Re: How long will it take to completely get rid of IPv4 or will it happen at all?
It is true - you I have had to throttle back for years for optimum transport on many carriers. In fact, if you have an ATT transit in your mix of BGP you wont get a ping response at 1500 MTU from that ATT router.

CDNs for carriers

Re: CDNs for carriers
Simple flows wouldn't necessarily tell you if you're pulling a bunch from a Netflix caching box on your upstream somewhere. You'd think you had a huge amount going to your current upstream because technically you do, but a local cache or peer could alter that significantly. As we've been starting up our IX, we're finding that we can send lists of ASNs and prefixes and the various CDNs will tell us how much traffic they see going to our customers. Combine that with what flows tell you and I think you've got a good approach. What are some good approaches to determining traffic levels to not only ASNs, but also that ASN's downstream ASNs? You may have ASNs A, B, C, D and E in your flows. Say none of them represent more than 5% of your traffic by themselves. If B, C, D and E all purchase transit from A and you can reasonably peer with A, you actually can move 25% of your traffic over to a peer. Maybe there is no good approach at doing that without a bunch of manual work or paying someone else to do it. Looking at some stats from one of our customers that is also going through Equinix Chicago, for their average inbound ~37% of traffic was Netflix, Google was 34% and the next highest was Apple at 5%. Note that Akamai had left Chicago Equinix by this point, so they wouldn't be reflected in those numbers. Those percentages are percent of all traffic they send to Equinix. I believe about 2/3s of their total transit went to Equinix when that got turned up. Their total traffic went up once joining the Equinix IX, presumably because they were now bypassing some congestion somewhere. - Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com - Original Message - From: Jared Mauch ja...@puck.nether.net To: Christopher Morrow morrowc.li...@gmail.com Cc: nanog list nanog@nanog.org, Ramy Hashish ramy.ihash...@gmail.com Sent: Monday, June 29, 2015 8:44:18 AM Subject: Re: CDNs for carriers On Jun 29, 2015, at 9:33 AM, Christopher Morrow morrowc.li...@gmail.com wrote: On Mon, Jun 29, 2015 at 8:53 AM, Ramy Hashish ramy.ihash...@gmail.com wrote: do you have any figures about how much this recommended CDN save from the Internet BW? isn't that going to wholey depend on your traffic mix/matrix?

NTT's customer Sofia Connect leaked our routes to NTT. NTT accepted these routes instead of properly filtering their customer announcements. As a network of non-trivial size, announcing over 75,000 customer routes which is nearly 15% of the IPv4 routing table, we'd expect the common courtesy of having our ASN included in their customer facing AS-PATH filters, as we extend this same courtesy to other networks of this size (such as AS2914).

Re: NTT-HE earlier today (~10am EDT)
Greetings, We are aware of this issue and as is usual we filter customers based on their registered routes. This creates some unique challenges that we have been speaking about publicly and privately with various groups. I have started the process (yay telco-speak) to fix this. It would be helpful if networks would take a look at what routes they have registered in the various IRRs as well as if their AS-SETs expand out to something quite large. We have seen many customers import objects that then import their other upstream networks. We have found the IRR Explorer tool helpful to look at who has registered our IP space and to police these registrations with the various IRRs out there. http://irrexplorer.nlnog.net/ http://irrexplorer.nlnog.net/prefix/184.105.213.86 The stability of the routing ecosystem is something that I personally care a lot about and have privately given Mike and others my cell number to allow them to follow-up.

Re: OK, Google. Time to dial back the AI hype.
Because Google is an ISP, it seems to me a legitimate discussion point. Given Google's penchant for crafty customer surveillance, this technology seems like one that Google might try to leverage into a snoopy product. . if we wasted this list discussing things which *might* be leveraged into a snoopy product we would be overwhelmed and the folk who actually manage networks would go elsewhere. try some other list, please. we're just trying to move packets. randy

Re: How long will it take to completely get rid of IPv4 or will it happen at all?
Hi, I just ran a tcpdump looking for NTP packets going to 128.173.14.71. In 90 minutes, I got hits from 330 unique IP addresses, including some that were chatty enough to indicate there were dozens of hosts behind a NAT. ah yes. the joy of the usual 2 scenarios 1) your IP got used in some random equipment config/firmware 2) your IP got used in some documentation rather than using one the official IPv4 documentation address space the last scenario is the IP address was used in some long ago post or blog that google helps unearth whenever anyone asks for NTP. we had the same for DNS.learnt that lesson :/ without bothering to sanity check if a clock is still usable THAT is the scary part.they're not even checking its working (at least their kit wont crash and burn at the leap second if it hasnt got working NTP ;-) !) alan

(Oh, the initial frame size was selected for 3-mbit Ethernet so that collision mitigation was reasonable.) Think about jumbo frames (9000 bytes) and their robust error detection. Research is being done in even larger frames, because the rule is that as your transmission rate increases, you should increase the frame size and use a FRC algorithm that detects all one-bit errors and most two-bit errors, at least.

Things like IPX and token-ring are still around. IPv4 isn't going anywhere for decades. (if ever) Mostly because there are things that will *never* run IPv6 that aren't going to get replaced just because of IPv6. (it's a given most of those things don't live on the internet.)

It isn't dead yet, but it's certainly on the endangered list. Why did it die? The death of Novell NetWare (and their transitioned to IP) killed it the enterprise. Games adopting IP for network play killed it in the home. Ultimately, it sucks as a WAN protocol, so the internet was built using this new fangled IP thing.

And, depending on the network, have for eons. Have you checked the IP used by your cellphone? (the last few times I bothered to look... somewhere in 29/8. I thought that was really funny.) Why? Simple: Money. It's cheaper to install a $100k NAT appliance (or several) than it is to replace 16mil CPE devices, plus all the engineering, testing, and customer support training (read: BS scripts to follow.) AND, your customers aren't having any trouble getting where they need to go. Sure, there will be the forward thinkers pushing for IPv6, but not because there's some IPv6 only place they need to go (or be.)
