Prohibition of 1:N IP Address Assignment 
The DHCP server may assign plural IP addresses to a single DHCP client in case of plu-
ral DHCP requests from the DHCP client which has the same hardware address. Some 
network devices may need plural IP addresses, but most DHCP clients like personal 
computers need only a single IP address. In this case, you can configure the hiD 6615
