Can you tell me about I.P. Addresses?

Hello Apple Community,

I have taken an interest on IP addresses, and I would like to know more about it and check if my understanding is correct. Of course, I am in an Apple Discussion site, so I would like my answers based on a Mac Yosemite.

These are the questions I would like to ask (You can just answer on the parts of what you know):

Basic Questions:

1. How does IP addresses work?

2. What are the differences between public and private IP addresses, and how are they used differently?

3. What are the differences between dynamic and static IP addresses?

4. What kind of information can one know by just knowing an IP address?

5. How does routers, modems, etc. work in the case of IP addresses?

6. How are IP addresses assigned?

7. How does IP banning work?

8. How can you check who is your ISP and contact your ISP?

9. How can you change your public and private IP address?

More Personal and Specific Question:

1. We have 2 routers in our household. When I changed the wifi network and restarted my browser, it was still the same IP address. Is it supposed to be like that?

[But when I was in different place (same country) and had different network (same computer), the IP address changed.]

Thank you in advance,

Littered

I suggest you research basic networking. This is not a subject to be discussed here on the forum, and it would take a great deal of room, given the number of questions that you posed.
