| IPv4 | 147.189.216.0/21 ( 147.189.216.0 - 147.189.223.255) | Grèce | Antonios A. Chariton | The BGP Clock Every 1 hour the prefix 147.189.(216+N).0/24 is advertised. The N here is calculated as HH % 8, so the hour in 24h format modulo 8. Naturally, UTC is used. The prefix is withdrawn 10' after the advertisement. At most one /24 should be available at any single time, which means that all 8 prefixes of the /21 rotate 3 times a day. At 00:00, 147.189.216.0/24 is advertised, at 00:10 it is then withdrawn, then at 01:00 147.189.217.0/24 is advertised, which is in turn withdrawn at 01:10, and so on. Why? We are conducting research on BGP Stuck Routes to better understand how they happen, when, which equipment is more buggy, etc. We also want to understand them better. As this is a beacon, anyone can study the results using RIPE RIS, or any other source like RouteViews. Feel free to take a look and let everyone know if something interesting ever comes up! An example of research presented at RIPE 89 & 91 is here: https://ripe89.ripe.net/wp-content/uploads/presentations/8-BGP-Zombies-RIPE89.pdf https://ripe91.ripe.net/programme/meeting-plan/sessions/19/87WNTB/ On 2025-11-17 11:40-12:00 UTC there was a change from origin AS4601 to AS210312 with ROA and route{6,} object changes. We are also studying the propagation of BGP Communities with this beacon, to minimize the count of BGP UPDATEs generated. At origin, all prefixes are tagged with the following values: BGP Legacy Communities: (4492, 64700) (4601, 64700) BGP Extended Communities: (ro, 4492, 1337) (ro, 4601, 1337) (ro, 210312, 1337) BGP Large Communities: (4492, 64700, 1337) (4601, 64700, 1337) (210312, 64700, 1337) For any more info or collaboration, find me using the Contact page at daknob.net :) Geofeed https://geo.daknob.net/as210312.csv |
