IPv4 Addresses Are Coming To An End

By on February 8, 2011

An important news  happened in the World Wide Web. Non-profit organization IANA (Internet Assigned Numbers Authority) managing IP address space, top-level domains, as well as recording the data types and MIME parameters other Internet protocols, distributed two of the seven remaining blocks of network addresses using the Internet protocol there is a fourth version (IPv4) .
Recall that the IPv4 is a 32-bit protocol, the maximum number of Internet addresses in it is 4,300,000,000 (2 to 32-degree). Once this number seemed unattainable, but now, when connected to the Internet is increasingly a wide variety of gadgets and an army of web users is also growing by leaps and bounds, there is the problem now that is acute shortage of IP-addresses.

Thus, in stock at the online community is just five free blocks of IPv4 addresses, one for each five Regional Internet Registrars (RIR) which are expected to be automatically distributed in the near future. Subsequently, these addresses should be distributed among the truly needy in their Internet service providers and other companies.

Probably, the remaining five blocks of IPv4 addresses will be distributed at the current week. Thus becoming increasingly relevant passage in the sixth version of Internet Protocol (IPv6), is able to provide the number of addresses equal to 2 at 128 degrees (the number of IPv4 addresses, we recall, is 2 to 32 degrees, that is 4,3 billion). However, to implement this transition to 128-bit IP protocol will require much effort on the part of Internet service providers, device manufacturers and software developers, as well as the leading network of resources and consumers.

The transition to a new protocol, however, hampered by a lack of equipment for site owners to display the content under the new addresses, as well as lack of user devices that recognize the new addresses.
Old and new protocols are not compatible. All devices that are currently working on the IPv4, should be transferred to the new protocol. Producers will have to reprogram a huge number of different techniques, and users – to change not only software but also the hardware necessary to access the network.

While the issue is not resolved, providers will assign multiple users to one common address, making it impossible for the popular services such as, for example, Google Mail,  and Google Maps.

The news is based on the report published by the famous tech blog CNET .
