Did you know that we are running out of IP addresses? The internet is growing constantly and due to a major economy and internet boom in China and India we will soon be running out of IPv4 addresses, IPv6 addresses will be the new standard. The countdown to IPv4 exhaustion is ticking!
IPv4 vs. IPv6
IPv4 is using 32-bit addresses, so overall there can only be 2^32 addresses. Of course 4,294,967,296 (32^2) is a large amount of addresses, but considering that for example the amount of internet users in China is growing by 6% every year, experts have been worried about IPv4 exhaustion since the 80’s. IPv6 will be using 128-bit addresses and will therefore have a much larger address space.
Internet Users USA vs. China
The USA had about 227,719,000 internet users (75% of the population) in 2009, according to internetworldstats.com. The internet users in China increased from 137,000,000 in 2007 to more than 360,000,000 in 2009 (cnnic.cn).
