Hello

I'm a bit confused about these two protocols.

If i send a message from one pc to another in internet, is it first
encapsulated into IP packets and after that MAC packets?

I've understood that all information is always encapsulated into IP packets
in internet traffic.

IP packets are used in communication between the two softwares, and MAC
packets are used in communication between the two hardwares.

IP packets are by no means the only kind of packets which can be transmitted
from one MAC address to another.

So the packets moving around in the internet are actually MAC packets?

Thanks for the help

Only Ethernet has MAC packets. I can't remember how the other hardware
protocols work.

I'd understand that the routed packets in internet are IP packets.

And MAC packets are only used inside LAN and other local networks. In this
kind of enviroment the IP packet can be inside MAC packet (or in other words
MAC frame).

It's hard to find clear schema on how the MAC and IP packets work. All the
websites talking about this matter have only partial or even false
information.
