Network address — the base address of the block (0.2.90.176). All devices in this subnet share this prefix. Cannot be assigned to a host.

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.
