Network address — the base address of the block (10.0.1.0). All devices in this subnet share this prefix. Cannot be assigned to a host.

Broadcast address — packets sent to 10.0.1.63 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 mask255.255.255.192 is the dotted-decimal equivalent of /26. Older tools and Cisco configs use this format instead of CIDR slash notation.

The first 26 bits (1s in the mask) identify the network. The remaining 6 bits identify hosts within the network.

Subnet Breakdown — splitting into /27

This /26 block can be divided into 2 /27 subnets.
