102.159.42.160/27
PublicClass A — /27 prefix — 30 usable hosts
Network address — the base address of the block (102.159.42.160). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 102.159.42.191 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.
