I am trying to understand the Internet Protocol Suite as described by Wikipedia. What is confusing me is the Internet Layer.
So, to see if I understood it, this layer is simply the IP header and data. TCP or UDP or TCMP, or even ARP would be an inner layer the transport layer. So this layer is the IP protocol or IPv4/6.
Granted I understand correctly, would it be possible to have two nested Internet layers? Like an outer layer that has one ip address then another with a different layer like subnet address?
