01 - find-asn - Part 1

Ci-dessous quelques exemples qui peuvent être facilement utilisés pour identifier une liste de ASN associé à une organisation.

Exemple avec le Gouvernement du Canada via le site BGP.he.net :

Sur le site https://bgp.he.net/ entrée dans le champs de recherche :

shared services canada

Lien direct incluant la recherche : https://bgp.he.net/search?search%5Bsearch%5D=%22shared+services+canada%22&commit=Search

screenshot

Bien que le résultats contient une bonne quantité de ASN, il ne couvre pas entièrement le Gourvernement du Canada. Certains ASN du gouvernement du Canada ne sont pas au nom de "shared services canada".

Un Exemple pourrait être AS27293 qui est associé à la banque du canada du Gouvernement du Canada.

Lien : https://bgpview.io/asn/27293#prefixes-v4

bankofcanada

Un dernier exemple, AS3848 est associé à worldlinx-2, mais il contient un subnet dédié à l’utilisation de Poste Canada.

Lien : https://bgpview.io/prefix/198.33.104.0/21

postcanada

Exemple avec Desjardins via l’API de bgpview.io avec une recherche par mot clé “desjardins” :

Vous pouvez utiliser la commande jq pour afficher le résultat ou encore enregistrer dans un fichier avec l'option -o de curl

curl -sS https://api.bgpview.io/search?query_term=desjardins | jq '.'
