| PackageDescription | very fast IP address to Autonomous System Number lookups
pyasn is a Python extension module that enables very fast IP address
to Autonomous System Number lookups. Current state and Historical
lookups can be done, based on the MRT/RIB BGP archive used as input.
.
pyasn is different from other ASN lookup tools in that it provides
offline and historical lookups. It provides utility scripts for users
to build their own lookup databases based on any MRT/RIB
archive. This makes pyasn much faster than online dig/whois/json
lookups.
.
The module is written in C and Python, and cross-compiles on Linux and
Windows. Underneath, it uses a radix tree data structure for storage
of IP addresses. In the current version, it borrows code from
py-radix to support both IPV4 and IPV6 network prefixes. The current
release is a beta. Compared to the previous version, it provides
support for Python 2 and 3; adds new functionality, performance
improvements, and unit-tests.
.
pyasn is developed and maintained by researchers at the Economics of
Cybersecurity research group at Delft University of Technology
(http://econsec.tbm.tudlft.nl). The package is used on an almost
daily basis and bugs are fixed pretty quickly. The package is largely
developed and maintained by Hadi Asghari and Arman Noroozian. Please
report any bugs via GitHub (https://github.com/hadiasghari/pyasn) or
email the developers. |
