201.97.64.128/25
PublicClass C — /25 prefix — 126 usable hosts
Network address — the base address of the block (201.97.64.128). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 201.97.64.255 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 126 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 255.255.255.128 is the dotted-decimal equivalent of /25. Older tools and Cisco configs use this format instead of CIDR slash notation.
