Once I realised that IPv6's fixed sized node addressing model was
similar to Ethernet's, I then started wondering why Ethernet was like
it was - and then found a paper that explains it :

"48-bit Absolute Internet and Ethernet Host Numbers"

Question. Whats the ethernet 48-bit MAC space usage atm? Does anyone
have a graph showing an E-Day? :)



Apparently there's a foreseeable one, hence EUI-64s. Novell'll have to
extend their IPX node addressing to 64 bits.
