hi guys it would be gr8 if some one can clear my doubt my question is first of all i would like to know somethin abt mac addresses and can we have 2 mac addresses and 2 ip adresses 4 a single computer if its possible can u guys please tell me how to do it ......thnx a lot
Thnx a lot Ltheobald i was jus trying to know whether its possible to have multiple macs n multiple ips anyways is it not possible to have 2 mac addresses 4 a single network card am a newbie dont mind if i post foolish question
a MAC address is a hardware encoded unique address generally encoded into the network adapter. Therefore, you could not have multiples for a single card.
Just as a curiousity ...
Windows stores the MAC address in the Windows registry, so if you manually edited the registry, you could fool Windows into thinking the NIC does have a different MAC address.
I haven't tried this, but ...
Certain ISP's make you register your MAC address. So if you could fool windows into sending an already registered MAC address, you could get around having to call the ISP and register a MAC for every device you're connecting to their network.
I didn't know this. Thank god my ISP doesn't do that as I have hooked a variety of PCs to my dsl connection for tech support purposes.
Yes, some broadband ISPs do this to prevent people from just going out and using someone else's broadband modem. But the MAC address they are registering is the modem's address, not a PC's address.

If you have two network cards, you can have two IP addresses (one per card), this is how internet connection sharing works on windows 2000/XP machines one card is connected to modem on one ip address and the other the local network.
If you wanted to have both ip addresses in the same range it might cause problems due to the computer name being duplicated.
On the mac addresses and ISP's they do register your mac address, it could be a router address or a modem linked to your network card on your machine. A lot of cable modems (mine included) will clone your pc mac address to get access to the ISP!
