It is technically necessary, because DHCP clients do not have IP addressing
information when they begin the communication; everything is done using
ethernet broadcasts. Such packets cannot be acquired using a standard
socket bind, so the server application needs to listen at a lower level than
the TCP/IP stack allows.
