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 Communications 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.
