<title>Adding Multiple IP Ranges</title>
<note>
<para>The feature can only be implemented on IPv4 addresses.</para>
</note>
<para>&PRODUCT; provides you with the flexibility to add guest IP ranges from different subnets in
Basic zones and security groups-enabled Advanced zones. For security groups-enabled Advanced
zones, it implies multiple subnets can be added to the same VLAN. With the addition of this
feature, you will be able to add IP address ranges from the same subnet or from a different one
when IP address are exhausted. This would in turn allows you to employ higher number of subnets
and thus reduce the address management overhead.</para>
<para>Ensure that you manually configure the gateway of the new subnet before adding the IP range.
Note that &PRODUCT; supports only one gateway for a subnet; overlapping subnets are not
currently supported.</para>
<para>You can also delete IP ranges. This operation fails if an IP from the remove range is in
use. If the remove range contains the IP address on which the DHCP server is running, &PRODUCT;
acquires a new IP from the same subnet. If no IP is available in the subnet, the remove
operation fails.</para>
<para>This feature is supported on KVM, xenServer, and VMware hypervisors.</para>
