219.237.81.64/26
PublicClass C — /26 prefix — 62 usable hosts
Network address — the base address of the block (219.237.81.64). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 219.237.81.127 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 62 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 255.255.255.192 is the dotted-decimal equivalent of /26. Older tools and Cisco configs use this format instead of CIDR slash notation.
