IPv6 is the next generation of internet protocol.  Since the internet was invented, we've been using IPv4; however, on February 3 of this year, the IANA (Internet Assigned Numbers Authority) gave out its last five /8's of IPv4 address to RIR's (Regional Internet Registries).  Soon, there will be no more IPv4 addresses available.  Although this will not initially affect devices that already have IP addresses, it will affect any new devices that need access to the internet. 

The drastic increase in address size will aid in the spread of technology worldwide.  As technology continues to advance, more devices will need IP accessibility and IPv6 will provide that. &
