    If I know an ip address is it possible for me to establish the mac address of the device to which it was allocated.

    i dont know what you mean completely, if you know your ip address and you want to know the mac address you can use a program like this-



    heres the link- http://www.klcconsulting.net/smac/

    if you want to know the mac address of another person just by knowing their ip is impossible, the mac address is determined by the connection, modem and the ISP, but like i said you can work out your own.

    I read somewhere that the ip address was allocated by referring to the mac address and that as such you could work out the mac address from the ip address which had been allocated to it.

    It's probably just something I picked up wrong so I thought I would ask.

    In the example you used above 192.168. etc doesn't that relate to the allocation being made on a LAN, say by a router.

    It's really whether an ip allocated on the internet itself would allow one to identify the mac address of the device which was connected to it.

    I know it doesn't for LANs and they are just allocated in the order that devices connect. However the lease can be held indefinitely, or be changed periodically based on the firmware settings in the router.

    yes, but each network card has its specific address, it is impossible to determine the mac of a pc out of your network for example mine.

    so the answer is no,
    only yours and others in your network.

    So if I knew your ip I couldn't work out the mac address of device you were using to connect to the internet. Is that correct.
