Errrrrm....as I understand it, every peice of equipment connected to your pc, that you use to connect to the web with, has an individual mac address (16 character unique identifier). If you connect through a router, nic card etc, the mac address is made available to the isp you connect to - so in theory you would not have to create alarms on any monitoring solution you have. Then again, I may well be wrong.....lol.....that wouldnt be too unusual for me.....only been doing this 7 years or so.......
