How IPv4 to IPv6 mapping works
An IPv4 address contains 32 bits. IPv6 uses 128 bits, so applications need a standard way to represent IPv4 addresses in an IPv6 context.
The mapped form starts with ::ffff:, followed by the IPv4 address encoded as two hexadecimal groups.
Enter an IPv4 address above to create a direct, shareable conversion URL with the exact mapped IPv6 result.
When an IPv4-mapped address is useful
Use this converter when an IPv6-aware application, proxy, operating system, or log shows an IPv4 client in IPv6 notation. It is especially useful when troubleshooting dual-stack sockets, access-control rules, application logs, container networking, and reverse-proxy headers.
An IPv4-mapped value is a software representation. It does not assign a native IPv6 address, create a route, or make an IPv4-only service reachable over IPv6. Translation systems such as NAT64 need their own configured prefix and gateway.
