Given a list of IPs the tool returns their AS numbers and names.
Data sources:
Features:
- Caching the data from sources - first run may take a long time,
- Binary IP network search for high throughput,
- Returns AS Number, AS Name and a country code for each IP address.
- Supports both IPv4 and IPv6
- Also available as a lib!
pip install asn-check
--input-file FILENAME Input file with one IPv4 per line [default:STDIN]

--log-level [DEBUG|INFO|WARNING|ERROR|CRITICAL] Set logging level. [default: WARNING]
--help Show this message and exit.

Note: If you'd like to use your own data sources, theoretically you can, but they need to follow the same format as the APNIC sources (and the format is not consistent!) - check out the constructor options asn_routes_url_v4, asn_routes_url_v6, asn_names_url. I'd recommend sticking to the defaults.
