BulkWhois 0.2.1

BulkWhois provides a simple interface to several bulk whois servers. This allows you to look up the ASNs, AS names, country codes, and other assorted information very efficiently for a large number of IP addresses.

Currently implemented bulk whois servers are:

Cymru: BulkWhoisCymru Shadowserver: BulkWhoisShadowserver

Note that these whois servers generally only accept IPv4 IP addresses, not hostnames. IPv6 support is not widely supported by bulk whois servers at present, but will add in support once this becomes available.

So, it’s up to the caller to convert hostnames to IP addresses first. Anything which isn’t an IPv4 address generates a warning and is dropped before sending to the whois server.

Usage:

#!/usr/bin/env python

from bulkwhois.shadowserver import BulkWhoisShadowserver

bulk_whois = BulkWhoisShadowserver()
records = bulk_whois.lookup_ips(["212.58.246.91", "203.2.218.214"])

for record in records:
    print "\t".join([records[record]["ip"], records[record]["asn"],
                    records[record]["as_name"], records[record]["cc"]])
