BGP ASN Lookup With Python

Does anyone know of a Python module or a solution for how I could lookup company info (Name preferably) via the ASN (autonomous system number) number? There are lots of IP to ASN

Solution 1:

Try this, it's maybe what you need

from cymruwhois import Client
import ipresolved
domain='facebook.com'
ips=ipresolved.getipresolvedfromdomain(domain)
c=Client()
for i in ips.json()['resolutions']:
    ip=i['ip_address']
    print('ip : '+ip)
    r=c.lookup(ip)
    print('asn number: ',r.asn)
    print('asn owener : ',r.owner)
    print('==============')

Solution 2:

That information is available publicly on the CIDR-Report website.

This url has all the info you need and is updated daily. Big file, it might take a while to load : http://www.cidr-report.org/as2.0/autnums.html

Solution 3:

A slightly updated version of @Al-Pha answer:

Multi lookup:

from cymruwhois import Client
import socket

c = Client()
ip = socket.gethostbyname('globalresearch.ca')
for r in c.lookupmany([ip, "213.73.91.35"]):
    print(r.__dict__)
    # print(r.asn)

Single lookup:

c = Client()
r = c.lookup("213.73.91.35")
print(r.asn)
