Network address — the base address of the block (176.0.0.0). All devices in this subnet share this prefix. Cannot be assigned to a host.

Broadcast address — packets sent to 191.255.255.255 are delivered to every device in the subnet. Also reserved — not assignable.

Usable hosts — the 268,435,454 addresses between those two that you can assign to servers, VMs, or interfaces.

Subnet mask — 240.0.0.0 is the dotted-decimal equivalent of /4. Older tools and Cisco configs use this format instead of CIDR slash notation.
