IP Address shortage to hit Internet soon

That’s true my friend. IP Addresses are soon to go out of stock 🙂
It means that if you want to get an IP Address to go online, you would not be able to do so because all the IP Addresses have been already allocated and none are left.

I’m a newbie. Can I get the basic knowledge about the IP stuff ?

Yes .

But what exactly is IP ?

IP (Internet Protocol) are set of rules designed for transmitting data over the Internet.

Then What is IP Address ?

IP Address is a unique label given to the device(ex. computer) to identify it in a computer network that uses Internet Protocol for communication.

What is the format of an IP Address ?

The designers of the Internet Protocol defined an IP address as a 32-bit number and this system, known as Internet Protocol Version 4 (IPv4), is still in use today.

The format of an IP address is a 32-bit numeric address written as four numbers separated by periods. Each number can be zero to 255.
For example, could be an IP address.

But we don’t enter IP Addresses ? We only use website names.Who keeps this mapping record ?

Generally users do not utilize IP addresses directly, instead using words to access the servers and computers they wish to visit. Inputted domain names are connected to their Internet protocol addresses through the domain name system (DNS), which keeps a record of all domain names and the IP address they are related to.

Who gives these IP Addresses ?

Internet Corporation for Assigned Names and Numbers(ICANN) is a non-profit corporation headquartered in Marina del Rey, California, United States that was created on September 18, 1998  is responsible for managing the Internet Protocol address spaces (IPv4 and IPv6) and assignment of address blocks to regional Internet registries, for maintaining registries of Internet protocol identifiers, and for the management of the top-level domain name space (DNS root zone), which includes the operation of root nameservers.

What is the maximum number of IP address in IPV4 ?
IPv4 uses 32-bit addresses (4 billion, or 4.3Ă—109, addresses).

What is the solution if IPV4 or current IP Addresses used completely ?
IPV6 is the solution.
The number of addresses that IPv6 allows for amounts to 340 “undecillion” (followed by 36 zeroes); enough for a trillion people to each be assigned trillions of IP numbers, according to ICANN chief Rod Beckstrom.IPv6 uses 128-bit addresses (340 undecillion, or 3.4Ă—1038 addresses).

Current Updates :

  • Once the supply of IPv4 addresses ICANN distributes to the five regional centres around the world are gone, computers and other gadgets might have to start sharing instead of having unique identifying numbers.
  • New websites or online services stuck with shared IP addresses wouldn’t perform as well as pre-existing offerings that have numbers all to themselves.The effort and expense of changing to IPv6 would fall mostly on service providers, websites and network operators that have to make sure systems can handle the new online addresses and properly route traffic.
  • Consumers, for the most part, shouldn’t notice the switch since complex IP numbers would still appear to them as words and domains, such as icann.org.
  • Some people might need to update routers or modems that connect computers to the internet.
  • In a worst case scenario, running out of IPv4 addresses with no switch to IPv6 would mean new gadgets wouldn’t be able to connect to the internet because addresses weren’t available, according to ICANN.
  • Beckstrom said that though people might not face heavy problem but if enough networks don’t move to IPV6 then people should soon get offline because iPAD, iPHONE or next generation devices cannot be connected.

A full shift to IPv6 will take years, with the remaining stock of old IP addresses being allocated to support the transition, according to Beckstrom.

    I really hope they speed with this whole IPv6 adoption thing…. It’s urgent.
