<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>
