Apple moved from CDN, and ARIN whois
by Denys Fedoryshchenko 24 Sep '20

24 Sep '20

Hi, Interesting, it seems AS6185 moved traffic from all CDN to their own content network. I noticed big spikes in traffic and complaints about slowness, figured out, Apple content (especially updates) are not coming from a numerous co-hosted CDN, but became "live", congesting upstreams. So much efforts on collocating endless CDN in premises to keep things closer to users and handle traffic surges, and yet again, some companies keep inventing their own. P.S. I dont know if it is bug, but whois at ARIN return "No match found for n + 17.0.0.0/8" for 17.0.0.0/8, but works fine for single ip from this range, like 17.0.0.0, and returns info about 17.0.0.0/8

iOS 14 (Apple) DNS bits
by vom513 24 Sep '20

24 Sep '20

*** Hopefully this is on-topic enough for the list… Since iOS 14 has been released recently, folks have observed the changes to the network and DNS mechanics. I wanted to get some feedback from folks here on this. I have a small observation, and a slightly larger question: Observation: iOS 14 now seems to send 3 queries (up from 2) for every “socket” connection to a name. Whereas we’ve had A + AAAA for quite some time in many OS’es - on iOS 14 we now have A + AAAA + HTTPS (type 65). I doubt this will be any burden on anyone, but I just wanted to point out that now many Apple devices will have 1.5x the previous query traffic coming from them. I also wonder who is actually using HTTPS RR’s in their zones - I would assume Apple would be (soon at least) for their cloud and infra. services. Alas, I don’t see anything in Wireshark, nor do I have a command line utility that understands the RRtype to test by hand... Question: iOS 14 now flags networks that it believes are blocking encrypted DNS. It puts a warning in Settings for the wifi. For my home network this is expected. I redirect 53 to my own firewall - as well as use some RPZ feeds - one of which aims to block/poison DOH/DOT attempts. My question is how is it making this determination ? I log the iptables redirects, and I also log RPZ hits out of bind. I don’t see anything in my logs where my phone has tripped these. I don’t currently block 853/tcp (but I likely will) - so it shouldn’t be making it’s determination off of that… Does anyone *really* know how iOS 14 is testing this ?

Connecting networks across borders, and the world: A conversation with Alejandra Moreno + Joel Pacheco
by NANOG News 23 Sep '20

23 Sep '20

*“Here you can find mentors, friends, and colleagues who are willing to help you and share their knowledge.”* Everything Alejandra Moreno and Joel Pacheco do is centered on community, collaboration, and connectivity — from routing traffic to and from the MEX-IX, to peering relations and education with networks around the world. The two, who work together at MDC Data Centers in McAllen, Texas, first met while attending NANOG 70. We spoke with them recently about the role of empathy and a shared sense of purpose in staying connected during a pandemic; translating passion into action through one's professional work; and the importance of teamwork and mentorship in growing and evolving a career.

SRv6
by aaron1＠gvtc.com 22 Sep '20

22 Sep '20

I have what seems to be a good SRv6 test in my lab running XRv9k 7.0.2 But I'm wondering why the sniffer doesn't show the much-spoken-of SRH (Segment Routing Header).. But rather, shows my L3VPN v4 traffic riding v6 and that's it. Let me know if I'm seeing an SRH and just don't know it, LOL. Ethernet - Type 0x86dd Ipv6 - Next Header IPIP (4) Ipv4 - icmp echo (my tests ce to ce end to end) Those layers is all it shows. I've read a lot about SRv6 with SID's inside extension headers or segment routing header, but I'm not seeing it. Any idea what this is that I'm seeing ? I've configured the PE's IAW https://www.cisco.com/c/en/us/td/docs/routers/asr9000/software/asr9k-r6-6/se gment-routing/configuration/guide/b-segment-routing-cg-asr9000-66x/b-segment -routing-cg-asr9000-66x_chapter_011.html#id_95420 I can give you more info if you wish.

BFD for routes learned trough Route-servers in IXPs
by Douglas Fischer 22 Sep '20

22 Sep '20

Time-to-time, in some IXP in the world some issue on the forwarding plane occurs. When it occurs, this topic comes back. The failures are not big enough to drop the BGP sessions between IXP participants and route-servers. But are enough to prejudice traffic between participants. And then the problem comes: "How can I check if my communication against the NextHop of the routes that I learn from the route-servers are OK? If it is not OK, how can I remove it from my FIB?" Some other possible causes of this feeling are: - ARP Resolution issues (CPU protection and lunatic Mikrotiks with 30 seconds ARP timeout is a bombastic recipe) - MAC-Address Learning limitations on the transport link of the participants can be a pain in the a..rm. So, I was searching on how to solve that and I found a draft (8th release) with the intention to solve that... https://tools.ietf.org/html/draft-ietf-idr-rs-bfd-08 If understood correctly, the effective implementation of it will depend on new code on any BGP engine that will want to do that check. It is kind of frustrating... At least 10 years after the release of RFC until the refresh os every router involved in IXPs in the world. Some questions come: A) There is anything that we can do to rush this? B) There is any other alternative to that? P.S.1: I gave up of inventing crazy BGP filter polices to test reachability of NextHop. The effectiveness of it can't even be compared to BFD, and almost kill de processing capacity of my router. P.S.2: IMHO, the biggest downside of those problems is the evasion of route-servers from some participants when issues described above occurs.
