ONE technique, called DUAL stack, involves running IPv4 and IPv6 at the same time. End NODES and routers/switches run both protocols, and if IPv6 communication is possible that is the preferred protocol. A common dual-stack migration strategy is to make the transition from the CORE to the edge.

The Internet Protocol version 4 (IPv4) is a protocol for use on packet-switched Link Layer networks (e.g. Ethernet). IPv4 PROVIDES an addressing capability of approximately 4.3 BILLION ADDRESSES. The Internet Protocol version 6 (IPv6) is more advanced and has BETTER features COMPARED to IPv4.

Possibly never. The purpose of deploying IPv6 is to ensure network growth and continued interconnectivity when IPv4 address space becomes depleted and DIFFICULT to obtain. In addition, as the global Internet continues to expand, it is likely that some Internet sites will only be available via IPv6.

To avoid problems, one should be fully IPv6-enabled by the time IPv6-only sites START appearing. However, in practice, it is only the public (or user) facing part of an enterprise's infrastructure that needs to be IPv6 enabled at the outset. The back-end infrastructure - which users do not interact with directly - can continue to be BASED entirely on IPv4, so long as that is the most cost-effective approach. (Enterprises may determine that it is more cost-effective to PROGRESSIVELY turn off IPv4 in PARTS of their network once it is no longer needed or in significant use.)

One should expect, however, that it might never be cost-effective (or possible) to upgrade certain legacy systems. Thus, it will likely be a decade or more before enterprise sites find themselves in a position to consider completely turning off IPv4. In practice, there is no need to turn it off so long as IPv4-only applications still remain in use.

You will need to obtain new IPv6 addresses in addition to your existing IPv4 address BLOCKS. IPv4 address space that you have TODAY can still be used in a dual IPv4-IPv6 environment. The RIRs all have policies that make it straightforward for an ISP with IPv4 space to apply for and receive IPv6 address space. You should contact the RIR for your region or your ISP for more information on how to acquire IPv6 addresses.

It may also be good idea to use this opportunity to redesign your addressing plan, taking advantage of the greater flexibility of IPv6 to assign subscriber address blocks more optimally. Similarly, customer SITES may use IPv6 as an opportunity to redesign and optimise their internal addressing plan. However, it may be possible to re-use an existing subnet addressing plan WITHIN the new IPv6 block, if that is preferred.

No one will put a date on when IPv4 will be TURNED off. This will depend on market forces. When IPv6 becomes the dominant NETWORK it will DRAW more people in and less people will worry about IPv4. There will always be backwards COMPATIBILITY for THINGS like older network printers that cannot transition to IPv6.

No. Both IPV4 and IPV6 will RUN in parallel until there is no longer any need to do so.

No. Both IPv4 and IPv6 will run in parallel until there is no longer any need to do so.

IPv4 addresses and IPv6 addresses are not automatically COMPATIBLE with each other, so network operators need to make investments to ensure that this can happen. Some network operators are not prioritizing the investment to make their SOFTWARE and hardware IPv6-ready.

The RIRs and other industry partners are WORKING hard to ensure that everyone is aware of IPv4 depletion and the importance of preparing for the widespread adoption of IPv6 on the INTERNET.

Internet users won’t notice the effect of IPV4 depletion in the FORESEEABLE future.

However, in the future there may be parts of the Internet that you cannot reach if the website or service is an IPV6-only NETWORK and your Internet Service Provider (ISP) does not provide its customers with IPv6 addresses.

As long as the RIRs still have available IPv4 address space, they will CONTINUE to DISTRIBUTE it in ACCORDANCE with their regional policies.
We cannot PREDICT how long each RIR’s POOL of IPv4 address space will last.

IPV4 ALLOWS for a maximum of just over four BILLION unique addresses (for example: 10.142.131.235). It is LIMITED by the NUMBER of unique number combinations that can be created in this format.

YES. The INTERNET will CONTINUE to work and the IPv4 ADDRESSES ALREADY in use will continue to function.

Yes. The Internet will continue to work and the IPv4 addresses already in use will continue to function.

It means that the central POOL of AVAILABLE IPv4 addresses MANAGED by the IANA is empty. As of February 2011, most of the FOUR billion IPv4 addresses available have been allocated for use or reserved for a specific technical purpose.

Yes. Most of the operative systems that currently support IPV6 ALLOW the SIMULTANEOUS use of both protocols. This way, the communication with IPv4 only networks as well as IPv6 only networks is possible, and the use of the APPLICATIONS designed for both protocols.

Yes. Most of the operative systems that currently support IPv6 allow the simultaneous use of both protocols. This way, the communication with IPv4 only networks as well as IPv6 only networks is possible, and the use of the applications designed for both protocols.

IPv6 is not backward COMPATIBLE with IPV4. These two protocols cannot TALK to each other DIRECTLY.

The biggest limitation of IPv4 is its 32-bit addressing space resulting in about 4.3 billion IP ADDRESSES only. The rapid growth of internet, WIRELESS subscribers and deployment of NGN technology is leading to accelerated consumption of IP addresses with the RESULT that IPv4 addresses are almost exhausted TODAY.

IPv4 uses 32 BITS to address COMPUTERS on the Internet. That means it can support 2^32 IP addresses in total -- around 4.29 billion. In the 1980’s a 4 billion computers on the Internet seemed like impossibility. Surprisingly, almost all 4.29 billion IP addresses have now been assigned to various institutions, leading to the crisis we face today. We have not totally run out of these addresses but with the growing POPULATION and the ever INCREASING number of DEVICES that connect to the Internet, the day when we shall completely exhaust these addresses is very near. Hence the need to shift to a system that offers a larger addresses space.

IPV4 stands for INTERNET Protocol version 4. It is the fundamental technology that makes it possible for us to connect our devices to the Internet. WHENEVER a device accesses the Internet it is assigned a unique, numerical IP address such as 128.255.244.221. To SEND data from one computer to another through the Internet, a data packet must be transferred across the NETWORK containing the IP addresses of both the sender and the receiver. Without IP addresses it is not possible for devices to communicate with each other. It is fundamental to the existence of the Internet.
