i am studying off this


but my question is if ip address is for end to end communication , how is the end to end happening when all it is just hop to hop using MAC address?i understand they gotta encapsulate the L2 header with a MAC but please forgive me if i am wrong but it seems like IP addresses's use in network communication is to get the MAC address.I am not talking about in LAN network communication,i understand mac is important there , talking about network to network.Is ip address just a bunch of hop to hop mac communication?

  • Not all L2 networks are MAC based, but on those that are the addresses are required.
