Can Large Scale NAT Save IPv4?

Julie188 writes "The sales pitch was that IPv6, with its zillions of new IP addresses, would eliminate the need for network address translation altogether. But Jeff Doyle, one of the guys who literally wrote the book on IPv6, suggests that not only will NAT be needed, but it will be needed to save IPv4 at the tipping point of IPv6 adoption. 'I've written previously that as we make the slow — and long overdue — transition from IPv4 to IPv6, we will soon be stuck with an awkward interim period in which the only new globally routable addresses we can get are IPv6, but most public content we want to reach is still IPv4. Large Scale NAT (LSN, also known as Carrier Grade NAT or CGN) is an essential tool for stretching a service provider's public IPv4 address space during this transitional period.'"

    what socialist utopia are you living in where it's ANYONES RESPONSIBILITY to offer a different version of a still functioning system?

    if you consider what i'm doing to be talking, then you can safely assume that i am money.

    if someone whines and then someone whines about whining, would you ever only question the 2nd whiner?

    the only moot point is that whining is pointless.

    The only thing worse than niggers are the dune coons. Motherfuckin Islam assholes. Throw pork at all of them, preferably raw. Put a few greased-up pigs in their mosques. Tell them if they don't like America, get the fuck out. I like that better than them out-breeding the local population like they're doing in France and throughout the UK. Let's burn some Korans. Oh and shut down the ground-zero mosque. Throughout history the Muslim dune coons have celebrated their victory over their enemies by either erecting a new mosque in conquered terrain or by taking over i.e a Christian cathedral and converting the building to a mosque. Fuck the dune coons. You see how the Middle East is nothing but constant war and no semblence of civilization? Well that's what happens when the dune coons are running things. Fuck Islam, fuck these violent assholes, fuck their religion, draw cartoons of the prophet Mohammed, show some titties to piss off the imams, and shit on the Koran today.

    Islam: It spreads like a virus because it is a virus.

    how about get a new ISP... how about start your own ISP?

    there was a time when americans knew how to overcome limitations placed on them by others.

    you are pathetic.

    so those people who overcame the limitations when there were 0 ISPs, and created the ISP option you have today... how did they create that ISP? people today don't have the same option to create an ISP in the same way?

    what changed?

    i did not assume or state you were american. i dismissed your ignorance and then recalled the reason americans rose up to rid themselves of the company of idiots LIKE you.

    Me too. I look forward to having no NAT and changing the IPs in my internal network every time I use a different ISP.

    "Hmm, my internet connection failed, better connect the backup one. OK, now this ISP gives me xxx:yyy:zzz:xxyz::0 IP, so I now have to go and change the addresses of all my PCs, since they won't be able to access the internet. If only there could be some way to keep the internal IPs constant..."

    Currently, the internal IPs of my computers do not depend on which ISP I am connected to.

    Problem solved:

    http://en.wikipedia.org/wiki/Private_network#Private_IPv6_addresses

    Or you can simple ask for a /48 or /64 from your local numbering authority (ARIN, RIPE, etc) and be done with it.

    So you're suggesting a problem that can be solved by:

    Routing
    DNS
    Stateless Autoconfiguration
    DHCP
    or a shell script

    And decide that you'd rather keep NAT. How often do you have this problem anyways, and why are you using that ISP that keeps going down? And where's your IT department?
