OP: (feel free to put any questions about the lecture here!)
Uranus: Will IP v. 6 ever be implemented?
Vorash: What’s the difference between web and internet?
Carreras: is everything unowned now or are there parts of the internet that are owned
Blackeye: Do large technology companies have the ability to lobby the IETF?
Saturn: I understand how we might think of the actual network structure of the internet as unowned, but how has ownership of physical internet infrastructure changed over time?
Kamino: What are policy arguments in favor of owned vs unowned tech? Why might regulators prefer one to the other?
Venus: How are IP addresses generated and do they change over time (e.g., are they fixed and tied to a device or change each time one goes on the internet, etc.)?
Tethys: I get the hierarchy/polyarchy distinction (I think) but struggling to grasp what the owned/polyarchy quadrant encompasses. Are there instructive examples?
Kagen: Understanding a bit more of what the world wide web is, but what then is the Internet? What remains of it, are there uses that are distinct from the web? Does it matter?
Tollana: Any stories of government involvement with the IETF? I find it hard to believe such an important technology wouldn't attract CIA/FBI/etc..
Ban Gleán: What's the difference here between ownership of the software and ownership of the underlying hardware/networks?
Cantonica: what is a packet?
Sirius A: Does the IETF have any means of accountability that the public can use against its members?
Lantea: is it more economically viable to make owned or unowned tech/systems? what's the incentive to make unowned tech, like Apple II?
Oberon: Packet = a tiny piece of information a file is broken up into before it it sent across the internet
Phobos: What is the difference between IP and applications?
OP: @Phobos IP is an addressing scheme that the various devices that make up the internet (computers, routers, servers, etc) can use to send packets from one place to another. Applications are programs running on computers, some of which use the IP addressing system to allow the computers they're running on to communicate with other computers elsewhere in the world.
OP: @Kagen/Vorash, the internet refers to physical infrastructure (literally wires carrying bits) and low-level protocols (like the IP addressing scheme) that enable computers to send packets to one another. The web uses this infrastructure to enable browsers to send and receive HTTP, which encodes webpages like the one you're on – it's an application running on top of the web via servers and browsers.
OP: Here's a decent explanation in more depth:
Vorash: Is stuff on the internet still sent through physical wires?
OP: For the most part, yes! Data sometimes travels wirelessly (via cell networks, for example), but there's almost always a wire somewhere between the sender and the recipient :)
OP: For example, a cell company's wireless LTE network mostly just transports data to and from giant cell sites, which then put the data on a wire to wherever it needs to go.
OP: That's all because wired connections are super fast and reliable relative to wireless connections
OP: Also, the "wire" is often pretty different from the phone cables of yesteryear – a lot of it is fiber optic cable, which can transport literally millions or billions of times as much data (in the form of packets/second) as your average telephone line.
OP: For those wanting to learn more about this stuff, this is a pretty good (if old) guide:
