All networking specialists need to be familiar with IPV6 because it is the future of networking. So why are new homes and offices still being fitted with IPV4?
IPV4 has 43 x 109 (4.3 billion) addresses, hard to imagine anybody thinking that it would reach that capacity within a lifetime. IPV6 has 3.4 x 1038 (340 undecillion) addresses. Do you think that we will run out of IPV6 addresses anytime soon? How long will it be before we have to create IPV7 and IPV8?
