200.232.248.0/21
PublicClass C — /21 prefix — 2,046 usable hosts
Network address — the base address of the block (200.232.248.0). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 200.232.255.255 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 2,046 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 255.255.248.0 is the dotted-decimal equivalent of /21. Older tools and Cisco configs use this format instead of CIDR slash notation.
