Affichage des 100 premières.

Sur Internet, les routes sont annoncées sous forme de préfixes : un système autonome indique à ses voisins via BGP qu’il peut acheminer le trafic vers, par exemple, 85.240.0.0/13. Cet outil recherche un préfixe dans notre copie quotidienne de la table de routage mondiale et montre trois choses :

Annonces exactes : quel AS origine exactement ce préfixe. Plusieurs origines (MOAS) sont normales pour les services anycast et certains réseaux multi-hébergés, suspectes sinon.
Routes couvrantes : des annonces moins spécifiques qui le contiennent. Le trafic suit la route la plus spécifique ; une route couvrante compte si la plus spécifique disparaît.
Routes plus spécifiques : des annonces à l’intérieur du préfixe, qui peuvent appartenir à d’autres réseaux (des clients – ou un détournement).

Pour chaque route annoncée, RPKI est aussi vérifié : une ROA autorise-t-elle son AS d’origine ?

La table est la vue du collecteur de routes de l’APNIC. L’essentiel de la table mondiale est identique partout, mais une route filtrée avant le collecteur n’y apparaît pas.

Questions fréquentes

Pourquoi mon /24 n'apparaît-il pas alors qu'un /16 si ?

Vos adresses sont annoncées dans le bloc plus large, et personne n'annonce le /24 séparément. C'est le cas normal pour la plupart des clients d'un opérateur.

Qu'est-ce qu'un détournement par préfixe plus spécifique ?

Quelqu'un annonce un préfixe plus long à l'intérieur de votre espace d'adresses. Les routeurs préférant la route la plus spécifique, le trafic va vers lui. RPKI avec une longueur maximale stricte rend ces annonces invalides.

Puis-je saisir une seule adresse ?

Oui. L'outil montre alors la route annoncée la plus spécifique qui la contient.
