Coding

Searching by IP address

import ip2asn
i2a = ip2asn.IP2ASN("ip2asn-v4-u32.tsv")
result = i2a.lookup_address("93.184.216.34")

import pprint
pprint.pprint(result)

Produces:

{'ASN': '15133',
 'country': 'US',
 'ip_numeric': 1572395042,
 'ip_range': [1572394752, 1572396543],
 'ip_text': '93.184.216.34',
 'owner': 'EDGECAST - MCI Communications Services, Inc. d/b/a Verizon Business'}

Searching by ASN

import ip2asn
i2a = ip2asn.IP2ASN("ip2asn-v4-u32.tsv")
results = i2a.lookup_asn(15169, limit=2)  # limit is optional

import pprint
pprint.pprint(results)
``**

**Produces:**

  'country': 'US',
  'ip_range': [134743040, 134743295],
  'owner': 'GOOGLE - Google LLC'},
 {'ASN': '15169',
