inside your handler function call r.RemoteAddr to receive ip:port
like this:
func renderIndexPage(w http.ResponseWriter, r *http.Request) { ip := strings.Split(r.RemoteAddr,":")[0] }
update 02/15/2017 as @Aigars Matulis pointed out, in current version there is already a function todo this
ip, _, _ := net.SplitHostPort(r.RemoteAddr)
