Re: There Might Be An Alternative

But it does NOTHING to the routing table issue, which is ANOTHER thing addressed by IPv6 AND one with real-world consequences. Because of the IPv4 address shortage, the organization of the addresses got thrown out the door. Basically, you can't be sure an address starting in 109 or whatever goes to the same physical region anymore, and if you're an upstream router, that means your routing tables just got complicated. Sure, the telephone exchanges have to deal with this now, but their problem isn't of the same scale. Instead of millions of requests an hour, it's per minute. The end result is increased latency all throughout the Internet, multiplied by each hop the packets have to make. So there's more problems to IPv4 than just address exhaustion.
