To be clear, does this card have 4 different IEEE MAC address, so can be assigned 4 different IP on 1 (or 4) different subnets? I was just burned on a 2-port model which looks to Windows like only 1 port & the 2 ports act only like "built-in switch". I need this too like 4 x 1 port cards.

It has 4 different MAC addresses. Can be assigned 4 different IP addresses. I use them under Linux driver.
