Change the MAC address of your network card.
Techies know that everyone’s network adapter has what is called
a MAC (Media Access Control) address that uniquely identifies it.
Each is as individual as a fingerprint. This MAC address is used
for many different purposes; for example, some networks examine the
MAC address of every device trying to connect to it, and lets only
those through that it knows are safe. Just as there are ways to
change fingerprints, there are ways to change MAC addresses. You
might think that changing your adapter’s MAC address is beyond the
capabilities of mere mortals. It’s not, however; if you use the
free Technitium MAC Address Changer you can do it with a few clicks
of your mouse.
That MAC address is hard-coded directly into the adapter, so you
might think it can’t–or shouldn’t–be changed. In fact, though,
there’s a way to “spoof” that MAC address, and essentially make the
adapter’s address look like a different one. Hackers sometimes use
this technique to hide their tracks, or slip undetected into
networks. But there are also legitimate reasons people might want
to do it as well. For example, some network providers such as cable
companies register your MAC address when you sign up, and if that
MAC address changes, you’ll have to re-register via tech support,
always an unpleasant process. So if you get a new PC, you might
have to call in. You can instead change your MAC address. Security
professionals can do this, too, to give a PC a MAC address that
isn’t authorized to access a network, and then used that
unauthorized MAC address to test network security.
When you launch Technitium MAC Address Changer, it looks into
your system and identifies every adapter’s MAC address. It also
identifies the manufacturer of the adapter, its maximum network
speed, and other information as well.
If you’re a true techie, you can manually enter the MAC address
yourself. But MAC addresses are complicated, and it’s possible to
enter an incorrect one. So MAC Address Changer takes care of the
task for you. Click Random Mac Address, and it generates one for
you. If you want, you can even select from a list of manufacturers,
such as Cisco, Texas Instruments, and many others, and it will
generate a MAC address used by one of those manufacturers. Click
Change Now! and the MAC address is changed. To change the address
back to the original, click Original MAC.
If you want to change your MAC address, Technitium MAC Address
Changer is a superb tool. It’s even useful for those who are just
plain curious about what’s under the hood in their PC.
