Remember, you're likely not as anonymous as you think you are online.

If you don't want people to be able to track you then don't post stuff on the Internet. There's all kinds of information that you wouldn't even think about; check out the Panopticlick project to see some of the uniquely identifiable information that your web browser is giving away that you probably never thought of.

Even if you go all secret squirrel and randomly hop between Internet cafes and public libraries, you can still be uniquely identified by things like the structure of your social graph.

You'll just have to take comfort in the fact that you are not important enough for a smart person to care about stalking you. Just make sure to clear your browser cookies after watching porn so that your wife doesn't kick your ass and call it good.





How would someone outside of your LAN see your MAC address?

all that's really gonna do is hide you, somewhat, within your subnet.
but you're not invisible to your network admin.
you're gonna be one of 254 physical addresses on your LAN if I'm correct.

Unless the network admin actually keeps track of which MAC address goes to which to user then all anyone knows is who made your network adapter, and if the admin knows enough to keep track of that he can probably just walk by your office to see if you're using your computer or not. There are reasons to alter MAC addresses but anonymity isn't really one of them.

Your MAC address is your physical address. The number of possible network addresses all depends on how your network is set up, but home routers default to something like 192.168.1.0/24 which would be 254 possible addresses.

Random web sites can easily know who you are, your email address and company, among other things.
