| − | IP version 4 is what's currently used by most network devices. However, with more and more computers accessing the internet, IPv4 addresses are running out quickly. Just like in a city, addresses have to be created for new neighborhoods but, if your neighborhood gets too large, you will have to come up with an entire new pool of addresses. IPv4 is limited to just 4,294,967,296 addresses. IP version 6 is the replacement for the aging IPv4. The estimated number of unique addresses for IPv6 is 340,282,366,920,938,463,463,374,607,431,768,211,456 or 2^128. <ref name="What is My IP">http://www.whatismyip.com/faq/what-is-an-ip-address.asp</ref> | + | IP version 4 is what's currently used by most network devices.
