100.97.252.0/22
PublicClass A — /22 prefix — 1,022 usable hosts
Network address — the base address of the block (100.97.252.0). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 100.97.255.255 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 1,022 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 255.255.252.0 is the dotted-decimal equivalent of /22. Older tools and Cisco configs use this format instead of CIDR slash notation.
