ipwhois is a Python package focused on retrieving and parsing whois data for IPv4 and IPv6 addresses.
The IPWhois argument allow_permutations and the lookup argument asn_alts have been deprecated in favor of new argument asn_methods.
NIR (National Internet Registry) lookups are enabled by default as of v0.14.0. This is currently only performed for JPNIC and KRNIC addresses. To disable, set inc_nir=False in your IPWhois.lookup_*() query.
The ‘nets’ -> ‘emails’ key in IPWhois.lookup_whois() was changed from a ‘\n’ separated string to a list in v0.14.0.
RDAP (IPWhois.lookup_rdap()) is the recommended query method as of v0.11.0. If you are upgrading from earlier than 0.11.0, please see the upgrade info.
If you are experiencing latency issues, it is likely related to rate limiting. Profiling the tests, I see most time spent attributed to network latency. Rate limiting is based on your source IP, which may be a problem with multiple users behind the same proxy. Additionally, LACNIC implements aggressive rate limiting. Bulk query optimization is on the roadmap (https://github.com/secynic/ipwhois/issues/134)

IPWhois (main class)¶
ipwhois.IPWhois is the base class for wrapping RDAP and Legacy Whois lookups. Instantiate this object, then call one of the lookup functions:
|address||String||An IPv4 or IPv6 address as a string, integer, IPv4Address, or IPv6Address.|
|timeout||Int||The default timeout for socket connections in seconds.|
|proxy_opener||Object||The urllib.request.OpenerDirector request for proxy support or None.|
|allow_permutations||Bool||Allow net.Net() to use additional methods if DNS lookups to Cymru fail. WARNING deprecated in favor of new argument asn_methods.|
IPWhois.lookup_rdap() is the recommended lookup method. RDAP provides a far better data structure than legacy whois and REST lookups (previous implementation). RDAP queries allow for parsing of contact information and details for users, organizations, and groups. RDAP also provides more detailed network information.
IPWhois.lookup() is deprecated as of v0.12.0 and will be removed. Legacy whois lookups were moved to IPWhois.lookup_whois().
Legacy Whois documentation:
National Internet Registries¶
This library now supports NIR lookups for JPNIC and KRNIC. Previously, Whois and RDAP data for Japan and South Korea was restricted. NIR lookups scrape these national registries directly for the data restricted from regional internet registries. NIR queries are enabled by default via the inc_nir argument in the IPWhois.lookup_*() functions.
Autonomous System Numbers¶
This library now supports ASN origin lookups via Whois and HTTP.
IP ASN functionality was moved to its own parser API (IPASN).
There is no CLI for these yet.
IP Reputation Support¶
This feature is under consideration. Take a look at TekDefense’s Automater:
There are no plans for domain whois support in this project.
Look at Sven Slootweg’s python-whois for a library with domain support.
