A roaming host is a host with a dyna> Macro (anchor)
mically assigned IP address and a specific set of properties and DHCP options. When you create a roaming host for a network device, the device can receive any dynamically assigned address from the network to which it belongs. You can create roaming hosts for devices, such as laptop computers and mobile phones, that require different IP addresses each time they are moved from one network to another and require a unique set of DHCP options.
You can configure IPv4 addresses, IPv6 addresses, or IPv4 and IPv6 addresses for roaming hosts that require both types of addresses. When you configure IPv4 addresses for a roaming host, you must specify the host MAC address or a DHCP client identifier that the appliance uses to match the host, and specify DHCP options for the host. The appliance assigns an IP address from the DHCP range associated with the network from which the address request originates. You can configure an IPv6 prefix or address for a DHCP client. When you do, you must specify the DUID of the host so the appliance can use the DUID to match the host.
A roaming host also receives DHCP options from the Grid, member, network, or shared network with which it associates.
When you configure a roaming host, you must configure it in a specific network view. If you have multiple network views, you must specify the network view to which the requesting hosts belong so the appliance can assign addresses to the hosts from the networks within the same network view.
After you enable support for roaming hosts at the Grid level, you can add a roaming host that supports IPv4, IPv6, or both protocols. You can also convert an IPv4 roaming host to an IPv6 roaming host and vice versa, or convert an IPv4 or IPv6 roaming host to one that supports both IPv4 and IPv6.

Configuring Roaming Hosts
To configure a roaming host, perform the following tasks:
1. Enable support for roaming hosts at the Grid level. For information, see, *[Enabling](#AboutRoamingHosts-EnablingSupportforRoamingHosts)*[ ](#AboutRoamingHosts-EnablingSupportforRoamingHosts)*[Support](#AboutRoamingHosts-EnablingSupportforRoamingHosts)*[ ](#AboutRoamingHosts-EnablingSupportforRoamingHosts)*[for](#AboutRoamingHosts-EnablingSupportforRoamingHosts)*[ ](#AboutRoamingHosts-EnablingSupportforRoamingHosts)*[Roaming](#AboutRoamingHosts-EnablingSupportforRoamingHosts)*[ ](#AboutRoamingHosts-EnablingSupportforRoamingHosts)*[Hosts](#AboutRoamingHosts-EnablingSupportforRoamingHosts)*.
2. Add a roaming host.

Viewing Roaming Hosts
To view a list of roaming hosts in a specific network view:
1. From the **Data** **Management** tab, select the **DHCP** tab -> **Networks** tab -> **Roaming** **Hosts**.
2. From the Network View drop-down list, select the network view to which the roaming hosts belong.
3. The Grid Manager displays the following for each roaming host:
- **Name**: The name of the roaming host.
- **Address**: The IP address of the roaming host.
- **Comment**: The information that you entered for the roaming host.
- **Site**: The site to which the template belongs. This is one of the predefined extensible attributes.
You can select **Disabled** and available extensible attributes for display.
You can also do the following:
- Sort the displayed data in ascending or descending order by column.
- Use filters and the **Go****to** function to narrow down the list. With the autocomplete feature, you can just enter the first few characters of an object name in the **Go****to** field and select the object from the possible matches.
- Create a quick filter to save frequently used filter criteria.

Deleting Roaming Hosts
To delete a roaming host:
1. From the **Data** **Management** tab, select the **DHCP** tab -> **Networks** tab -> **Roaming** **Hosts** -> *roaming_host* checkbox, and then select **Delete** or **Schedule** **Delete** from the drop-down menu.
