IP Address:

255.255.255.255 32-bit address

The subnet mask 255.255.255.0 ip:198.162.0.1 indicates that the 198.162.0.0-198.162.0.255 host is the cell subnet that tells us which IP can access the range

255.255.255.0 binary 11111111 11111111 11111111 00000000

IP is divided into network address and host address, subnet mask 1 represents the network address occupied, 0 of the host address is overwritten.

Arbitrary network address and host address of cdir/1-32

The subnet mask is the dividing line between the network address and the host address.
