Network address — the base address of the block (10.0.36.128). All devices in this subnet share this prefix. Cannot be assigned to a host.

Broadcast address — packets sent to 10.0.36.159 are delivered to every device in the subnet. Also reserved — not assignable.

Usable hosts — the 30 addresses between those two that you can assign to servers, VMs, or interfaces.

Subnet mask255.255.255.224 is the dotted-decimal equivalent of /27. Older tools and Cisco configs use this format instead of CIDR slash notation.
