How can I show my IP Address in Salesforce Visualforce Page?

Hello Pranav,

Try this code

Apex controller :

public class IPAddress
{
public string myIPAddress{get;set;}
public IPAddress()
{
myIPAddress = ApexPages.currentPage().getHeaders().get('X-Salesforce-SIP');
}
}

VisualforcePage :

<apex:page controller="IPAddress" >
Your Login IP Address : {!myIPAddress}
</apex:page>
