Dest/Source Address of an Ethernet Frame

Would the destination and source address in an ethernet frame remains permanently throughout its routing? In other words, would it change as the frame is being routed?

Is there a particular reason that you ask?

I'd recommend reading a good book on networking if you want to study it in this detail.

I just suddenly got confused because after seeing that the 802.11 frames have 4 address fields that swap between the MAC addresses of the routers and computers, I start to wonder if the destination and source MAC addresses in the 802.3 Ethernet frame gets changes too.

Actually, I already have a book on networking and this question pop up in my mind after a while.

I remember that the source and destination MAC addresses in an Ethernet frame will never change from its original addresses but I just wanted to be sure that I am right.

So, would the MAC addresses in the Ethernet frame change?

I think you are misunderstanding Ethernet and routing. Ethernet is a Local Area Network protocol. Ethernet frames are not directly routed. And why would the MAC address matter once the packet has left the LAN?
