how do I find what MAC address web pages see as my MAC address
or to put it another way how do I find out what MAC address is being sent out as mine
|
Web sites don't see MAC addresses. Those don't make it past your local subnet.
|
AFAIK Wesites cannot see your mac address, just your ip. ' http://whatismyipaddress.com/ '

MACs are Layer2 addresses, they're seen only on subnets. What the webserver will see from you will be your IP, or your gateway's IP, your Layer3 address, (all assuming you're using TCP/IP, of course)
|
IF I told you guys how I know that web sites can see your MAC address I would be baned from this forum
|
No. The web server will see a source MAC address, but this will be the MAC address of the gateway on the server's subnet, not your MAC address.
Slight correction: I have found a site that gives a method for getting it, using JavaScript. However, it:
So, the web server cannot get the MAC directly (unless the client is on the same subnet). It may persuade the client to give up the information, but it would be fairly easy for users to prevent. |

Your assertion conflicts with everything I know about networking. I have tried searching the web for a way to do it and found nothing, without using client-side code to send the info out. I am not persuaded. |

ISPs use dynamic IP addresses so a IP address dose not identify some one reliably BUT a MAC addresses do |

every time I reset my network connection with my ISP I get a new IP address dose this mean I can just set up a new account as a way around the ban? |
