Palo Alto Networks Cybersecurity-Apprentice Exam - Topic 5 Question 12 Discussion

IP subnetting divides a larger IP network into smaller logical networks by changing the subnet mask or prefix length. Because each subnet has a defined address range, subnetting directly limits how many usable host addresses are available inside that segment. For example, a smaller subnet provides fewer assignable private IP addresses, which restricts the number of devices that can be placed in that network. NAT translates addresses between networks, but it does not itself define the size of the internal address pool. Static routing controls forwarding paths and does not limit how many devices can receive private IP addresses. VLANs segment Layer 2 broadcast domains, but the host count is ultimately determined by the IP subnet assigned to that VLAN. In secure network design, subnetting is often paired with VLANs and zones so that addressing, routing, and policy enforcement align cleanly.
