Re: what about 48 bits?

I've seen duplicate addresses in the wild in the past, I assume there is some amount of reuse, even though they are suppose to be unique. -jim On Sun, Apr 4, 2010 at 11:53 AM, A.B. Jr. <skandor@gmail.com> wrote:

Hi,

Lots of traffic recently about 64 bits being too short or too long.

What about mac addresses? Aren't they close to exhaustion? Should be. Or it is assumed that mac addresses are being widely reused throughout the world? All those low cost switches and wifi adapters DO use unique mac addresses?
