90% of IPv4 Addresses Have Been Taken

Nine out of ten IPv4 internet addresses have been assigned. Every devise that connects to the internet needs to have an address to work. The problem here is obvious, but the solution is not that complicated. Companies/governments need to switch over to the IPv6 protocol. Current estimates give them about three years to complete the transition or we could see some major problems.

Before you start running around in panic, the world has seen a 30% increase in IPv6 allocations in 2009 so there might be hope that governments, vendors, enterprises, telecoms operators and you get to switch before it’s too late!"
