/32 at a glance
A /32 fixes the first 32 bits of the address as the network and leaves 0 bits for hosts, so it holds 2^0 = 1 address. There is nothing to subtract: the one address is the host.
A single address. Used for loopbacks, routed IPs on VMs, firewall rules for one host, and blackhole routes.
Most networks filter BGP announcements longer than /24, so a block this size cannot be routed on the internet on its own; it is carved out of a larger block by your provider.
