Features Not Supporting Ipv6 - Avaya J169 Installing And Administering

If IPv4-only operation is enabled, the system ignores any IPv6 addresses configured as parameter
values and uses the next IPv4 address in the list. If the parameter value does not contain any IPv4
addresses, the system treats the value as null.
If IPv6-only operation is enabled, any IPv4 addresses configured as parameter values are ignored,
and the next IPv6 address (if any) in a list of addresses is used. If the parameter value does not
contain any IPv6 addresses, the system treats the value as null.
The results of the determination are expressed in the following table.

In general, if dual-stack operation is enabled, whether IPv4 or IPv6 is to be used to contact a
server is determined by the value of the parameter that contains the server address(es). However,
if the value is a DNS name and if DNS returns both an IPv4 and an IPv6 address, the one that will
be used is controlled by the parameter IPPREF.
