222.168.175.208/28
PublicClass C — /28 prefix — 14 usable hosts
Network address — the base address of the block (222.168.175.208). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 222.168.175.223 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 14 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 255.255.255.240 is the dotted-decimal equivalent of /28. Older tools and Cisco configs use this format instead of CIDR slash notation.
