Configure support for IPv6 addressing on a computer running an IBM
® i operating system.
Before you begin
You must be using IBM
i V6R1 with Sametime if you want to support IPv6 addressing; if you are using an older version of i5/OS
®, upgrade to V6R1 before configuring the operating system to support IPv6 as described below. To see the complete list of IBM
i and i5/OS
versions supported by Sametime, see the system requirements for this release at the following web addresses:
Sametime 8.5.2 Interim Feature Release 1 (Sametime 8.5.2 must be installed first)
For information on the IBM
i operating system, visit the IBM System i information center
About this task
These instructions describe how to enable support for IPv6 addressing on a functioning Sametime
® server that is currently using IPv4 addressing.
Follow the steps below to update the IBM
i TCP/IP configuration for the IPv6 address you will use for your Sametime server:
Some of the components of a Sametime server require the use of an IPv4-formatted loopback address. To ensure that your Sametime server functions properly, do not disable IPv4 support in your server operating system – instead, enable support for both IPv4 and IPv6 addressing.
Parent topic: Enabling IPv6 on a server operating system
- Add the IPv6–formatted IP address that you will use for your Sametime server.
- Add an entry in the local host table for the IPv6 IP address.
- Update the Domain Name Server.
The contents of the Domain Name Server should be similar to the local host table, with two DNS entries for the host name of your Sametime
server: one entry that maps the host name to the IPv4 address and another that maps it to the IPv6 address.
See Updating the Domain Name Server for IBM i sta852ifr1
for special considerations when TCP/IP is configured to check the DNS before the local host table.
