Network address — the base address of the block (65.9.48.0). All devices in this subnet share this prefix. Cannot be assigned to a host.

Usable hosts — the 1,022 addresses between those two that you can assign to servers, VMs, or interfaces.

Subnet mask255.255.252.0 is the dotted-decimal equivalent of /22. Older tools and Cisco configs use this format instead of CIDR slash notation.
