It lists CIDR values from /32 down to /0 with masks and wildcard equivalents, enabling quick subnet planning and range calculation. Additional sections cover decimal-to-binary mask components, IP address classes (A–E), reserved private ranges and special networks like localhost and Zeroconf, and key terminology for CIDR and
