Why do I need to know my MAC address?

Par exemple, your router or network administrator might ask you for your MAC address in order to add your device to the network, or to troubleshoot connectivity issues. Some online services and applications may also require your MAC address in order to work properly.
Can I change my MAC address?
- Oui, you can change your MAC address, but this is not something that is typically recommended. Your MAC address is a unique identifier assigned to your network adapter by the manufacturer, and it is used for communication on the network. Changing your MAC address can cause problems with your network connectivity, and it may also be illegal in some countries.
Is my MAC address the same as my IP address?
- Non, your MAC address and your IP address are two different things. Your MAC address is a unique identifier assigned to your network adapter by the manufacturer, while your IP address is a numerical label assigned to your device by your network administrator or by your router. Your MAC address is used for communication on the local network, while your IP address is used for communication on the internet.
Can my MAC address be used to track me?
- Dans la plupart des cas, your MAC address cannot be used to track you. Your MAC address is a unique identifier assigned to your network adapter, and it is used for communication on the local network. It is not typically transmitted outside of your local network, so it cannot be used to track you on the internet. Cependant, it is possible for someone on your local network to use your MAC address to track your activities on that network.
Can my MAC address be changed by malware or hackers?
- Dans la plupart des cas, your MAC address cannot be changed by malware or hackers. Your MAC address is a unique identifier assigned to your network adapter by the manufacturer, and it is stored in the firmware of the network adapter. It is not typically possible for malware or hackers to change the MAC address, unless they have physical access to your device and are able to modify the firmware of the network adapter. Cependant, some malware and hackers may be able to spoof your MAC address, which means they can impersonate your MAC address in order to gain access to your network or your online accounts. This is why it is important to keep your device and your network secure, and to be cautious when connecting to unknown networks or downloading files from untrusted sources. If you suspect that your MAC address has been changed or spoofed by malware or hackers, you should immediately scan your device for malware and run a security check on your network. You may also need to contact your network administrator or your internet service provider for assistance.
