# Providing a specific DHCP address for client computers

You can set up your 802.11n base station or your Time Capsule to reserve a DHCP address for client computers on your AirPort network. When those client computers join your network, your base station or Time Capsule provides the same DHCP address to that client.

Your base station or Time Capsule must be set up to provide IP addresses to client computers on your network using DHCP before you can make a DHCP reservation.

## To set up DHCP reservations:

1. Open AirPort Utility, located in the Utilities folder in the Applications folder on a computer using Mac OS X, and in Start > All Programs > AirPort on a Windows computer.

2. Select the device you’re setting up, and then click Manual Setup. Enter the password if necessary.

3. Click Internet in the toolbar, and then click DHCP.

4. Click Add (+) below the DHCP Reservations list and follow the onscreen instructions to reserve a DHCP address. You will need to know the MAC address of the client computer you’re reserving the address for, and you will need to decide which address you want to reserve from the DHCP range.
