The derived addresses have LAA(Local Administered Address) bit set, and only the first byte is changed. Take the 00:03:7f:xx:xx:xx as example to derive: addresses[0] is unchanged, it's siill 00:03:7f:xx:xx:xx, addresses[1] is 02:03:7f:xx:xx:xx, addresses[2] is 12:03:7f:xx:xx:xx, addresses[3] is 22:03:7f:xx:xx:xx, addresses[4] is 32:03:7f:xx:xx:xx. However as only 3 addresses are reported now, so addresses[3] and addresses[4] aren't actually derived.
