IPv4 to IPv6 Mapped Address Converter

Generate IPv6 transition addresses from any IPv4 host address.

Convert IPv4 into IPv6-mapped (::ffff:) and legacy IPv4-compatible (::) transition formats.

IPv4-mapped: ::ffff:c000:0201

IPv4-mapped (dotted): ::ffff:192.0.2.1

IPv4-compatible (legacy): ::c000:0201

Hex groups: c000:0201

32-bit binary: 11000000000000000000001000000001

32-bit hex: 0xC0000201

IPv4 to IPv6 Mapped Address Converter helps you generate ipv6 transition addresses from any ipv4 host address. It is commonly used by network admins, IT support teams, ops engineers for ipv4 to ipv6 mapped, ipv4-mapped ipv6, ipv4 compatible ipv6.

Maps each octet to hex and builds ::ffff: and :: legacy forms per RFC 4291.
