Network address — the base address of the block (11.59.224.0). All devices in this subnet share this prefix. Cannot be assigned to a host.

Broadcast address — packets sent to 11.59.255.255 are delivered to every device in the subnet. Also reserved — not assignable.

Usable hosts — the 8,190 addresses between those two that you can assign to servers, VMs, or interfaces.

Subnet mask — 255.255.224.0 is the dotted-decimal equivalent of /19. Older tools and Cisco configs use this format instead of CIDR slash notation.
