159.200.0.0/13
PublicClass B — /13 prefix — 524,286 usable hosts
Network address — the base address of the block (159.200.0.0). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 159.207.255.255 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 524,286 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 255.248.0.0 is the dotted-decimal equivalent of /13. Older tools and Cisco configs use this format instead of CIDR slash notation.
