IP Calculator

Comprehensive IPv4 and IPv6 address calculator. For IPv4: compute subnet mask, wildcard mask, network address, broadcast address, first/last host, usable hosts, address class, and binary/hex representations from any CIDR notation. For IPv6: expand and compress addresses, determine address type (loopback, link-local, multicast, ULA, global unicast, etc.), detect IPv4-mapped addresses, and inspect all 8 groups with prefix network calculation.
