At the present time, most IP implementations consider any IP address
in the range 240.0.0.0 through 255.255.255.255 to be invalid as the
source or destination of a datagram. The check for such "illegal"
addresses may occur in many places, including at datagram receipt,
before IP datagram transmission, when an IP address is assigned to a
network interface, or even by router and firewall configuration
parsers.
