Hello, I'm currently working on a site (only to get better with my programming, nothing fancy) and I'm having few problems. I got the basics down, HTML, PHP, etc. however I'm trying to find a way to interact with the user's computer. Now, I understand in order to do that I need to use IP addresses. I read a bit about them and I understand that each computer gets his own IP. Every IP address is unique and permanent(?), using it we can identify different computers.
Questions:
1) Is there anyway to get a computer's IP address and restore it using PHP or HTML?
2) Does networks or routers affect IP addresses? If so, how?
3) Are IP addresses really permanent? If not how can I deal with it, is there any way to trace the previous IP address?
4) What are local IP addresses exactly?
Any answer would be much appreciated.
