A second place you can see the physical and interface addresses on Windows 11 is through the Control Panel. Once you have opened the Control Panel, select Network & Internet, then View Network Status and Tasks. Following this process opens a screen with the label View your basic network information and set up connections at…

To find and verify the network configuration in Windows 11 using the graphical user interface (GUI), open the Settings app and the Network & Internet section. A host may have several interfaces; you must select an individual interface to find its addresses and other information. Figure 4-1 illustrates the Network & internet section for a…

This chapter covers the following exam topics: 3. Endpoints and Media Types 3.4. Demonstrate how to set up and check network connectivity on Windows, Linux, Mac, Android, and Apple mobile OS. Networking utilities on Windows, Linux, Android, and Apple operating systems; how to run troubleshooting commands; wireless client settings (SSID, authentication, WPA mode) 5. Diagnosing…

What if you have a network like the one illustrated in Figure 3-15? If host A has its default gateway set to router B, it does not seem as though it can ever send any packets to E.Figure 3-15 Redirects Router B is configured as host A’s default gateway. When A sends a packet toward…

It is possible, from time to time, for a routing loop to form in a network. Figure 3-13 illustrates. Figure 3-13 A Routing Loop If host A sends a packet toward F, then 1.  Router B forwards the packet to D. 2.  Router D forwards the packet to E. 3.  Router E forwards the packet…

Routers and switches are opaque boxes to most network operators and engineers. To better understand how these devices forward packets, and the relationship between the physical interfaces, the routing table, and the applications (like routing protocols), it is useful to peek inside. Figure 3-12 illustrates. Figure 3-12 Router Components Figure 3-12 is a simplified version…

Routers build routing tables from a variety of sources, but the primary ones are • Including the IP address of each connected interface • Manual configuration, or static routes • Dynamic routing protocols Including the connected interfaces is obvious: the router knows about these networks because it has direct local configuration information. Static routes are…
