libcorkipset-dev 1.1.1+20150311-7 (arm64 binary) in ubuntu bionic

 The ipset library provides C data types for storing sets of IP
 addresses, and maps of IP addresses to integers. It supports both
 IPv4 and IPv6 addresses. It's implemented using "Binary Decision
 Diagrams" (BDDs, https://en.wikipedia.org/wiki/Binary_decision_diagram),
 which (we hypothesize) makes it space efficient for large sets.
 .
 This package provides C header files for the library.
