Hi guys, I'm just curious about the creation of ip v6 addresses, I heard somewhere that it was because we ran out of ip v4 addresses. In which case I am wondering why we didn't have ip v5 addresses? Thanks, its just out of curiousity
Technically speaking, IPv5 never existed.
After IPv4, there was an experiment with the Internet Stream Protocol (V.2). During this experiment, they used a 5 as a header to it's packets, to difirentiate it from 'normal' packets.
Although that protocol never saw the light outside of the testing phase, it was decided that the next IP protocol would be 6, just to avoid confusion between them.
