IPv4 addresses will end at the beginning of 2011

The number of free IPv4 addresses has decreased to 5%, as reported by The Number Resource Organization (NRO). The stock of free addresses began to strain when in January of this year their number dropped to 10% . Over the next nine months, the IANA transferred about two hundred million addresses to regional Internet registrars.

NRO assumes that the last block of addresses will be gone 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 appeared not yesterday, but at the end of the distant eighties, when the Internet showed signs of future avalanche-like growth.

Axel Pawlik, the head of the NRO, argues that this situation cannot but worry, and the only acceptable way out of this situation is timely (in the light of the latest news with timeliness, it somehow did not work) 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 top five recorders will allocate more than 2000 IPv6 blocks, which is 70% more than in 2009 .

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