Question
**Challenge: Network Subnet Mask Identification** Assume that the assigned network addresses are correct. Can you deduce (guess) what the network subnet mask is? Explain your reasoning. *Hint: Look at the addresses in binary and consider the host IDs.* --- In this challenge, you're tasked with determining the network subnet mask based on given network addresses. This involves analyzing the binary representation of the addresses and identifying which parts represent the network and host IDs. Understanding the distribution of these bits will allow you to infer the subnet mask.

The image illustrates a network infrastructure involving two hosts, two routers, a bridge, and various connections with associated IP and MAC addresses. **Components and Connections:** 1. **Host A** - IP Address: 198.12.56.40 - MAC Address: 6611 - Connected to Router-1 via a wire with the address: 198.12.56.32 2. **Router-1** - Port (Ethernet 0 = E0) - MAC Address: 3232 - IP Address: 198.12.56.33 - Port (E1) - MAC Address: 3456 - IP Address: 198.12.56.65 - Connected via a wire with the address: 198.12.56.64 - Port (E2) - MAC Address: 2244 - IP Address: 198.12.56.97 3. **Router-2** - Port (E1) - MAC Address: 7755 - IP Address: 198.12.56.98 - Connected via a wire with the address: 198.12.56.96 - Port (E0) - MAC Address: 8787 - IP Address: 198.12.56.129 - Connected to the bridge 4. **Bridge** - Port 0 MAC Address: 8899 - Port 1 MAC Address: 6789 - Connects to Router-2 (E0) and Host B via a wire with the address: 198.12.56.128 5. **Host B** - MAC Address: 1234 - IP Address: 198.12.56.140 - Connected through the bridge to Router-2 **Network Explanation:** - Host A is directly connected to Router-1, which has three ports (E0, E1, E2) each with distinct IP and MAC addresses, managing different connections. - Router-2 connects to Router-1 via port E1 and to a bridge using port E0. The bridge facilitates communication between Router-2 and Host B. - Each connection between routers and hosts is defined by specific wire addresses, ensuring organized traffic flow within the network.
