Why each option
Private IPv4 addressing is appropriate for a new subnet when unique public address space is limited, and traffic on the subnet is primarily local to the organization's network.
Private IP addresses are ideal for internal network segments where devices do not need direct public internet accessibility, preserving public IP addresses and allowing flexible internal numbering without global conflicts, especially when subnet traffic remains local.
While limiting broadcasts is a good network design principle, private addressing itself does not directly limit broadcasts; proper subnetting and network segmentation achieve this.
