ARIN Election
by Nicholas Warren 04 Oct '23

04 Oct '23

Does anyone know how many people will be elected from each category? I don't regularly keep up with everyone's business. So, are any of candidates overachievers or, well, underachievers? Nich Warren

Re: maximum ipv4 bgp prefix length of /24 ?
by Jakob Heitz (jheitz) 03 Oct '23

03 Oct '23

Among the issues: Suppose the FIB has all the /24 components to make a /20, so it programs a /20. Then one of the /24's changes nexthop. It now has to undo all that compression by reinstalling some of the routes and figuring out the minimum set of /21, /22, /23, /24 to make it happen. Then to avoid a transient, it needs to make before break. Quite a bit of FIB programming needs to happen just to modify a single /24. Then the next /24 in the set also modifies its nexthop. and so on for 100000 routes. All because a peer link flapped. Affecting convergence. Then you need to buy a line card that can hold all the individual routes, because you can't always compress, because not all the routes in your compressed set have the same nexthop during a transient. Finally, it's all nicely compressed. Now what? You have lots of empty slots in your FIB. I'm sure lots of nerds can come up with transient reduction algorithms, but I'd rather not. Kind Regards, Jakob --------------------------------------------------------------- Date: Sat, 30 Sep 2023 20:04:29 -0700 From: Owen DeLong <owen(a)delong.com> Not sure why you think FIB compression is a risk or will be a mess. It?s a pretty straightforward task. Owen

maximum ipv4 bgp prefix length of /24 ?
by VOLKAN SALİH 02 Oct '23

02 Oct '23

hello, I believe, ISPs should also allow ipv4 prefixes with length between /25-/27 instead of limiting maximum length to /24.. I also believe that RIRs and LIRs should allocate /27s which has 32 IPv4 address. considering IPv4 world is now mostly NAT'ed, 32 IPv4s are sufficient for most of the small and medium sized organizations and also home office workers like youtubers, and professional gamers and webmasters! It is because BGP research and experiment networks can not get /24 due to high IPv4 prices, but they have to get an IPv4 prefix to learn BGP in IPv4 world. What do you think about this? What could be done here? Is it unacceptable; considering most big networks that do full-table-routing also use multi-core routers with lots of RAM? those would probably handle /27s and while small networks mostly use default routing, it should be reasonable to allow /25-/27? Thanks for reading, regards..

new net neutrality/title ii mailing list
by Dave Taht 01 Oct '23

01 Oct '23

Since network neutrality and title ii regulation is back in the news, and the issues so fraught with technical and political mis-conceptions, I have started a new mailing list to discuss it, and try (for once) to feed back valid techical feedback into the FCC´s normal processes. I kind of expect some EU-derived regulatory ideas to emerge, in particular. Sign up here: https://lists.bufferbloat.net/listinfo/nnagain The FCC chair has put out the following statement, and is circulating a proposed NPRM to be released Oct 19th. https://docs.fcc.gov/public/attachments/DOC-397257A1.pdf ... There is another FCC effort on a cybersecurity label due october 6th, which amazingly, a FCC commissioner had reached out to hackernews on, and got back loads of wonderful feedback. https://news.ycombinator.com/item?id=37392676 -- Oct 30: https://netdevconf.info/0x17/news/the-maestro-and-the-music-bof.html Dave Täht CSO, LibreQos

Seattle-area centurylink (residential fiber) on the list?
by William Herrin 29 Sep '23

29 Sep '23

Howdy, Is anyone from Centurylink in the Seattle area on the list? Would you mind contacting me offlist? My residential fiber has been bouncing for a few hours. I figured it was something physical and scheduled a technician, but on closer examination I'm seeing something weird with the PPPoE. It chugs along happily for a while (dc:38:e1:cd:4f:7a is you, 44:1e:a1:44:70:3f is me) and then I lose *my* connectivity for 10-20 seconds but during that window there's a big spew of packets that aren't addressed to me. The following is just the PPPoE LCP messages captured by tcpdump, but the misdirected traffic also appears to include TCP/IP user data for customers who are not me. 20:15:13.278955 44:1e:a1:44:70:3f >
