Router(config-dhcp)# default-router A.B.C.D

Note: You can specify up to eight DNS server IP addresses.

Use the no form of this command to remove the configured default router.

8.1.11 Configuring the Address Lease Time

By default, each IP address assigned by a DHCP server comes with a one-day lease, which is the amount of time
that the address is valid. To change the lease value for an IP address, use the following command in DHCP pool
configuration mode:

Router(config-dhcp)# lease <1-43200>

The numeric argument is the duration of the lease in minutes. Use the no form of this command to reset to the default
one-day lease.

8.1.12 Configuring a DHCP Server Boot File

The boot file is used to store the boot image for the client. The boot image is generally the operating system the client
uses to load. To specify a boot file for the DHCP client, use the following command in DHCP pool configuration
mode:

Router(config-dhcp)# bootfile filename

Use the no form of this command to remove the DHCP Server Boot File.

8.1.13 Configuring the DHCP Address Range

To specify the IP Addresses (single or range) to be dynamically assigned, use the following command in DHCP pool
configuration mode:

Router(config-dhcp)# range A.B.C.D [A.B.C.D]

Use the no form of this command to remove the address range.

8.1.14 Configuring Manual Bindings

An address binding is a mapping between the IP address and Media Access Control (MAC) address of a client. The
IP address of a client can be assigned manually by an administrator or assigned automatically from a pool by a
DHCP server.

Manual bindings are IP addresses that have been manually mapped to the MAC addresses of hosts that are found in
the DHCP database. Manual bindings are stored in flash file on the DHCP server. Manual bindings are just special
address pools. There is no limit on the number of manual bindings, but you can only configure one manual binding
per host pool.

Automatic bindings are IP addresses that have been automatically mapped to the MAC addresses of hosts found in
the DHCP database. To configure a manual binding, first create a host pool, then specify the IP address and
hardware address of the client or client identifier. The hardware address is the MAC address. The client identifier,
which is required for Microsoft clients instead of hardware addresses, is formed by combining the media type and the
