⚠ 1 MOAS-префикс — обнаружены ASNs с множественным происхождением

Все MOAS-аномалии →

Ранее стабильный префикс, исходящий от AS3910 теперь также объявляется другой ASN (MOAS — Multiple-Origin AS), обнаруженный нашими коллекторами RIPE RIS. Часто это безопасно (anycast, многодомность или недавняя передача) — но может сигнализировать об утечке маршрута или захвате префикса, поэтому стоит проверить.
