From long we have anticipated that internet would soon would run of internet addresses, well its gonna happen now. on 19Feb, Internet will run out of global address pool of internet addresses. Lucky though that the "Exhaustion Rate" is just the ranges people like arin/ripe/apnic etc have left to allocate to providers.

ISP's still will have some left to keep going for a bit but there isn't much any time left.

But still, the adoption of IPv6 is not done. our ISPs(Airtel,BSNL etc) do not support IPv6. most websites which I visit do not support IPv6 either. even the software application are not IPv6 ready. so everyone should forget smooth transition from IPv4 to IPv6. its gonna get messy:P

Check out the IPV4 Exhaustion Rate counter at the right of the page below:

APNIC - IPv6 Program

Please clarify this noob, whats the difference between IPv4 address and Internet address?

Both are the same thing. The issue we are discussing here is is a IPv4 addresses coming to an end. Each network device communicating over internet(Public) has a public unique IP address it is a 32bit address (4 Bytes separated by a "."). e.g. 10.12.13.14

Considering its just a 32 bit value and growing number of inter "devices" (Routers/web servers for simplicity) growing by the day, we are running short of these addresses.

There is a new addressing scheme called IPv6 which would eliminate this scarcity, however the devices that are older were ni=ot designed to be IPv6 ready. This includes plenty of undersea routers and some installed in remote irreplaceable places. Upgrading the overall infrastructure (Owned by whoever and wherever) all over the world is highly impossible but inevitable as well.

Do not confuse this with the IP address that your ISP assigns you. The IP is a NATed (Network Address Translated) IP generated for your particular subnetwork.

Anyone has news when our ISP are deploying IPv6? I know about sify which is only IPv6 enabled ISP, AFAIK. Any news about others?

I hope they don't opt for deploying ISP-wide NAT, instead of switching to IPv6. something we have seen that Russian ISP have done. As it would mean everybody gets private IP and stuff like torrenting,rapidshare will be hard to do.

Correctly said, that's why IPv4 would still be in operation for decades to come & there is no known switch off date. I am guessing, networks would probably implement dual stack which means supporting both(IPv4+IPv6).

Man, I hate this. It would make networking more complex:|

They are not exhausting so fast , the data reported on several sites is not complete..

Well, its maybe two years at most but the point is, even that's not enough because its not enough time to replace all the customer side network equipment like routers,usb doungles which are not IPv6 compatible, ISP side devices like routers,load balances,bonding devices which costs million of dollors, Plus all the software(Windows prior to Vista do not support, that include Win98,2000 & XP) & protocols that do not have IPv6 support needs patching.

So get ready for a messy changeover!
 
this is all because of DC's keeps IP addresses reserved... Some people provide IP Address for 2$ , it should have been made expensive well before so that this situation dont arise. many dcs provide 20-50 IP address per server buy for a nominal fee and many IP addresses unfortunately are banned now due to spamm reasons etc.

We really need virtually infinite IP address someday.
 
Update

Approximately 10 days until IPcalypse. 44,544,901 allocatable IPv4s left

The Internet is Running Out of Space...Kind of

No, not really. I think its due to two reasons:

1) It was the burst of devices that need to internet connection, right from your mobile phone,printer,cars,tv to all the way to robots. All need an IP address. further due to virtualization & multiple operating systems on same hardware - they all need an IP address. In 1980s-90s, when internet was composed few hundred nodes all connected with dial up connections, people thought 4 billion addresses should be enough.

2) Inefficient block sizes: IP address are always distributed in blocked. the mistake that was made was block size were either too large for example class A address blocks with over 16 million IPv4 addresses each and next available was a class B block with 65536 addresses which is too small for their intended deployments. IBM, DEC, Apple, HP, MIT all hold that huge Class A blocks and not much is being used.

And IPv6 should solve this problem as it has 128bit addressing which is good for centuries to come

The day has come, its IPcalypse! Please notedown date 2,Feb 2011(early than estimated). It would go down in history of internet as the day when global address pool will be exhausted.



While there is no immediate cause of concern because regional registries will continue assigning addresses but the entire address space is expected to be more or less exhausted by Sept. 24, according to the IPv4 Address Report .

if you an internet junkie, this is kind of historical event;)
 
Now the Final 5 blocks of IPv4 address would be given out to all 5internet registries in a ceremony in Miami.

Further there would be "World IPv6 Day" in June.Web giants Facebook, Yahoo, and Google, with a combined one billion visitors per day, are participating by enabling IPv6 for their main services that day. Content distributors Limelight and Akamai are also joining the party by enabling their customers to participate

so that means all the addresses wil have to be IPv6?

No, IPv4 won't be turned off. It would be a dual stack with IPv4 & IPv6 working in tandem. However, as this is a big switch which has not happened earlier, so there would people who will lose connectivity due to this.

we must not forget india's largest broadband provider BSNL has zero compatibility with ipv6 protocol. #FAIL
 
The Internet as at first designed is about to run out of IP addresses. Our 20-year-old Internet is finally running out of IP addresses The five remaining packets of IP addresses were handed out by the International Numbers Authority Thursday. The INAT is a non-profit organization that has been drawing on the 4.3 billion IP addresses accessible for distribution. A different Web protocol that dwarfs the present configuration will be drawn upon when the original supply of IP addresses is used up.
