To specify the IP address and network mask for a manual binding to a Dynamic Host Configuration
Protocol (DHCP) client, use the host DHCP pool configuration command. Use the no form of this
command to remove the client’s IP address.
host address [mask | /prefix-length]
no host
Syntax Description
Defaults
None
Command Modes
DHCP pool configuration
Usage Guidelines
This command first appeared in Cisco IOS Release 12.0(1)T.
If the mask and prefix length are unspecified, DHCP examines its address pools. If no mask is found
in the pool database, the Class A, B, or C natural mask is used. This command is valid for manual
bindings only.
There is no limit on the number of manual bindings but you can only configure one manual binding
per host pool.
Examples
The following example specifies 10.12.1.99 as the client’s IP address and 255.255.248.0 as the
subnet mask:
host 10.12.1.99 255.255.248.0
