Not with 'ip' only, but still possible:
  # MAC="$(dd if=/dev/urandom bs=6 count=1 2>/dev/null \
           |hexdump -e '5/1 "%0x:" "%0x"' )"
  # printf "%s\n" "${MAC}"
  b9:41:54:af:d9:f0
  # ip link set address "${MAC}"

UNIX-powa! And it's probably not the only possibility. ;-)

But yes, it's a bit more involved than simply calling a single executable.

Yann E. MORIN.
