178.4.189.160/27
PublicClass B — /27 prefix — 30 usable hosts
Network address — the base address of the block (178.4.189.160). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 178.4.189.191 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 30 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 255.255.255.224 is the dotted-decimal equivalent of /27. Older tools and Cisco configs use this format instead of CIDR slash notation.
