在Go中生成MAC地址

I'm looking for an example on how to generate a MAC Address in Go. I have found many examples on creating UUIDs but nothing on MAC addresses.

Can someone help?

Thanks, Ben

Here is how I would do it (playground)

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
", buf[0], buf[1], buf[2], buf[3], buf[4], buf[5])
}

Note the setting of the local bit which means it won't clash with any globally administered addresses (see wikipedia for more info)
