While imaging some computers today, I started to wonder... what if two LAN MAC addresses on two different computers matched?... That would cause some problems. I later came to understand that the MAC address' 48-bit address space contains potentially 248 or 281,474,976,710,656 possible MAC addresses. [ in other-words, a lot of networking devices ]
How are these MAC addresses determined?
Will we ever run out of them? ( I know the second question is speculation, but there are a lot of devices that require a mac addresses...)
Do MAC addresses get recycled?
