``` go import ( "crypto/rand" "fmt" ) func main() { buf := make([]byte, 6) _, err := rand.Read(buf) if err != nil { fmt.Println("error:", err) return } // Set the local bit buf[0] |= 2 fmt.Printf("Random MAC address: %02x:%02x:%02x:%02x:%02x:%02x\n", buf[0], buf[1], buf[2], buf[3], buf[4], buf[5]) } ```

<pre> import ( "crypto/rand" "fmt" ) func main() { buf := make([]byte, 6) _, err := rand.Read(buf) if err != nil { fmt.Println("error:", err) return } // Set the local bit buf[0] |= 2 fmt.Printf("Random MAC address: %02x:%02x:%02x:%02x:%02x:%02x\n", buf[0], buf[1], buf[2], buf[3], buf[4], buf[5]) } </pre>
