IPv6 will increase the number of numerical addresses massively, increasing capacity to 340 billion, billion, billion, billion numbers. This should allow for virtually any number of new computers or devices to be connected to the internet in the future. IPv6 will also introduce reliability and security enhancements.
- spammers can get away with it because they're untraceable,
- reason: they send / relay spam from dynamic IPs,
- there's lots of dynamic IPs in use 'cos there aren't enough static IPs to go round,
- IPv6 will give us zillions more IPs,
- so let's give every computer in the world a static IP and make them all traceable and accountable,
- end of spam
(I hope)
