This is the documentation for libcorkipset 1.1.1+20150311-11, last updated Jan 24, 2021.
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.
