How can i detect a visitor if ip adress changed

What exactly are you trying to do?

What language are you planning on using?

From just IP tracking, to cookies to creating a session and storing it - a lot can be done.

But you need to define your end goal.
 
hello brothers
How can i detect a visitor if ip adress changed
Several ways:
- plant a cookie on your visitors' browser: cookies are not specific to a ip address and will be stored on their browser as long as a proxy has been setup appropriately that doesn't intercept response headers.

- track with browser fingerprinting: if cookies don't work, you can make a fingerprint of your user's browser/device with javascript. As long as the User is not a privacy conscious freak who thinks he is being tracked by the FBI, their profile will be 99% unique and they can easily be tracked with a fingerprint.

You'll need to fingerprint the visitor somehow. Either cookies or some other more advanced technique. Then just save their ip to a database and compare history.
 
I agree on the use of visitor tracking tools. Though I have not used it yet, I'm also interested on adding this tool. We should be able track visit inspite IP changes.
 
Hi, to detect a returning visitor whose IP address has changed you can try to use browser cookies or browser fingerprinting techniques. Cookies can track users who have previously visited your site, while browser fingerprinting involves collecting various data points from a user's browser (like browser type, screen resolution, installed fonts) to create a unique identifier. Keep in mind the importance of respecting user privacy and adhering to relevant laws and regulations regarding data collection.
 
@Comsign what if they're using antidetect browsers how do you detect them if they're using a 4g proxy
 
You'll need to store a cookie with the IP and when the user comes back, detect the cookie and check the IP
