summary: 'CIDR math: IPv4 and IPv6 overlap, adjacency, merge, subtract, membership'
description: 'Computes exact CIDR relations for agents planning networks, firewall rules or allow-lists: for up to 200 IPv4/IPv6 blocks it reports which pairs are equal, nested, partially overlapping or merely adjacent, the minimal merged CIDR list, a subtraction (blocks minus exclusions), address membership with the most specific match, or each block''s first/last address, count and host-bits-set errors. It does not resolve hostnames, look up ownership or routing, interpret IPv6 zone ids, or decide whether an overlap is intentional; IPv4-mapped IPv6 stays a separate family unless normalizeMapped is true.
