I. Configuring to assign IP addresses by static binding
Some DHCP clients, such as WWW servers, need fixed IP addresses. This can be
achieved by binding IP addresses to the MAC addresses of these DHCP clients. When
such a DHCP client applies for an IP address, the DHCP server searches for the IP
address corresponding to the MAC address of the DHCP client and assigns the IP
address to the DHCP client.
When some DHCP clients send DHCP-DISCOVER packets to the DHCP server to
apply for IP addresses, they construct client IDs and add them in the
DHCP-DISCOVER packets. The DHCP server finds the corresponding IP addresses
based on the client IDs and assigns them to the DHCP clients.
Currently, only one IP address in a global DHCP address pool can be statically bound
to a MAC address or a client ID.
