unrestricted proxy ARP feature is enabled, the router response is redundant and
might fool the IP client into determining that the destination MAC address within its
own subnet is the same as the address of the router.
DHCP
DHCP provides a mechanism through which hosts using TCP/IP can obtain protocol
configuration parameters automatically from a DHCP server on the network.
The most important configuration parameter carried by DHCP is the IP address. A
host must be initially assigned a specific IP address that is appropriate to the network
to which the computer is attached, and that is not assigned to any other host on that
network. If you move a host to a new network, you must give it a new IP address.
DHCP also carries other important configuration parameters such as the subnet mask,
default router, and Domain Name System (DNS) server.
An IP client contacts a DHCP server for configuration parameters. The DHCP server
is typically centrally located and operated by the network administrator. Because a
network administrator manages the server, DHCP clients can obtain reliable
parameters appropriate to the current network architecture.
For information about DHCP, see DHCP Overview Information.
