When a device connects, it always receives a specific IP address if it has a matching MAC address Static IP Assignment: Routers allow you to assign static IP addresses to your computers.
In addition to their core networking use, MAC addresses are often used for other purposes: RELATED: 22 Common Network Jargon Terms Explained It knows to send the request to the MAC address of your router’s network interface. 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. Your computer sends the request to your router, which then sends it out onto the Internet. The web address you type gets translated to the IP address of the server. When a browser on your computer needs to grab a web page from a server on the Internet, for example, that request passes down through several layers of the TCP/IP protocol. What MAC Addresses Are Used ForĪt the lowest networking level, network interfaces attached to a network use MAC addresses to communicate with one another. These MAC addresses-sometimes referred to as physical or hardware addresses-are assigned in the factory, but you can usually change the addresses in software.

Better to be conservative like Android and avoid inciting the newbs.Each network interface connected to your network-whether it’s your router, wireless device, or network card in your computer-has a unique media access control (MAC) address. So, you can say "it should be a default" all you like, but everyone's going to have a different idea of what the default is for and they're going to throw a fit about it not being "the right default". If one is looking to avoid having to pay for overstaying their visit at a coffee house or similar capture portal, maybe what needs to be changed is one's sense of ethics, and changing a MAC won't help with that. If you're looking to avoid tracking by people doing traffic analysis to correlate by behaviour no amount of MAC trickery will help you.
If you're looking to keep an open Wifi provider from tracking you over the course of days, then using a different MAC for each connect is going to be sufficient. If your only concern is passive tracking, then a randomized MAC being used for SSID probes (because whitelist-only hidden SSIDs are rare enough that those people can manually connect) will be sufficient. What makes it easier is having fixed goals in mind, because I am seeing a lot of people in this thread arguing because they're all solving different problems which is obviously going to mean different solutions. Your threat model is different - maybe APT-level - and you have to do way more than changing your mac address.

But I agree that this is just 1-3 lines of code for realistic mac address generation so it should be unproblematic to add.Įdit: If you have fears of being uncovered by random-looking mac addresses without vendor prefixes, changing your mac address will probably not help you. And even then you can see the VPN server IP in the logs so you should also make precautions and buy your VPN connection anonymously (and even then - you'll never know if you're really anonymous).Ĭhanging your mac address seems to be sufficient (in addition to the VPN usage) to prevent easy tracking through something unique like your real mac address. In this case it doesn't matter that you've randomized your mac address in a way which can be clearly identified as random. The DNS requests you'll make will reveal which sites you frequent. I think it's not a good idea to change your mac address as your only precaution against tracking.
