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.
