219.252.144.0/23
PublicClass C — /23 prefix — 510 usable hosts
Network address — the base address of the block (219.252.144.0). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 219.252.145.255 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 510 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 255.255.254.0 is the dotted-decimal equivalent of /23. Older tools and Cisco configs use this format instead of CIDR slash notation.
