After the importing of IP addresses from a spreadsheet it is possible that one or more IP addresses may have been imported without being assigned to a managed subnet. In order to properly manage your network, Orion IPAM requires that all IP addresses are assigned to a managed subnet, even if the managed subnet contains only a single IP address. If Orion IPAM is unable to locate a configured subnet for each imported IP address, the following warning banner displays above the Manage Subnets and IP Addresses view:

The following procedure assigns parent subnets to orphaned IP addresses to enable their management by Orion IPAM.

If you try to manage more IP addresses than your current license allows, Orion IPAM will add as many IP addresses as allowed. The remaining addresses will be added as orphaned IP addresses.

To assign a parent subnet to an orphaned IP address:

  1. Click Assign parent subnets to orphaned IPs in the warning banner.
  2. Check a single orphaned IP address.
  3. Click Assign Subnet.
  4. If you do not want to use the default Subnet Name provided by Orion IPAM, provide a new Subnet Name for the new parent subnet. Orion IPAM suggests both a Subnet Address and a CIDR prefix length based on the actual orphaned IP address. The default Subnet Name provided by Orion IPAM is a concatenation of the Subnet Address and the CIDR prefix length.
  5. If you do not want to use the default Subnet Address and CIDR prefix length provided by Orion IPAM, provide a new Subnet Address and an appropriate CIDR prefix length for the new parent subnet.
    • Orion IPAM suggests both a Subnet Address and a CIDR prefix length based on the actual orphaned IP address. For more information about CIDR and subnet addressing, see Networking Concepts and Terminology.
    • Orion IPAM instantly confirms the validity of provided Subnet Address and CIDR prefix length combinations. For more information about CIDR and subnet addressing, see Networking Concepts and Terminology.
  6. These fields are optional; provide a Description, VLAN ID, and Location for the new parent subnet.
  7. Use the slider to set the Scan Interval.
  8. If you do not want Orion IPAM to automatically scan your new parent subnet for changes, check Disable Automatic Scanning.
  9. Click Save when you have completed configuring your new parent subnet.
