174.52.0.0/17
PublicClass B — /17 prefix — 32,766 usable hosts
Network address — the base address of the block (174.52.0.0). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 174.52.127.255 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 32,766 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 255.255.128.0 is the dotted-decimal equivalent of /17. Older tools and Cisco configs use this format instead of CIDR slash notation.
