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

 Above is some code to get you started.  You will need to add it to your controller or controller extension.

Thanks for your reply,

 

can you brefiely explain me what is caching.And I want the Mac address of the local system.

For caching on force.com, see this documentation.

 

I don't think you will be able to display the MAC address of the local system for technical reasons.  Basically, the MAC address is at the data link layer of the OSI model and as such won't be accurate at the next hop down from the orignal machine as the next device (host/gateway/router) will put their MAC address in that place. 

 

I could be wrong and the MAC address could be in a header but I seriously doubt it.

There's nice code for this from Anthony Coleman (http://www.forcedisturbances.com/2012/05/limiting-access-to-visual-force-pages.html). 
public static String GetUserIPAddress() {
 string ReturnValue = '';  
   
 // True-Client-IP has the value when the request is coming via the caching integration.
        ReturnValue = ApexPages.currentPage().getHeaders().get('True-Client-IP');
 
          // X-Salesforce-SIP has the value when no caching integration or via secure URL.
        if (ReturnValue == '' || ReturnValue == null) {
         ReturnValue = ApexPages.currentPage().getHeaders().get('X-Salesforce-SIP');
        } // get IP address when no caching (sandbox, dev, secure urls)
 
         if (ReturnValue == '' || ReturnValue == null) {
         ReturnValue = ApexPages.currentPage().getHeaders().get('X-Forwarded-For');
        } // get IP address from standard header if proxy in use
 
 return ReturnValue;
  
} // GetUserIPAddress

Any suggestions on how to do this if ApexPages.currentPage() isn't defined? (I.e. under Execute Anonymous or JavaScript remoting?)

In Execute Anonymous or Remote Actions the running user IP address is available from the session management class: 
String ip = Auth.SessionManagement.getCurrentSession().get('SourceIp');
