Two are selected from the available IP addresses in
Server Segment. (※)

one IP Address and a standby device uses one IP Address.

interface only when the Server Segment is created based on the
application form.
If IP addresses have not been specified, they will be allocated
automatically.
 You cannot change the IP addresses that are allocated to the Server
Segment-side network interface.
