The Internet is to big for its britches.....

[J. Hill]

The Internet as we know it is now officially too big for its britches.

The organization that assigns IP addresses in North America — the numbers that identify every computer, smartphone and device connected to the Internet — ran out of numbers overnight Wednesday. It's not the end of the world, because there's a newer, more robust system rolling out, but it's a milestone in our shared online history, nonetheless.

IP addresses are the four-number strings like 74.125.224.72 that you'll sometimes see in your browser's address bar, in the guts of your smartphone's system settings, or that you might be asked to type in to your cable modem or WiFi router. That address, 74.125.224.72, is one of many that should take you to Google.com.

It's like the highway system. If you're driving through New York, you might take Interstate 95 or I-190 or I-287. But in plain English, it's all the New York State Thruway.

There are five huge nonprofit regional organizations that hand out those addresses around the world. For the first time, the American Registry for Internet Numbers, in charge of North America, had to turn down a request for a block of addresses Wednesday because it didn't have enough.

So it activated its "Unmet Request Policy," it said — basically saying sorry, but if you want all of those requested addresses, you'll have to sit on ARIN's waiting list until they somehow become free or buy them on the open market.

The problem is there are only those four numbers in addresses, which is why the system is called IPv4. It's been in place for more than 30 years, "and even the architects of the Internet could not have predicted the amazing success and universal adoption of the Internet and World Wide Web," said John Curran, president and chief executive of the registry.

"Even optimistically, the total amount of unused or under-used IPv4 address space that could be made available only represents a 'stop gap' measure in the life of the IPv4 Internet," the nonprofit Asia Pacific Network Information Center reported Thursday. "The demand for Internet addresses will only continue to grow."

But the people who run the web have known this was coming for years. In fact, the master organization that doles out addresses for ARIN and the four other regional registries announced more than a year ago that its well was dry.

So work has been under way for years on what's called IPv6 — longer addresses that also include letters. There are only about 4.3 billion possible IPv4 addresses, which engineers assumed would be more than enough in the 1990s. With IPv6, there are about 340 trillion trillion trillion combinations — specifically:

340,282,366,920,938,463,463,374,607,431,768,211,456. (Let's just say 340 gajillion.)

Ideally, you shouldn't see any impact from the switchover to IPv6, since both systems are meant to work side by side. But adoption by Internet service providers and large public organizations has been slow. Google, which monitors whether you get to it through IPv4 or IPv6, says only 21 percent of its U.S. traffic comes through IPv6 — and that's the highest rate of any country in the world.

"It is time for Internet service providers to move to IPv6 to enable the Internet's continued growth," Curran said. "Businesses should be aware that this transition is already well underway for many service providers in the region and make sure that their public-facing websites are reachable via IPv6."

Otherwise, the Internet will remain frozen where it is today.

Where are u getting this information from?

[J. Hill]

news article from my internet home page.

Switching from IPv4 to IPv6 is inevitable, though I question whether we are actually getting close to the 4.3 billion cap that is IPv4. We've been hearing about "the end of IPv4" for years now.

Note this is 4.3 billion public addresses. Public IP addresses do not identify computers, they identify networks (The outside port of a "gateway" router for a network, to be precise). These networks can range from 1 to hundreds of computers, each sharing this public IP address to access the internet.

With the introduction of public/private addressing, classing, and subnets we aren't using anywhere close to 1 public IP address per system. A single address could encompass hundreds or thousands of systems.

According to the article, they are.

According to the article, they are.

The article is a scare tactic. Even in my network engineer class's for college the instructor laughed at the end of ipv4. What Holland has said is the most accurate. I wanted to get more info out of it to make sure if you were talking about ipv4 and ipv6 differences.

You guys are exactly right. Add on to this the fact that addresses are usually leased in ranges, and these leases are almost never used at full capacity. For example, I know the university I graduated from has a 16 bit range (65,536 addresses) and doesn't even use 1% of it.

So yeah, we have run out of non-leased addresses, but we are a good ways from actually using them all.

As has been said, this "problem" has been known about for years, all the backbone of the internet has been capable of using IPv6 for quite a while now, along with routers etc supplied by ISPs so most people should never notice the change. Also yes, a lot of IPv4 address are currently allocated but not used, for example the UK government is selling millions of them (why they thought they would need 16 million who knows!), for quite a profit, so yes IPv4 addresses may not run out, but they may get quite expensive as large bodies that currently have them realise they can make a sizeable profit selling them...

Whoever thought that a Government would profit from Capitalism?
