A utility to return IP address, city, state, zip country

I am not sure about the rate so please include your rate! I need a utility to be developed in c# and asp.net that once the visitor visits a page it should: 1. Find the IP address of the visitor 2. Find the city, state, zip code, and the country (which ever applies) - If the visitor in the US - zip code is required The procedure FindVisitorInfo() will be called in Page_Load() private void Page_Load(object sender, [login to view URL] e) { if(! [login to view URL]) { err = FindVisitorInfo(ref string ip_addr, ref string city, ref string state, ref string zip, ref string country) } }
