Hi Michael, Unless the question specifically mentioned a particular dotted quad, whether an IP address or group is odd or even really only matters with the value final bit (remember that the dotted quad is just a handy representation of a 32 bit value for us poor humans) so if the last bit is a 0 it's even or 1 it's odd.
