1. Whether or not you have “Locally Administered Address” in the property panel of your NIC is dependent on a registry entry. It is possible to add this for any NIC. I had this issue with one WiFi card, and exported the registry entries from a different card, and hand edited it in for the card that was lacking them in the registry. All NICs can have their address changed; most had DOS utils back in the day for doing this.

2. Any valid Hex number (00-FF) will work in each slot, but it’s possible that the AP or DHCP server could refuse to connect.

3. “F0C0FFF0C0FF” will work, unless the AP/DHCP server is somehow set as described above.

4. I used this method all the time when parking my semi at truck stops that offered (pay) WiFi. Works in airports and any place using only mac addresses for authorization.

This is dependant on the NIC Drivers, not all drivers will have the same set of advanced options and the naming can be different.

There is another method that is NIC independent, Method 2 at the link bellow

@Bob – The method outlined in the post IS nic specific. Not all cards support changing your MAC through XP.

It looks to me like it’s dependent on the adapter.

@Transcontinental: No it can’t. MAC Addresses are hardware creator specific. So random characters will not result in a proper worked MAC Address.

@Eric Blue: Changing your MAC Address normally require you to reboot your system. At most, you might be required to disable/enable your network card for it to run again.

Is it possible that a MAC address be inconsistent otherwise than not being a combination of 6 pairs of numbers and characters ? I mean, just for the story, must those 6 pairs correspond to a criteria, could I for instance choose them random ?
