A fabric administrator can define one or more ranges of static IP addresses for use in provisioning a network.

About this task

During multi-machine provisioning, every new multi-machine routed network allocates the next available subnet range and uses it as its IP space.

When a multi-machine is deleted, its allocated routed network profile range is released after the next static IP addresses workflow runs.

If a multi-machine blueprint contains a routed network profile but not an assignment for the routed network to component network adapters, a catalog item is created but machine provisioning fails with exception error. IP ranges in the routed network profile are listed as allocated but the IP addresses are in use. Ensure that you assign a routed network profile to multi-machine blueprints.


  1. Click the IP Ranges tab.
  2. Click Generate Ranges.

    You must type the subnet mask, range subnet mask, and base IP addresses on the Network Profile Information tab before you can generate IP ranges. Starting with the base IP address, vRealize Automation generates ranges based on the range subnet mask.

    For example, vRealize Automation generates ranges of 254 IP addresses if the subnet mask is and the range subnet mask is

  3. Click New Network Range.

    The New Network Range dialog box appears.

  4. Enter a name and, optionally, a description.
  5. Type an IP address in the Starting IP address text box.

    This IP address must match the base IP address in the routed network profile.

  6. Enter an IP address in the Ending IP address text box.
  7. Click OK.

    The newly defined IP address range appears in the Defined Ranges list.

  8. Click OK.
