1.98.127.96/28
PublicClass A — /28 prefix — 14 usable hosts
Network address — the base address of the block (1.98.127.96). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 1.98.127.111 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.
