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
S223/S323 to prohibit assigning plural IP addresses to a single DHCP client.
To prohibit assigning plural IP addresses to a DHCP client, use the following command.
