Re: So...
said by Jerm  :Advantage: 128bit addresses instead of 32bit allow for trillions of addresses (ie bye-bye NAT!) Disadvantage: You now have to remember 2001:0db8:0eff:87a0:27bf:0000:1428:57ab instead. loss of NAT concerns me greatly. atm ISPs charge per IP address(the main reason for homes to have NAT routers). id imagine it is a perfectly safe guess they would still charge huge amounts of money for more then one IP even if NAT was made obsolete by IP6 and they had the room for every device in every home they serve to have an IP. |

| ISP's charge per ISP because they can....but also because IP addresses are at a premium because they are in limited supply. ISPs also may only have a limited block of addresses that they can allocate so in order to ration them, they charge extra.
With IPv6, all the supply issues go away. A 128 bit address space, you literally could give an ip address to every grain of sand on the planet and still not run out. Every person/subscriber in the world could get their own block of 1K addresses to allocate as they want and there would still be more addresses then anyone knows what to do with.
Now that doesn't mean that ISPs won't still charge for them, but they won't be able to use the excuse that they are in limited supply. Dynamic addresses also could go away . It would only be a matter of the ISP updating their router tables for new customers as they sign up. |

Hmm BYE BYE to claims by the ISP's they don't know who the IP addres belong to........US poor P2P Pirates that are P2P'ing Ubuntu Linux OS's, World of Warcraft updates, Joust, and Vuze and others can't hide no more.  |

The same reasons why ISPs don't track DHCP users now will exist with IPv6...they choose not to. It's a headache for them not only from a technological reason, but also with record keeping, legel requests, etc. It's much easier to turn a blind eye, shrug your shoulders, and say "Sorry, we don't keep track of that" then deal with all the crap if they did. Just like most businesses, if it costs them money and it's not required, they aren't inclined to do it. |
