To find your Chromebook's IPv4 address and MAC address (hardware address), click the time in the bottom right, select "Settings," then click the network icon and the network you're connected to, and finally, click "Information" to view your IP address.
Here's a more detailed breakdown:
Access Settings: Click the time in the bottom right corner of your screen, then select "Settings" (the gear icon).
Navigate to Network: Click on the "Network" section.
Select Connected Network: Find and click on the Wi-Fi network you're currently connected to.
View Information: Click the "Information" button (or the "i" icon) to view network details.
Locate IP Address and MAC address: Your IPv4 address and MAC address will be listed under the IP Address section.
Traceroute is a network diagnostic tool used to trace the path packets take across an IP network from a source to a destination, displaying the IP addresses and response times of each router along the route.
Purpose: Traceroute helps identify potential network issues, such as slow connections, packet loss, or routing problems.
How it works: It sends a series of Internet Control Message Protocol (ICMP) echo requests to the target, with incrementally increasing Time-To-Live (TTL) values.
TTL: Each router along the path decrements the TTL value. When the TTL reaches zero, the router sends an ICMP Time Exceeded message back to the source, revealing the router's IP address.
Windows: In Windows, the tool is known as "tracert".
Unix-like systems: On Unix-like systems (including macOS), it's called "traceroute".
Command: To use traceroute, you typically open a command prompt or terminal and type traceroute (or tracert on Windows) followed by the destination domain name or IP address.
Example: traceroute google.com or tracert google.com
Output: The output shows the hops (routers) between the source and destination, along with the time taken for each hop.
Troubleshooting: Traceroute can help pinpoint where network delays or problems are occurring.
Other Uses: It can also be used to gather information about network infrastructure and IP address ranges.
On a Chromebook, you access a command-line environment, similar to a terminal, by pressing Ctrl+Alt+T to open the crosh shell, and then typing "shell" to access the underlying Linux shell.
To rotate the screen on a Chromebook, use the keyboard shortcut Ctrl + Shift + Refresh (the refresh key is the one with the arrow moving in a circle). Each press rotates the screen 90 degrees.
