[Jose Manuel Arronte Garcia]

I thank you all for those comments about my post on IP<->MAC, you all let me know about the previous non-existence of MAC(ethernet)   I may sound dumb, but, what mechanisms did you have in lower layers previous to MAC implementations? it was all done by IP addresses?   Not everything has a MAC address nowadays, but, does everything (in an IP network) need an IP address?   Saludos.
