13.237.56.56/29
PublicClass A — /29 prefix — 6 usable hosts
Network address — the base address of the block (13.237.56.56). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 13.237.56.63 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 6 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 255.255.255.248 is the dotted-decimal equivalent of /29. Older tools and Cisco configs use this format instead of CIDR slash notation.
