 ### Address range
 
-There is also an option to provide **Address range** for virtual machines for the labs. If the address range is provided, all the virtual machines in the labs under the lab account will be created in that address range. The address range should be in CIDR notation (e.g. 10.20.0.0/20) and not overlap with any existing address ranges.  When providing an address range, it's important to think about the number of *labs* that will be created and provide an address range to accommodate that. Lab Services assumes a maximum of 512 virtual machines per lab.  For example, an ip range with '/23' can create only one lab.  A range with a '/21' will allow for the creation of four labs.
+There is also an option to provide **Address range** for virtual machines for the labs.  The **Address range** property only applies if **Peer virtual network** is enabled for the lab.

 If the **Address range** is not specified, Lab Services will use the default address range given to it by Azure when creating the virtual network to be peered with your virtual network.  The range is often something like 10.x.0.0/16.  This may lead to ip range overlap, so make sure to either specify and address range in the lab settings or check the address range of your virtual network being peered.
