IPv4-mapped IPv6 address for 18.233.41.13

IPv4 input

18.233.41.13

IPv6 mapped output

::ffff:12e9:290d

Expanded IPv6 address

0000:0000:0000:0000:0000:ffff:12e9:290d

IPv4 dotted-quad notation

::ffff:18.233.41.13

::ffff:12e9:290d is the IPv4-mapped IPv6 representation of 18.233.41.13. It embeds the 32-bit IPv4 value after the ::ffff: prefix.

IPv4-mapped addresses are commonly used by dual-stack software to represent IPv4 peers in an IPv6-aware API. They do not turn an IPv4-only host into a natively routed IPv6 host.

The compact hexadecimal, expanded, and dotted-quad forms above represent the same 128-bit IPv6 value. Dotted-quad notation makes the embedded IPv4 address easier to recognize in logs and diagnostics.

Learn how IPv4-mapped IPv6 addresses work and how mapping differs from IPv4-to-IPv6 translation.
