Your computer sends the request to your router, which then sends it out onto the Internet. At the hardware level of your network card, though, your network card is only looking at other MAC addresses for interfaces on the same network. Bear in mind that each network interface has its own MAC address.

So, on a typical laptop with both a Wi-Fi radio and a wired Ethernet port, the wireless and wired network interface each have their own unique MAC addresses. Most network cards allow you to set a custom MAC address from their configuration panes in the Device Manager, although some network drivers may not support this feature.
First, open the Device Manager. You can also do this the old-fashioned way. This involves taking the network interface down, running a command to change its MAC address, and then bringing it back up.
For that, you need the Terminal. As on Linux, this change is temporary and will be reset when you next reboot. You can verify your change took effect by running a command that shows your network connection details and checking what MAC address your network interface reports afterwards.

It tells you whether your computer can reach some destination IP address or domain name, and if it can, how long it takes data to travel there and back again. The command works by sending out multiple data packets and seeing how many of them return. Packet loss leads to poor performance in games and streaming, and this is a nifty way to test. By default it sends 4 packets, each one waiting 4 seconds before timing out.
You can increase the number of packets like this:. Like ping , it sends out a data packet as a way to troubleshoot any network issues you might have, but instead tracks the route of the packet as it hops from server to server. People talk about "surfing the web" and The command outputs a line-by-line summary of each hop, including the latency between you and that particular hop and the IP address of that hop plus domain name if available. Why do you see three latency readings per hop?

After sending out packets from you to a given destination, it analyzes the route taken and computes packet loss on a per-hop basis. Not only is it useful for the information it provides, but you can combine it with a couple switches to execute certain tasks.

Here are some of the more useful ones to start exploring right now. You may see more than one MAC address depending on how many network-related adapters are on your system.
For regular folks like you and me, its main use is finding out the IP address behind a certain domain name. This is normal for bigger websites because they spread their workload across many different machines. If you want to convert an IP address into a domain name, just type it into your browser and see where it leads.
But the command also has about a dozen switches that change what kind of information is displayed, such as the -r switch which shows a routing table instead. Running the netsh command on its own will shift the Command Prompt into network shell mode. But you can use it to run individual commands, too.
So for example, you can run this command to view all of the wireless network drivers on your system and their properties:. Then again, everyone should have at least a little bit of Command Prompt experience. It can come in handy when you least expect it.
