Appendix G: Powertech Exit Point Manager for IBM i and IPv6

Internet Protocol Version 6 (IPv6) is the next-generation protocol designed to replace IPv4. The primary difference between IPv6 and IPv4 is that IPv6 supports a greater number of IP addresses and is designed to meet the demand from Internet-capable devices in the future. Unlike IPv4, which uses 32-bit addressing, IPv6 addresses are 128-bits to handle the increased demand for IP addresses.

Powertech Exit Point Manager for IBM i 6.0 is IPv6-tolerant. That means that Powertech Exit Point Manager for IBM i can "tolerate" IPv6 addresses in every exit point managed by Powertech Exit Point Manager for IBM i 6.0.

Powertech Exit Point Manager for IBM i and IPv6 tolerance

A system can have both IPv6 and IPv4 address types active. However, when Powertech Exit Point Manager for IBM i detects an IPv6 client address, the IPv6 address will be "tolerated" by converting it to an IPv4 address. Whenever possible, the IPv4 address will be the address associated with the client.

If no IPv4 address can be determined, but a valid IPv6 address is supplied, Powertech Exit Point Manager for IBM i uses a default address (for example, 192.168.255.0). The default IP address is generated so you can make a decision on how to set rules.

If no valid address can be determined, Powertech Exit Point Manager for IBM i uses second default address (for example, 1.0.0.0).

NOTE: IPv6 "tolerance" differs from actual support of IPv6. Actual support of IPv6 will be included in a later release of Powertech Exit Point Manager for IBM i, as determined by need.
