When creating or modifying a self-IP address, the system accepts the first or last address in a subnet as its address value.
The network address is reserved for identification of a network segment. The broadcast address is reserved by the system to address all nodes in a network at the same time.
This occurs when configuring self-IP addresses.
Do not assign the first or last address in a subnet to a self-IP address.
Added validation to ensure the first and last IP addresses in a subnet remain reserved, and cannot be assigned as self-IP addresses.
