    my isp has given me a web portal in which i can login and see my usage details ..but whats more imp is its also shows the ip address and my mac address…how my isp tracking my mac address ?



    It is probably the MAC of the outside interface of your home router, which they would necessarily know in order to authorize the router on their network and, of course, send you data. But there is nothing stoping them, if you are using a router provided by them, from having it pass data about devices attached to your inside network through in certain contexts. Software is software, after all.



    an rj45 cable provides me a internet connection right from my isp office , i can attach it to any device and authorize the pppoe connection by using the given credentials to me , and i use a tplink modem /router to have wifi ,as what i know the isp should not be able to identify any device behind the router , but the login portal(used to track my usage) is showing every device (including mobile phones) mac address . how’s that even possible ?? by the way i bought the router from online not from isp .



    Unless something isn’t setup properly, your MAC Address should never leave the internal network. The router should be the last place your MAC traverses. Someone please correct me if I am wrong on that.



    Your MAC Address is from the Router, Level 2 of the OSI model, it is just to uniquely distinguish a device from other devices. It is primarily to help you. The Router should be the last device that sees MAC Addresses, unless your MAC Address is getting recorded and sent to a database. My guess is that the portal that you’re describing lives on your Router.



    I agree with dragon, odds are the “portal” is on your home router as layer 2 addresses( mac address) are NOT sent on from the router.
