Of course you're correct!
So, what else is new? 😉
48-bits in a MAC address. That makes a bit more sense. After all, /64 is a nice power of two.
It's amazing, Ethernet addressing was developed in 1973. How prescient was Bob Metcalfe and his team to settle on 48-bit addressing! It's funny what one remembers. I recall sitting on the toilet at work in 1976 reading a EDN magazine article talking about how packet switched networks were the wave of the future. It was ten years later when I found myself pulling that yellow Thicknet coax around to set up our first Ethernet subnet. Now look at what we have!
Look up Ethernet Blue Book, to see the first official spec from 1980. However, originally, Ethernet had an 8 bit MAC address, just like ARCnet.
I was just going by my friend ChatGPT. Regards, Lew Ethernet addressing was invented in *1973* as part of the development of Ethernet technology at Xerox PARC (Palo Alto Research Center) by Bob Metcalfe and his team. Ethernet was designed to facilitate local networking for computers and initially used a simple 48-bit addressing scheme to uniquely identify each device on a network, which remains the basis for modern Ethernet MAC (Media Access Control) addressing. The formal publication of Ethernet, including its addressing method, appeared in a 1976 paper titled /"Ethernet: Distributed Packet Switching for Local Computer Networks"/ by Metcalfe and David Boggs. Ethernet and its addressing became standardized in 1980 as part of the IEEE 802.3 standard, which formally established Ethernet technology for widespread use.
