Ipv6

The IPv4 address space is nearing exhaustion. The unallocated address pool is currently expected to be depleted at the IANA level in June 2011, and at the Regional Internet Registry (RIR) level in January 2012. Networks will need to transition to IPv6, which allows for an astronomically larger address space (among other nice features). IPv6 has been around in some form since 1995. However, since network operators are human beings, the consensus has not been to methodically migrate to IPv6 over the last 15 years, but rather to procrastinate 15 years and then pull an all-nighter on the eve of exhaustion.
