[ QUICK GUIDE ]

Network address: identifies the subnet.

Broadcast address: addresses all hosts on a traditional IPv4 subnet.

Subnet mask: identifies the network bits in the address.

CIDR prefix: the number of network bits. For example, /24 means 24 network bits.

/31: commonly used for point-to-point links; both addresses are usable as endpoints.

/32: represents one IPv4 address, commonly used as a host route.
