How to get Ip Address of User in Salesforce Apex?

Hello Saurabh,

This may help you.
Below is some code to get you started. You will need to add it to your controller or controller extension

public static String GetUserIPAddress() {

string ReturnValue = '';

ReturnValue = ApexPages.currentPage().getHeaders().get('True-Client-IP');

if (ReturnValue == '') {

ReturnValue = ApexPages.currentPage().getHeaders().get('X-Salesforce-SIP');

} // get IP address when no caching (sandbox, dev, secure urls)

system.debug('USER IP ADDRESS: ' + ReturnValue);

return ReturnValue;

} // GetUserIPAddress
