Not so long ago I wrote:

because all the other ones I could find got the handling of the address
scope and OUI wrong.

This is what I use:

$ cat /usr/local/bin/genmac
#!/bin/bash
prefix="00:16:3E"

mac="$prefix"
for seqnum in 1 2 3 ;do
part=`dd if=/dev/random bs=1 count=1 2>/dev/null | xxd -ps -u`
mac="$mac:$part"
done
echo $mac
