ASN Info

A python library providing information about ASNs (AS Name, Country and MANRS membership)

This library downloads the Autonomous System list and information from RIPE NCC and provides its contents as objects.

There are three data points:

• Autonomous System Name: get_as_name()
• Autonomous System Country: get_as_country()
• Wether an ASN is a MANRS Participant: is_manrs_participant()

MANRS Data is not loaded by default, since it requires an API key. In case you want to load it, you will have to prepare a .env file containing a line like this:

MANRS_API_KEY=ad83444d-4c68-4727-9ff6-ce2df6649c05

You can obtain an API key here

Example use:

import asn_info

asn_data = asn_info.Asns()

h = asn_data.load_asn_data(add_manrs_data=True)

print(asn_data.get_as_name(58280))
print(asn_data.get_as_country(58280))
print(asn_data.is_manrs_participant(58280))

Result:

STUCCHIMAX-AS Massimiliano Andrea Stucchi
CH
False

You can also filter the ASNs per country, as follows:

switzerland = asn_data.asns_per_country("CH")

for asn in switzerland:
    print("{} has {}".format(asn, switzerland[asn]))

Output:

...
58280 has {'country': 'CH', 'as_name': 'STUCCHIMAX-AS Massimiliano Andrea Stucchi'}
...
