Akamai To Offer IPv6 To All In April 110

Posted by Unknown Lamer from the lolcats-over-ipv6 dept.
netbuzz writes "Akamai says that it will offer IPv6 services to its entire customer base beginning next month – a long-awaited move that is expected to be a major boon to the adoption rate of the next-generation Internet Protocol. Akamai hoped to release its production-grade IPv6 services by the end of 2011, but the task proved more difficult than originally anticipated. Akamai has been beta testing its IPv6 services with key customers since last fall."

    Based on my own company checks for readiness I assume the big hold up feature parody with IP4 and IP6 security software and equipment.

    I know many of our security appliances have been able to route IP6 for a long time, but few of them could filter or manage the traffic with any sort of detail close to that of IP4 since the features had not been ported.

        How would it be any better? You still would have to replace equipment and software in order to support it. Most high-end equipment uses ASICs for routing, so you wouldn't be able to just do software upgrades to support it.

          IPv6 boosters are fond of this talking point, but "no backward compatibility" is a gross exaggeration, or to be precise it is a false dichotomy, when in fact the ability to preserve front end interfaces that are familiar to users and administrators is a form of backward compatibility. But that certainly would not be the only form of backward compabitility offered by an extended IPv4 stack.

          • The backward compatibility breakage happens right @ the IP header, where the sizes of the source and destination addresses are defined. So an application that looks for a source address @ bit 192 would now have to start looking @ bit 193. Similarly, if the address sizes were changed to even 33 bits, similar changes would happen @ the header, albeit different in magnitude, and every router in the world would still have to be reconfigured/redesigned, and every IP app would still have to be re-written.

            • Wah wah, we can't figure out where to put some more bits. There must be just no way. Right.

              • You can. Just that every system that deals w/ it has to know that there are more than just 32 bits to the addresses. And once they're all going to be retrained, it's no different from the sort of effort that IPv6 is going through. In fact, by now, IPv6 has the most widespread support of any standard except IPv4, and if anyone were to come up w/ something else, it would be way behind IPv6 as far as adaption goes.

                • Actually, you can pack extra bits into an IPv4 packet in such a way that a) valid packets using 32 bit addresses remain valid and b) packets with extra address bits are seen as invalid by unaware network drivers. Therefore "they" are *not* all going need to be retrained, only thoes that want to access a wider address range. So how much smoother that would have been rollout wise? We would already be there by now if a sensible approach like this had been adopted instead of the throw out the baby with the bath

                  • Where do you specify that? The IPv4 header ends w/ the destination address, and then the payload starts - the type of message, code, checksum, identifier, sequence number and then actual data. Before source address, there was version#, type of service, length, identification, flags & offsets, time to live, protocol and checksum. So where exactly do the extra address bits go? Oh, and remember, it will be needed for both source and destination.

                    Okay, let's say it was expanded to 40 bits, and we calle

                    • Nice straw man. You assumed that an some of the bits of an extended address could be interpreted as a valid address and nasty things would happen. But these nasty things will not happen if an IPv4+ packet with extended addresses is constructed to appear invalid to an unaware network driver. So basically you could have saved typing your last two paragraphs.

                      Your question of where to put the new addresses bits is constructive. The obsolete [ietf.org]stream id option seems like a reasonable candidate, providing additional

An unaware network driver could just read what's in the source and destination addresses, and ignore the areas that have the extended addresses - particularly if it happens to fall within a deprecated area in the header. Which is why the new addresses created would have to be compatible w/ what currently exists, thereby capping the growth headroom mentioned.

                    • So the principle is this: two extended address bytes are tucked away in places that will not destroy the internet. Such packets are constructed to appear invalid to unaware applications. If a path exists between a source and a destination both supportting extended addresses then the source and destination can communicate in the extended address space. The new byte goes at the least significant end, not the most significant, so that routing databases do not need to change.

                      These ideas really boil down to the failure to understand the issue is not about IP headers, packet formats or finding clever places to put things.. It is about ADDRESSING.

                      If the address spaces between IP protocols overlap then nobody knows apriori what paths support which protocols. We can not know if host A communicating via IPv4 can also reach host B on IPvDP or what router along the path prevent host A from communicating with Host B .

What if the host was down or routing changed thru a router without support for IPv4+..how do you know? How does it work?

                      To connect to an unaware IPv4 host, host B needs some help from a NAT. This is where having the fifth byte on the low order end is really helpful: the NAT does not need to be stateful and does not need to delve into protocols. It just needs to manage its pool of dynamic IPs as dynamic IP shemes already do.

                      It most certainly needs to keep state... 1 real IP shared by a bunch of fake (IPv4+) IPs requires state to manage the 1:many association on the real IP.
