You can they can detect/monitor your IP but you can change your IP by resetting your modem. However, MAC adress is something device-specific. Every computer has a specific MAC adress. I wonder if sportsbooks can track/monitor your MAC Adress? Is it technically possible?

MAC: A Media Access Control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment.

[Russian Rocket]

piece of cake...of course your MAC address can be tracked.

[soul786]

yes they can, your mac address is in EVERY packet sent to an end node on the internet.

[NunyaBidness]

Yes, and you can spoof your MAC address easily.

They can't read your MAC address without executing some sort of program on your PC with permission to read it.

Client side stuff like Javascript etc does not have permission to access it. (some vulnerable systems will give it up with ActiveX)

Your local router strips out your MAC address and uses its own from that point, as does the next hop etc etc.

Add to that that cell phones and dial up modems don't send any MAC info and it starts to become a near pointless exercise for books to bother trying to track you by MAC address.

One person speaks sense in this thread. The others...idiots.

The force in this thread is strong, my young Jedi.

Optional is 100% correct

Please don't PM me about this anymore Sawyer.

This is the sort of thing you are trying to defeat

On top of them probably profiling the IPs you keep signing up from, checking that against known proxy lists that companies maintain for them, looking at your username/password patterns, signup time or a myriad of other stuff security experts paid to think about this all day could come up with.

You don't have the technical knowledge to trick the system the way you are trying to. Do yourself a big favor and forget this before you get yourself in some sort of pain in the ass trouble. ;-)

Edit: PS.. the 1 account you mentioned could easily be a 'honeypot' they plan to use to reel you in to gain enough evidence against you. Don't just assume they didn't notice it if created the same way as the others.

This is true, sportsbooks are not able to track you by your MAC (possible but highly unlikely).

Your home router does NAT translation, which is used for your devices on your home network to communicate to other devices by traversing the internet while your home network is using a single IP.

Thanks for the replies fellas.

You beat http://en.wikipedia.org/wiki/Device_fingerprint with setting up a http://en.wikipedia.org/wiki/Virtual_machine

iesnare / mpsnare and local flash storage are quite able to track and identify things to gaming/gambling sites as well ...

So many cases of people not getting their money back because of suspicious ip or stuff like that. Why bother?
