hellooow, have a quick question about mac addresses.
the standard says that the 1st 3 octets identify the manufacturer of the card. but how the manufacturer handles and classifies his 3 octets are not specified in any standard. so i would like to know if they all follow some kind of rule. To clarify the thing, i'll just give an example. Cisco classifies its mac addresses in different range, and they assign a specific range only for ip phones, another one only for access points, another one only for fiber cards, ... so basically, just by looking at the mac address you can identify the type of device that generated this packet.
so do other vendors do the same thing? has HP a specific range used only for printers? does linksys have a range for printing servers, another for wireless routers, another for voip devices, ...
basically, all i want to know is if i can define the type of device (printer, ip phone, access point, ...) just by looking at the (supposedly not spoofed) mac address...
taaaaaaaaaaaaaanks
