🔍 Key Concepts

• Private IP address ranges commonly used in home and small office networks • Typical default gateway (router) addresses at the start of a subnet • Difference between network address (.0) and host address (.1, .2, etc.)

💭 Think About

• Which IP range do you most often see on home Wi‑Fi networks when you check your device’s IP and gateway? Look for a familiar pattern like 192.168.x.x or 10.x.x.x. • Within a small home network, what address is usually given to the router: the very first usable host address (like .1) or a random one in the middle? • In a /24 network (255.255.255.0), which addresses are reserved for the network and broadcast, and which are valid for a router’s interface?

✅ Before You Answer

• Identify which options use the common 192.168.x.x private range that many home routers default to. • Check which addresses end in .0 (often a network address in small subnets) versus .1 (commonly used as the router/gateway). • Eliminate choices that contain numbers that are slightly off from the well‑known 192.168.x.x pattern.
