SYS_CONTEXT('USERENV','IP_ADDRESS') Doesn'T Return Ipv4 Address When Ipv6 is Enabled (Doc ID 1175504.1)

Last updated on OCTOBER 24, 2016

Applies to:

Oracle Server - Enterprise Edition - Version: 11.1.0.7 and later   [Release: 11.1 and later ]
Information in this document applies to any platform.

Symptoms

Using the 11.1.0.7 listener

select sys_context('USERENV','IP_ADDRESS') from dual;

returns the correct IPv4 Address
Eg: 10.16.120.165.
With the 11.2.0.1 listener the result is "::ffff:10.16.120.165".
The listener.ora files are identical for the 11.1 and 11.2 listeners.


Changes

This happens when using a 11.2.0.1.0 instead of the listener 11.1.0.7.0 with a 11.1.0.7.0 database.
