Using sniffed macs on the same subnet?

[stuholds]

This may seem like a silly question, i would just like some clarification.

If I was to use a sniffed mac from my own subnet, would this cause a DHCP failure.

Am I right to think, that if 2 of the same macs are on the same subnet and being used would they both be signed the same ip, thus causing a clash and no internet service being offered?????

As I said just trying to get clarification.

Thanks

they'd clash and more often than not cause the isp to investigate due to subscribed modem being in a reboot loop

Thanks for the good advice mate
