OK, so i have an 802.11G Wireless setup at home, and for some reason my Belkin Router seems to think my Macbook has two MAC Addresses and assigns it two I.P. addresses too. This doesn't cause me any issues, other than when i want to set up port forwarding in Torrent clients such as Vuze or Transmission i never know which IP address to use. How is this even possible? None of my other Mac's do it, so its not a problem with my router, which piece of Wireless networking hardware in the 17" Unibody Macbook Pro could have two distinct MAC Addresses, i didn't think that was even possible.
