Current State of IPv6

Due to the number of limited number of internet addresses, a new internet protocol has come available to consumers, IPV6. “Internet Protocol version 6 (IPv6) is the latest revision of the Internet Protocol (IP), the communications protocol that routes traffic across the Internet. It is intended to replace IPv4, which still carries the vast majority of Internet traffic as of 2013” (IPv6, 2013).
The Internet has experienced an astonishing increase of devices accessing the Internet. Because of this increase, IPv4 addresses are running out. The solution is for IPv6 to accommodate this increased demand by providing a much larger address space, along with improved traffic routing and better security. There are several advantages and disadvantages with IPv6. Some advantages are:
IPv6 provides more address space, which is being needed in larger business scales, such as: Comcast. It is a more powerful internet (128bit versus IPv4's current 32 bit). It offers and overall larger scale internet, which again will be needed in the future. Address allocation is done by the device itself and support for security using (IPsec) Internet Protocol Security. IPv6 includes plug and play, which is easier for novice users to connect their machines to the network. Essentially, configuration will happen automatically. Some disadvantages are: It will be much harder to remember IP addresses (compared to the addresses now). It is not easy creating a smooth transition from IPv4 to IPv6. IPv6 is not available to machines that run IPv4. The cost in having to replace an IPv4 machine and the time to needed to convert over to IPv6. It is not so widely used by residential internet service providers.
