Re: New addresses for b.root-servers.net
by Terrence de Kat 13 Jun '23

13 Jun '23

Forgive me if I'm missing something obvious, but why are you renumbering at all? Of course the diversification of RIRs is a good thing, but couldn't that be accomplished just as well by transferring the current allocation to LACNIC? It seems to me that there are a lot of reasons why, when it concerns root servers, renumbering should be a last resort. Especially when you already renumbered relatively recently and when an administrative solution rather than an operational one is available. I administer a few public IRC servers for EFnet, and when I assign a /24 for such a server I consider the subnet unfit for any other purpose from that point forward. Practically lost for normal use. Now, a DNS root server is obviously not the same as an IRC server, but I'd guess that there is a lot in common concerning threats and mitigation of those threats. Only the scale is much larger and the service (much) more critical (though people on IRC will fight me for saying that :). So, it seems to me that you'd also like to avoid renumbering unless absolutely necessary, if only because it's a waste of a perfectly good subnet. NB. Apologies for top-posting, a script that is supposed to fix this is started corrupting my emails after an update and I haven't been able to find the problem. -- Regards, Terrence de Kat, PhD/MTh/BPsy Darkness Reigns (Holding) B.V.

Do ISP's collect and analyze traffic of users?
by Michael Thomas 12 Jun '23

12 Jun '23

And maybe try to monetize it? I'm pretty sure that they can be compelled to do that, but do they do it for their own reasons too? Or is this way too much overhead to be doing en mass? (I vaguely recall that netflow, for example, can make routers unhappy if there is too much "flow"). Obviously this is likely to depend on local laws but since this is NANOG we can limit it to here.

Seattle Scavenger Hunt
by Wade, Clara 11 Jun '23

11 Jun '23

Hello Fellow NANOG 88 Attendees, We saw some of you would like to get to know Seattle better. Our DEI committee put together a fun activity for you to do this while also getting to know some other community members. We will be going on a scavenger hunt to uncover Seattle’s charms, gems and modern marvels. Teams will be put together to complete challenges and earn points along the way. The leaderboard will show live scores and winners will be announced on Wednesday at the end of the conference. In order to put the teams together, we will need you to please fill out this form<https://forms.gle/kZMkDzTqCM6KpktV7> indicating which time slot works best for you and any affinity groups that you identify with. We look forward to seeing you there! The NANOG DEI Committee

Seattle NANOG 88 things to see
by William Herrin 10 Jun '23

10 Jun '23

Howdy, We're a couple weeks out from NANOG 88 so I thought I'd repost a list of things I think folks with computer and engineering backgrounds might enjoy doing up here in Seattle. 1. The Connections Museum is a must-see for telecom enthusiasts (which I assume you are since you're attending a NANOG meeting). Six different phone switches (some electromechanical) and a boatload of other telecom stuff taking up a floor and a half of a "central office" building. In good working order. You can see and, to some extent, touch. https://www.telcomhistory.org/connections-museum-seattle/ Beware: It's only open on Sundays from 10 am to 3 pm, so if you want to check it out, you'll have to come in early for it. 2. The monorail (https://www.seattlemonorail.com/) is a well maintained German-engineered 1960s vision of the future. Departs from Westlake Center about 3 blocks from the hotel. Runs to the Space Needle and MoPop (the Museum of Popular Culture) which are also worth seeing. Both the monorail and space needle were built for the 1962 World's Fair. Buy tickets for the Space Needle the day before. Sunset is particularly nice. 3. Snoqualmie Falls Hydroelectric Museum and power plant https://www.pse.com/en/pages/tours-and-recreation/snoqualmie-tours Beware that Snoqualmie Falls is a half hour or so outside of the city. 4. Northwest Railway Museum (also near Snoqualmie Falls) https://www.trainmuseum.org/ 5. Museum of Flight (this is Boeing's home town, so it's a high quality aircraft museum) https://www.museumofflight.org/ 6. Pike Place Market, about 10 blocks from the hotel, is a Seattle icon. 7. Mt. Rainer, if you want to check it out, is a full-day trip: 2.5 hours to get there, 2.5 hours to get back plus the time you spend in the park. They finally cleared the snow from the roads last weekend so it's open but it's too far to catch it in an afternoon. Decent odds of getting a shirtsleeves on the snow pack picture like this one: https://bill.herrin.us/pictures/20210627-rainier/img-20210627-145745.jpg If you've been to Rainier before, Diablo Lake, Cascades National Park and Washington Pass in the opposite direction are also beautiful. Some things to know about Seattle: * Summer weather is good weather in Seattle. Expect sunshine, mild to warm temperatures in the day, crisp in the morning. Light if any rain. 5 am sunrise, 9 pm sunset. * Downtown Seattle parking spaces are super-tight. If you rent a car, get a small one. * Seattle is -very- dog friendly. You'll encounter our generally well-behaved canine companions on the street, in stores and possibly even in the hotel and event venues. Pack your allergy medication if you need it.

bfd & IPv6 on Cisco 4948E-E / IOS 15.2
by Jason Canady 09 Jun '23

09 Jun '23

I am attempting to setup bfd with IPv6 on Cisco 4948E-E running IOS 15.2. bfd on IPv4 works great, but I'm having troubles with IPv6 and spent hours on it. The trouble exists whether I use OSPFv3 or BGP. Each side transmits, but the other side doesn't receive. Same interface works fine on IPv4. Any and all help would be appreciated! Using this on the interface of each switch: ospfv3 1 bfd ospfv3 1 ipv6 area 0 ospfv3 1 ipv6 bfd bfd interval 500 min_rx 500 multiplier 40 #show bfd neighbors details IPv6 Sessions NeighAddr LD/RD RH/RS State Int FE80::A2EC:F9FF:FE2B:B33F 68/0 Down Down Te1/52 Session Host: Software OurAddr: FE80::BA38:61FF:FE65:20BF Handle: 1 Local Diag: 0, Demand mode: 0, Poll bit: 0 MinTxInt: 1000000, MinRxInt: 1000000, Multiplier: 40 Received MinRxInt: 0, Received Multiplier: 0 Holddown (hits): 0(0), Hello (hits): 1000(566) Rx Count: 0, Rx Interval (ms) min/max/avg: 0/0/0 last: 23068067 ms ago Tx Count: 566, Tx Interval (ms) min/max/avg: 756/1000/875 last: 268 ms ago Elapsed time watermarks: 0 0 (last: 0) Registered protocols: OSPFv3 CEF Last packet: Version: 1 - Diagnostic: 0 State bit: AdminDown - Demand bit: 0 Poll bit: 0 - Final bit: 0 C bit: 0 Multiplier: 0 - Length: 0 My Discr.: 0 - Your Discr.: 0 Min tx interval: 0 - Min rx interval: 0 Min Echo interval: 0 #
