Scaling up the Internet from IPv4 to IPv6

“

- When IPV4 was created, it supported over four billion devices that could connect to the internet. However, as more and more devices were created, the number of available addresses started to run out. So another way needed to be created. Luckily, the internet protocol's designed to scale and expand to meet new demands. So in 1995, a new version of the internet protocol was created, it's called IPV6. Now you might ask yourself, what happened to IPV5? Well, part of how specifications are developed is that new ones could be created and designed, but when they get to a certain point they're given a name. In 1979, an experimental protocol called the internet stream protocol was assigned the number five, but it was never finalized. In 1995, the Internet Engineering Task Force, or IETF, needed to create a new way to provide addresses on the internet, now to expand beyond the four billion limit of IPV4. The result was to increase the number of bits used to store an address. IPV4 uses 32…
