What IP address can cause duplication?
If you defined a static IP address for a network device, duplicate IP address conflicts may occur on a DHCP network. See more details. To resolve it, convert the network device with the static IP address to a DHCP client. Or, you can exclude the static IP address from the DHCP scope on the DHCP server.
What is duplicate IP detection?
Duplicate address detection (DAD) is used to verify that an IPv6 home address is unique on the LAN before the address is assigned to a physical interface (for example, QDIO). z/OS® Communications Server responds to other nodes that are doing DAD for IP addresses assigned to the interface.
