python-ipaddr 2.1.11-2 (armhf binary) in ubuntu bionic

 This library is used to create/poke/manipulate IPv4 and IPv6 addresses
 and networks in Python. It is intended to be fast and lightweight.
 .
 This is a pure Python implementation of classes for IPv4/6 addresses and
 networks. It supports comparisons to determine if IP addresses are contained
 inside a defined network, conversion of lists of IP addresses into compact
 CIDR lists, and other IP address manipulation.
