Using MAC Address to Uniquely Identify Computers
An anonymous reader writes "One of Australia's gaming networks, GamesArena has recently imposed a third party program required to access their gaming servers. One of it's features is that it records your NIC's MAC address to identify your computer, and subsequently in future, ban you if you cheat/break the rules etc. The response from players is mixed. It is not open source software, nor is it optional to install. "Install it or find another server to play on". Question remains, is it going too far?"
Definitely not- unfortunately it won't work since MACs are changable.
It's in quotes because it implies that the reader has a moderate intelligence and can use the term "routing" literally (meaning "finding the most direct path". I find a "route" to work, but that doesn't mean I run TCP/IP), rather than "in my MCSE course" (which I _knew_ some moron, yourself being a perfect example, which come swaggering in proclaiming). If you have an interconnected network of layer 2 ethernet switches, the path between any two users, regardless of the number of points in between, will "route" based upon the MAC addresses that each switch has assigned to each port. A network of interconnected ethernet switches is no different than an interconnected network of layer 3 or higher devices.
You might want to take a look at those crazy modern switches we have these days: There is a world beyond hubs you know.
