At the current rate of growth of the internet, when will we run out of IP addresses?

ICANN can't extend the IP numbering since IPv4 protocol which we uses right now as Global Standard consist of 4 bytes (there is 4 bytes of data in every IP address, this data represents what IP are you in). 4 byte number is chosen because computer works with data in bytes, and is best to work IP in bytes numbers too. 1 bytes is equal to 8-bit which is equal to 256 variations, so the whole IP address, currently can hold 256*256*256*256 number of unique address, which is appr. 4.3 billions address. Computers works practically in bytes, and it's hard for computer to work with numbers that is not byte based. \n\nThus it is hard to change the protocl by simply adding the numbers to it.\n\nHowever, there is a new protocol called IPv6 which extendss IP address, and still using bytes based numbers. It is by adding more bytes, thus increasing the number of IP address, while still computationally efficient. \n\nIPv6 works by using 8 groups of four digits hexadecimal (base 16) numbering. Hexadecimal is one of the number bases that is easy to compute by computer. This new protocol support 3.4 x 10^38 number of unique IP address.

great question! hmm.. I guess the easiest thing to do would be to take down the root servers and IANA ICANN servers, which currently are ALL located in the U.S. and under U.S. sovereignty, which really angers the rest of the world. For the next few years ICANN will still be wholly operated domestically, but it remains to be seen what will happen beyond that. At the moment the U.S. technically has the power to "take down" the entire internet due to this topology. \nIt's really not possible to destroy the internet from the outside; most of the infrastructure that would be succeptible to an attack is distributed via anycast, and doesn't have a true physical location. Therefore, redundancy would kick in and nothing would "go down." However, all it would take is a corrupt entity within ICANN or the U.S. dept of Commerce to internally destroy the internet. It wouldn't take long for communications to rebuild themselves though, and in the process, other nations might find ways to permanently avoid dealing with ICANN and our root servers completely. scary!

Well, assuming that there were any available in the class b space (which there isn't), and assuming that you could justify to ARIN that you NEED a full IPV4 Class B (which would be pretty hard), it would cost you $9000 initial fee + $9000 /year allocation fee.\n\nYou might be able to buy the space from someone else -- say Haliburton (who has a class A), but I wouldn't expect to pay less than $1Million if that were the case.\n\nThe real question is why, in this day of network address translation, would anyone really NEED that many addresses?

A lot, though it's hard to measure.\n\nYou can't do it by connections to the server because some people use more than one protocol at a time (I use MSN, Skype, AIM, ICQ and Yahoo).\nYou can't do it by IP connections either, because to the outside world each LAN has only one IP, but may have hundreds of thousands of IM users behind it.

You can't. They are providing it to certain IP addresses only. Sometimes it shows up and sometimes it doesn't. It's getting rather annoying.

Depends on if your provider uses dynamic or static IP's.  You could always use another provider.....

According to the site "waybackmachine.org" an archive of internet pages, it holds 40 billion web pages archived from 1996 to a few months ago.\n\nThe surface web, or the publicly available documents is estimated in 2.5 million documents. The deep web, is 400 to 500 times bigger.\n\nSo the internet (just the web, not counting email, ftp, usenet, etc) is estimated at 550 billion connected web documents.

Given the investment required to provide universal broadband access and the potential for profit in controlling the broadband pipe, it's hard to imagine it will ever disappear completely.  It will likely change though, as in those who have dial-up vs. broadband; or those who have high speed broadband vs. slow broadband; or free wifi vs. fiber-to-the-home.  Look at the evolution of mobile devices and services for clues.

Depends on wha the isp offeres, really. Almost all home users have a dynamic ip, which means they have one ip, but that ip changes from time to time. To have multiple ips you would need to have been assigned multiple static ips, which never never change, and you'll almost always need to pay more to get that service, if the isp offers it at all.

The nature of the routing of the internet,

Absolutely not. The internet is controlled by humans, it doesn't expand on its own. It doesn't have the ability to expand on its own and it never will have the ability to learn anything. It doesn't learn. Thats like filling a pitcher with jello and saying, "Look it's a living being. It has a structure, it holds what i put into it and it wiggles when i touch it!!"

There is no point in banning IP Addresses. Most people have dynamic IPs today anyway. And the people who dont... they can use ARP poisoning to fake their IP Address. Also if an ISP recycles IP Addresses quickly you could be banning someone you dont want banned and, in the long run, losing hits on your site.\n\nEdit: But, what you can do... Have your site reconize cookies and send the person you dont want coming to your site a cookie, so when they go to the site the site will reconize the cookie and block him. But, of course, cookies can be deleted.

It would be helpful if you posted some basics about your internet connection.  56k users will be doomed to such happenings, as sometimes "noise" over the connection will cause packet losses.  Also, peak internet use times will cause those types of problems.

You want to have 40,000 IP addresses on a single PC? Dear God, why?

The internet.  Enormous, has almost literally made the world smaller.

they might sell your IP address to their advertisers and that will lead to junk e-mail and possibly hidden viruses eventually.Then again, that could happen with most websites.

With the combination of NAT and Private address space that can be used repeatedly, An IP address is often used many times. This allows the existing address space to be stretched to a point where running out has not become an issue.
