Exactly the problem, and the reason A) IPv6 is not and will not be a viable option any time soon (soon being before the publication of an IPv6 NAT RFC), and B) why network providers (and other parties who stand to gain financially) are firmly against IPv6 NAT. > If we could get a true accounting of the extra cost imposed > by NAT's I would say it would be in the trillions of dollars. This is exactly the sort of hyperbole, like RFC4864's proposing that application-layer proxies are a viable substitute for NAT, that discredits IPv6 proponents. Those who remember the financial industry's push for SET, a failed encryption technology, will be struck by the similarities in technical vs rhetorical arguments. Perhaps what we need is an IPv6 NAT FAQ? I'm suspect many junior network engineers will be interested in the rational behind statements like: * NAT disadvantage #1: it costs a lot of money to do NAT (compared to what it saves consumers, ILECs, or ISPs?) * NAT disadvantage #2 (re: your IPv6 address space) Owned by an ISP? It isn't much different than it is now. (say again?) * NAT disadvantage #3: RFC1918 was created because people were afraid of running out of addresses. (in 1992?) * NAT disadvantage #4: It requires more renumbering to join conflicting RFC1918 subnets than would IPv6 to change ISPs. (got stats?) * NAT disadvantage #5: it provides no real security. (even if it were true this could not, logically, be a disadvantage) OTOH, the claimed advantages of NAT do seem to hold water somewhat better: * NAT advantage #1: it protects consumers from vendor (network provider) lock-in. * NAT advantage #2: it protects consumers from add-on fees for addresses space. (ISPs and ARIN, APNIC, ...) * NAT advantage #3: it prevents upstreams from limiting consumers' internal address space. (will anyone need more than a /48, to be asked in 2018) * NAT advantage #4: it requires new (and old) protocols to adhere to the ISO seven layer model. * NAT advantage #5: it does not require replacement security measures to protect against netscans, portscans, broadcasts (particularly microsoft netbios), and other malicious inbound traffic. IMHO, Roger Marquis

RFC1597 is dated 1994 and I thought the earliest references were 1995/96. The point I was trying to make is that RFC1918 and precursors were not motivated solely by address space limits. They were also motivated by the increasingly common practice of numbering internal networks with unassigned public address space. Random assignments of IP blocks had begun years before RFC1597 and were occurring in increasing numbers. "Those who forget history are doomed to repeat it" or so the saying goes. Force consumers internal networks to be publicly routable and you will see history repeat itself. Roger Marquis

No, it's because neither need to do it.

We have ADSL users with v4 and v6, they mostly use low end Ciscos, 837 and such (cheap on ebay so for the tech user base it's not too hard) Cheap retail CPE adding v6 by default would help. James W.

Private use of non-RFC1918 IP space
by Trey Darley 05 Feb '09

Hi, y'all - Some colleagues and I are running into a bit of a problem. We've been using RFC 1918 Class A space but due to the way subnets have been allocated we are pondering the use of public IP space. As the network in question is strictly closed I don't anticipate any problems with this as the addresses would be unambiguous within our environment. I'm curious if anyone else is doing this. I'd be very interested in corresponding off-list with anyone who's in a similar position. Cheers, --Trey ++----------------------------------------------------------------------------++ Kingfisher Operations Trey Darley - Principal

If you're going to add a prefix at least do it properly get PI, keep PA as PA only. No PI too hard excuses. If there were global stricter filtering at allocations then the hijacking problem would be one less excuse for people to justify crazy deaggregation brandon
