Say you have a unsecured wireless network at school and I connect to it via NDS say I send a e-mail or something through that connection via NDS. Could the network admin know that it was a NDS that used the connection to do something or can they not tell it apart from a laptop? Basically does it have a mac address like a NIC does? Can they find out it came from a NDS or will they be clueless? Just to be clear I am not doing anything against the rules of the school or illegal I just always wondered this.
