How to get client's IP address using JavaScript? [closed]
(31 answers)
Closed 6 months ago.
I'm looking for a resolution, how can I get user public IP using only my page. My assumption is not connect to external applications to keep application safe. Page has been built with a ReactJS. Is it possible to do from browser and only JavaScript level? Or do I have to create my custom API to get user IP?
Thanks you advance.

No, there is not.
You can obfuscate and minify your code, but that doesn't help since your users can look at their browser's Network Inspector instead.

I am new to penetration testing. My requirement is to update registry values from browser using a client side programming language like javascript. Is it possible?
No, JavaScript can't read / write arbitrary files to the hard disk, copy them or call programs. It does not have direct access to the operating system.
This is done for the security of users, so that an attacker could not use JavaScript to obtain personal data or somehow damage the user's computer.

They are not the same thing at all: you can use them in a similar way, but they serve different purposes.

Get MaxMinds GeoLite GeoIP databases. From there on, you can compare your visitors IP up against that database.

Is possible read the browser history with Javascript? If the answer is Yes, how can I do it?
I want to read it and save it in a JS variable.
No. Other sites visited by a user are their business, not the business of every website they visit. Browsers do not expose that information to web sites.
Browsers go to pretty serious lengths to plug anything that could leak a user's history to websites
In general history is protected by the browser against javascript accessing it except through back and forward functionality.
