Your computer itself has a M.A.C because of the port in the back for Ethernet.
Further proof of your complete lack of knowledge. I'm not even angry at you anymore, it's very clear that you're completely misinformed and lying to save face. Certainly, no tech company worth their salt would ever hire someone as misinformed as you, nor would any legit education institute certify your utter lack of knowledge. Let's see, how to best phrase this all;
Your internet comes in through the wall, via coaxial or RJ-12 or even fiber optic. This connects to your modem, which changes the interface over to ethernet. If you need multiple computers to connect to this modem, you connect the modem to a router, and the computers to the router. The router is not needed if you have only a single computer connected to the modem via ethernet.
The MAC address of an internet-capable device refers to the unique hardware ID that marks it as different from every other internet-capable device. The modem has a MAC, the router has a MAC, each computer has a MAC (sometimes multiple, if you have more than one NIC in a computer). The sole purpose of this MAC is to give each computer its own way of IDing itself as different from the rest of the computers in the world. Think of it like a person's ID card. It proves you are who you say you are.
The IP address of an internet-capable device is used to logically locate a device within a network. Via the process of subnetting, large networks can be broken down into smaller branches containing groups of IPs. The IP address tells other devices on the network what subnet the device is in, and how to send data to it. It can get even more confusing than that, you can create private networks inside public ones, which is actually how your own network at home works. At the very top is the public internet, with (before IPv6 came out) a small pool of available addresses. The ISPs and telecoms all lease or own different branches in the public internet. Bigger companies have more addresses available to them than smaller ones.
To save on space when you sign up for internet access, your ISP gives you only one IP address. If you have more than one device, you usually use a router to create a private network inside your home. This allows you as many IP addresses as you want (without using up IPs on the public internet), as the network is only communicating with the public internet via the modem and its one IP address, which translates the internal IP addresses of your private network into the external IP address of your modem for outgoing and incoming communication.
Now, you can spoof a MAC address, which makes the device appear to have a different MAC than it originally did. However, this doesn't actually change the MAC itself; the device tells all the devices it communicates with that its MAC is different and all communications to it will need to use this different MAC. However, once these communication data arrive at the device, it performs a translation and converts this different MAC back to its original, hence why it is called "spoofing". IP addresses can also be spoofed, but since the IP acts as directions to your computer, instead of an individual ID to your computer (since there are so many IP addresses available, and private networks allow even more, the IP is never unique in the world), you can think of it like your street address, used when mailing something to you.
That's actually a great analogy, your private network is like your house, your MAC is your name, and your IP is your street address. Someone mails you something by using your street address to make sure it gets to the right house, and your name to make sure it gets to the right occupant.
The essential thing to understand here is that a MAC address and an IP address are
completely unrelated to each other. If you have only one, you can't find the other. Yes, you need both to function on the internet, but they operate
independently of each other and are
not tied to each other
in any way. Changing your MAC will
NOT change your IP, just as changing your IP will
NOT change your MAC.
As for how MAC and your internet service are related; Your ISP goes to their own router config page and inputs your modem's MAC information. This is how the data that is destined for you actually gets to you. If you change the MAC of your modem, your ISP will still have its own router configured to route data to the old MAC, and you won't connect to the internet. Think of it like this, if you change your address without telling the Post Office, then your mail obviously won't get to you. If your setup is Modem>Router>PC, and you change the MAC of the router itself, this won't effectively change anything, as the only devices which need to know your router's MAC to communicate with it are the modem and the PC, and they will both get the updated MAC when the router broadcasts to redetect the network structure.

Actually, it will if you have a dynamic IP. When you power-cycle, your modem loses its lease on its IP address. Static IPs just get reassigned the same one, but Dynamic IPs will register a new one in the block available to the ISP.

If you can do it and prove it, why don't you? Screenshots are far too easy to edit to win an internet argument, so why don't you make a youtube video of this successfully working? That video is far from legit, as I explained earlier, the maker had advanced knowledge of compatible MACs ahead of time, and the scores of complaints in the comments lamenting it as not working remove any further doubt.

You are not a Network tech or even involved in tackling them, I'd be scared to allow you to touch my network.
Why don't you post some proof? Instead of making personal attacks against me and my knowledgebase, why not go ahead and prove that it can work? Any person reading the conversation between us will be able to tell very easily which of us has more experience and actual hands-on knowledge of networking. Hint: it's the guy explaining every detail of every step of the processes involved while posting verifiable links, not the guy who posts a single youtube video and slings insults with nothing to back up his claims.

Even if you don't care for wikipedia, I posted two links that are the actual Request For Comments describing how MAC and IP work. These RFCs are the internet
standards, set by the IETF that all ISPs, telecoms, and manufacturers have agreed to and adhere to.

Due to the unverifiable nature of the miasma-like internet, I too can post any facebook page I like and claim it as mine. Facebook proves nothing, images can be doctored, you have no proof of anything and I highly doubt you are certified in networking, let alone employed in it. Also, your spelling and grammar are both atrocious.

To any other posters reading this topic, please be aware that the
only way to change your external IP address is by power-cycling your router (if you have a dynamic IP) or by using a proxy to spoof your IP (if you have a static IP). Changing your MAC address does
NOT change your external IP address, unless you have a dynamic IP and power-cycle your router in the process.
