ELI5 How a cellular network handles IP addresses? Does it just act like a massive router? What is different between internet use via router or via LTE?

The whole point of TCP/IP is that *it doesn't care what you run it over*.  Wifi, Ethernet, LTE, DSL, Cable, ATM, etc...  You just encapsulate IP to run over that network and connect it to a router one way or another.  That router is connected to other routers over some *other* physical network but, as long as they both have the same network & speak TCP/IP, packets get routed.
