Summary

ipwhois is a Python package focused on retrieving and parsing whois data for IPv4 and IPv6 addresses.

Note

If you are experiencing latency issues, it is likely related to rate limiting. 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. Experimental bulk query support is new as of v1.0.0.

Features

  • Parses a majority of whois fields in to a standard dictionary
  • IPv4 and IPv6 support
  • Supports RDAP queries (recommended method, see: https://tools.ietf.org/html/rfc7483)
  • Proxy support for RDAP queries
  • Supports legacy whois protocol queries
  • Referral whois support for legacy whois protocol
  • Recursive network parsing for IPs with parent/children networks listed
  • National Internet Registry support for JPNIC and KRNIC
  • Supports IP to ASN and ASN origin queries
  • Python 2.6+ and 3.3+ supported
  • Useful set of utilities
  • Experimental bulk query support
  • BSD license
  • 100% core code coverage (See '# pragma: no cover' for exclusions)
  • Human readable field translations
  • Full CLI for IPWhois with optional ANSI colored console output.

API

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:

RDAP (HTTP) - IPWhois.lookup_rdap() OR Legacy Whois - IPWhois.lookup_whois()

Input

Key Type Description
address str An IPv4 or IPv6 address as a string, integer, IPv4Address, or IPv6Address.
timeout int The default timeout for socket connections in seconds. Defaults to 5.
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. Defaults to True.

RDAP (HTTP)

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.

Legacy Whois

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.

https://ipwhois.readthedocs.io/en/latest/NIR.html

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.

Experimental Functions

Caution!

Functions in experimental.py contain new functionality that has not yet been widely tested. Bulk lookup support contained here can result in significant system/network resource utilization. Additionally, abuse of this functionality may get you banned by the various services queried by this library. Use at your own discretion.

IP Reputation Support

This feature is under consideration. Take a look at TekDefense's Automater:

Domain Support

There are no plans for domain whois support in this project.

Look at Sven Slootweg's python-whois for a library with domain support.

Special Thanks

Thank you JetBrains for the PyCharm open source support!

Thank you Chris Wells (@cdubz) for your extensive testing on the experimental functions!

Last but not least, thank you to all the issue submitters and contributors.
