160.0.0.0/5
PublicClass B — /5 prefix — 134,217,726 usable hosts
Network address — the base address of the block (160.0.0.0). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 167.255.255.255 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 134,217,726 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 248.0.0.0 is the dotted-decimal equivalent of /5. Older tools and Cisco configs use this format instead of CIDR slash notation.
