IPv4 dotted-quad notation
::ffff:131.216.14.76
::ffff:83d8:e4c is the IPv4-mapped IPv6 representation of 131.216.14.76. 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.
