IPv6 on Lumen/CL
by Nathan Anderson 29 Aug '22

29 Aug '22

We have a circuit on AS209 that was originally provisioned v4-only. I'm now trying to get Lumen to turn v6 up on it. How long does this typically take? I've had a configuration ticket open for nearly 3 biz days now with no movement (or even acknowledgement). For anybody who has gone through this with them, is this unusual or nah? When they do get around to it, what can I expect in terms of how they will prefer to set this up? Separate BGP session running over v6 itself, or modify existing session to have it also carry v6 NLRIs? Thanks, -- Nathan

VZ FIOS and Intel TCP IPv6 Checksum Offload problems
by Sean Donelan 29 Aug '22

29 Aug '22

Hopefully, my pain will help someone else. I've had sporadic Internet slowdowns and stuck networking since IPv6 was enabled on my FIOS ONT a few months ago. After too much troubleshooting, I found out some older Intel GbE ethernet cards have a IPv6 Checksum Offload incompatibility with certain fiber ONT terminals. As Verizon is enabling IPv6 on its FIOS network, you might find intermittent network problems. Intermittent are the worst kind of problems. In some situations where a client machine is connected via some specific Optical Network Terminals (ONTs), and data is appended after the packet checksum, the network adapter can drop receive packets when using TCP-IPv6 Checksum Offload for receive traffic. Intel published an alert in 2017, but I didn't have IPv6 on FIOS then. https://www.intel.com/content/www/us/en/download/19174/disabling-tcp-ipv6-c… TLDR; turn off TCP IPv6 Checksum Offload Affects all operating systems (Windows, BSD, Linux, etc) using the affected wired Intel ethernet controllers. Not a problem with Intel WiFi.

email spam
by William Herrin 28 Aug '22

28 Aug '22

Hello, To folks at places like Google and Godaddy which have gotten, shall we say, overzealous about preventing spam from entering their systems, consider the risk: https://www.washingtonpost.com/education/2022/08/23/fairfax-county-counselo… "Chesterfield County police said emails notifying Fairfax County Public Schools that an employee was arrested and charged with soliciting prostitution from a minor were not delivered to the school system." Long story short, the pedo kept his school job another year and a half. There was once a time when both the outbound emails and the bounce messages when they failed... worked. It was a spammy place but the important emails got through. Regards, Bill Herrin

Greetings, Anyone with the FAA around by chance, needing to speak to someone regarding a circuit we provide to a specific VOR-DME. We normally deal with L3Harris though that avenue has gone unanswered. Appreciate any help anyone can provide. Luke

Having some experience with documents of extreme public interest, and web sites getting overloaded (Starr Report on President Clinton, 1998)... its nice to see government web sites still get overloaded several decades later. "PACER Service Under Fire After Trump Affidavit Crash Reports" PACER is the electronic document system used by the U.S. Court System.

AS701 anycasts any IP?
by Bjoern Franke 26 Aug '22

26 Aug '22

Hi, while investigating an issue I was wondering a german IP was only 1-2 hops away from some RIPE Atlas Probes connected via AS701. It seems at least probe #50235 and #54508 see any IP directly as next hop, as an example here with the IP of mailop.org: https://atlas.ripe.net/measurements/44133927/ Regards Bjoern

Some Cox customers reported they were not able to reach one of our IPv6 prefixes, including more specifics announced by different ASNs. I suspect the whole range is blackholed or something. ``` mtr -r -c1 -w 2a12:dd44::1 Start: 2022-08-25T18:09:50-0700 HOST: ronsor-lg-arch Loss% Snt Last Avg Best Wrst StDev 1.|-- 2600:8800:3b80:3d70:424c:77ff:fe74:cf7a 0.0% 1 30.8 30.8 30.8 30.8 0.0 2.|-- 2600:8800:3bff:ffff::1111 0.0% 1 97.1 97.1 97.1 97.1 0.0 3.|-- 2001:578:801:fffc:600::2c 0.0% 1 15.3 15.3 15.3 15.3 0.0 4.|-- 2001:578:900:4::6 0.0% 1 13.8 13.8 13.8 13.8 0.0 5.|-- 2001:578:1:0:172:17:248:216 0.0% 1 73.5 73.5 73.5 73.5 0.0 6.|-- ??? 100.0 1 0.0 0.0 0.0 0.0 0.0 ``` 2a12:dd47:805e::1 originated from AS211233 dropped at the same router 2001:578:1:0:172:17:248:216.
