IPv6 / IPv4 Translations

The ingress or egress traffic type, whether IPv4 or IPv6, must match the configuration of the realm where attached, as in-realm-id or out-realm-id. A realm and IP version configuration mismatch results in an error message and log entry at error level.

IPv6 to IPv4 flows exit the Oracle® Enterprise Session Border Controller with the prefix ::fff:0:0:0/96. They may be written as ::ffff:0:a.b.c.d, where a.b.c.d refers to an IPv6-enabled node.

While IPv4 addresses can be translated into IPv6 addresses, IPv6 address can not be translated to IPv4.
