    Do we really need IPV6? Sure alot of computers are out there but most of them are behind routers so there is only one IP address per router (If I am understanding and it's very likely I am not) and because of that you can cut down the number of IP addresses by thousands.

    Yes, we really do! IPV4 has a maximum of something like 4.2 biliion addresses (after you take out unusable addresses). If you just consider the publicly exposed addresses, that is still a dangerously high number of addresses that are used - and worse, there is a lot of extra obscure/clever/confusing ways to break up those subnets. So, we are running out of addresses, we are resigned to using wacky methods to make the addresses we do have, usable in our environments..

    Meanwhile, IPV6 has a maximum of something like 340,282,366,920,938,463,463,374,607,431,768,211,456 addresses.

    Seems like changing over is a small price to pay to "never" having to worry about IP addresses allotment again, I think!
