv6 Implementation at all. In order to implement, it needs large amount of investment for the hardware and software upgradation of the telecom equipments.

Technically, it's not all that difficult to enable IPv6. Logistically, it's a horrendous challenge, and the conversion can involve substantial costs, with little in return.

"It doesn't make your Internet any shinier or any brighter, so we the customers won't like to pay more for that and we won't do it"

At last, we will get to a point where large numbers of people will no longer be able to see everything on the Internet.

So far, the dwindling storehouse of IP addresses has been managed with trickery that translates one IP address to another.

But by about late September next year, the key body that distributes IP addresses will run out of them. Three months after that, every drop in the pipeline will dry up and the only way to get an IPv4 address will be to buy one from someone else.

Lacking that, consumers whose computers are not configured to use IPv6 won't see new websites. Likewise, iPhones, which don't understand IPv6, will be limited to the "old" Internet.

For businesses that are not prepared, this could spell trouble. Unless web servers and mobile phone services are configured to send information via IPv4 as well as IPv6, companies could be left with a fraction of their current customers.

The good news is that once IPv6 is in place, it should satisfy demand as far as a computer can calculate.

"If every single address was one grain of sand, in IPv6 we could build 300 million planets the size of Earth"

BSNL CDMA WLL INTERNET CONNECTION PROCEDURE IN LINUX

2008-08-16T19:11:00.006+05:30

HERE i will give you the procedure for connecting the internet in linux using BSNL CDMA WLL dial-up conection using data cable (usb to usb or usb to serial)

1. Connect your cdma wll phone using data cable and then switch on your phone

2. Set the Always on option for data in the phone

3. Now boot your machine in Linux Operating System

4. Login as root user

5. Open the terminal it looks like command prompt..
to open the terminal it may vary depending upon the various linux operating systems mostly it will be in the system tools

6. Issue the command wvdialconf it will search for the modem devices in your machine

7. If it displays the modem found at ttyUSB0 or some thing like that then there is no problem for you in identifying the modem then skip to step no.12

8. If it displays no Modem found then you have load particular driver modules into the kernel for detecting your modem

9. Type lsusb in the terminal it will display the devices that are connected in the usb ports

10. Look for your phone device there
it displays like below ...

[root@localhost ~]# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 002: ID 15eb:0001
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
[root@localhost ~]#

11. HERE 15eb is the vendor id and 0001 is the product id

Now create the rules file named as /etc/udev/rules.d/50-cdma.rules

procedure for creating a file

In the terminal type vi /etc/udev/rules.d/50-cdma.rules and press Insert key for typing the rules in to it

SUBSYSTEM=="usb",SYSFS{idproduct}=="0001",SYSFS{idVendor}=="15eb",RUN+="/sbin/modprobe usbserial vendor=0x15eb product=0x0001"

SUBSYSTEM=="usb",SYSFS{idproduct}=="0001",SYSFS{idVendor}=="15eb",RUN+="/sbin/modprobe ppp_generic"

now press ESC key and type :wq! and then press enter ro save and quit
reboot the system and give the command wvdialconf now the modem gets detected and gives some thing like this

[root@localhost ~]# wvdialconf
Editing `/etc/wvdial.conf'.

Scanning your serial ports for a modem.

Modem Port Scan<*1>: S0 S1 S2 S3

ttyUSB1<*1>: ATQ0 V1 E1 -- failed with 9600 baud, next try: 9600 baud
ttyUSB1<*1>: ATQ0 V1 E1 -- and failed too at 115200, giving up.

Found a modem on /dev/ttyUSB0.
Modem configuration written to /etc/wvdial.conf.
ttyUSB0: Speed 9600; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"
[root@localhost ~]#

12. Open the file wvdial.conf by giving the command as follows for editing and configuring the connection

vi /etc/wvdial.conf and press Insert key for typing

add the following script in to that file

[Dialer BSNL]
Inherits = Modem0
Init1 = ATZ
Init3 = AT+CRM=1;+CPS=33;+CMUX=1;+CTA=0
#the above line is only for htl phone this is the extra initialization commands according to your #phone you can add your own initialization commands

Stupid Mode = 1
Phone = #777
Area Code = 044
Username =
Password =

[Modem0]
Init3 = ATM0
Init1 = ATZ
SetVolume = 0
Modem = /dev/ttyUSB0
Baud = 460800
FlowControl = CRTSCTS
Dial Command = ATDT

in the above script use your username and password for establishing the connection

now press ESC key and type :wq! and then press enter ro save and quit

13. In the terminal issue the command as wvdial BSNL

now you will be able to get connected to the internet ...

14. To get disconnected from the internet press Ctrl + C

I think this will be very useful for connecting internet in linux through mobile or using cdma wll phone or usb modem like the reliance Netconnect and Tata's Plug and surf connections..

If you have any doubts you can post your comments so that i can clear all your doubts...
