IPv4 addresses will end at the beginning of 2011

The number of free IPv4 addresses has been reduced to 5%, according to The Number Resource Organization (NRO). The supply of free addresses began to strain, when in January of this year their number dropped to 10% . Over the next nine months, IANA transferred around two hundred million addresses to regional Internet registrars.

NRO suggests that the last block of addresses will go away within a few months. This topic has been discussed for a long time. In fact, concern about the depletion of the stock of IP addresses of the fourth version did not appear yesterday, but at the end of the distant eighties, when the Internet showed signs of future avalanche growth.

Axel Pawlik (Axel Pawlik), the head of NRO, argues that this situation can not but worry, and the only acceptable way out of this situation is a timely (in the light of recent news with self-sustainability somehow failed) transition to  IPv6 .

IPv6 has a significantly larger address space than IPv4. This is due to the use of 128-bit addresses, while IPv4 uses only 32 bits.

NRO expects that in  2010 , the five registrars will allocate more than 2,000 IPv6 blocks, which is 70% more than in  2009 .

The Number Resource Organization subtly hints that without proper preparation and sensible steps to implement IPv6, a chaotic fight for addresses will begin, which will negatively affect the stability and security of the global network, thereby causing a wave of unpleasant expenses.
