hi...

1. I've heard of static IP and dynamic IP. Some ISPs will provide static IP while some provide dynamic IP. What is their difference and why one uses static IP while the other do not?

2. Is IP address the only thing to represent the uniqueness of somebody on the web?

3. If I change my IP, while using the same computer in the same location, would anyone or any sophisticated website be able to know I am the same person after changing the IP ? (Except ISP and Police )



 
Solution
1: Static will be static, as opposed to the dynamic one. It's neat for connecting to networks where ip's are whitelisted, like a VPN or hosting something from home, a server or whatever, RDP etc
Using a static could mean that you may be a bigger target for hackity stuff since it never rotates. I wouldn't personally worry about that though.

2: Yes. And no. It is, if it's static an accurate pinpoint at you. But your browser sends on heck of a lot of information to "the internet" that's is a pretty unique fingerprint.

3: Yes, basically :)

Solution
1. Static IPs cost more money. This is because the ISPs can charge for them, as you pretty much need a static IP to host a server.
2. Cookies also represent you on the web, and cached data.
3. If you clear your cookies and cache as well as changing your IP, no website would be able to tell you were the same person.

"“Browser fingerprinting” is a method of tracking web browsers by the configuration and settings information they make visible to websites, rather than traditional tracking methods such as IP addresses and unique cookies"
