75.2.18.0/24
PublicClass A — /24 prefix — 254 usable hosts
Network address — the base address of the block (75.2.18.0). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 75.2.18.255 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 254 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 255.255.255.0 is the dotted-decimal equivalent of /24. Older tools and Cisco configs use this format instead of CIDR slash notation.
