Network address — the base address of the block (237.252.89.152). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 237.252.89.155 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 2 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 255.255.255.252 is the dotted-decimal equivalent of /30. Older tools and Cisco configs use this format instead of CIDR slash notation.
