A practical guide to representing IPv4 addresses in IPv6-compatible formats using Java. Covers four approaches: IPv4-mapped IPv6 addresses (::ffff: prefix), deprecated IPv4-compatible addresses (:: prefix), NAT64-style translation (64:ff9b:: prefix), and 6to4 tunneling (2002::/16 prefix with hex-encoded IPv4 bytes). Includes Java code snippets for each method and a JUnit test example. Clarifies that these are embedding/transition techniques, not true protocol conversions.
