37.164.0.0/14
PublicClass A — /14 prefix — 262,142 usable hosts
Network address — the base address of the block (37.164.0.0). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 37.167.255.255 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 262,142 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 255.252.0.0 is the dotted-decimal equivalent of /14. Older tools and Cisco configs use this format instead of CIDR slash notation.
