Descriptions

The various Is methods (IsPrivate, IsLoopback, etc) did not work as expected for IPv4-mapped IPv6 addresses, returning false for addresses which would return true in their traditional IPv4 forms.

Los diversos métodos Is (IsPrivate, IsLoopback, etc.) no funcionaron como se esperaba para las direcciones IPv6 asignadas a IPv4, devolviendo falso para direcciones que devolverían verdadero en sus formas IPv4 tradicionales.

A flaw was found in the Go language standard library net/netip. The method Is*() (IsPrivate(), IsPublic(), etc) doesn't behave properly when working with IPv6 mapped to IPv4 addresses. The unexpected behavior can lead to integrity and confidentiality issues, specifically when these methods are used to control access to resources or data.
