About IPv4 & IPv6 Address Validator

The IPv4 & IPv6 Address Validator and Range Inspector analyzes IP addresses, verifying structural RFC syntax, identifying address versions (IPv4 vs IPv6), classification types (Public, Private RFC 1918, Loopback, Link-Local, Multicast), and binary / hexadecimal bit representations.

Technical Glossary

Key Terminology & Definitions

RFC 1918 Private Addressing

Reserved IPv4 blocks (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) designated for private local area networks.

IPv6 Zero Compression (`::`)

A syntax rule allowing one contiguous sequence of 16-bit zero fields to be replaced with double colons `::`.
