176.205.100.176/28
PublicClass B — /28 prefix — 14 usable hosts
Network address — the base address of the block (176.205.100.176). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 176.205.100.191 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.
