When you configure an IPv4 network, you must assign either Grid members or Microsoft servers to the network. A network cannot be served by a mix of Microsoft and Infoblox DHCP servers. Multiple servers can serve a network, but Grid members and Microsoft servers cannot serve the same network.

A Grid member can serve only one network view. Similarly, a Microsoft server can serve only one network view. Therefore when you assign Grid members to networks, you must assign the members to networks in the same network view. For information, see Configuring DHCP for IPv4.

If you have enabled support for RIR (Regional Internet Registry) updates and are adding an RIR IPv4 network container or network to NIOS, Grid Manager displays an RIR section in the Add IPv4 Network wizard. You must enter RIR related information in this section in order for NIOS to associate the newly added network with an RIR organization. For more information about RIR address allocation and updates, see RIR Registration Updates.

To add an IPv4 network:

1. From the Data Data Management tab, select the DHCP tab -> Networks tab.
2. In the Networks section, select IPv4 IPv4 Network from the Add drop-down menu.
3. In the Add Add Network wizard, select one of the following and click Next:
   • AddAdd Network: Click this to add a network from scratch.
   • AddNetworkusingAdd Network using Template: To use a template, click this, and then click Select Select Template and select a network template. For information, see About IPv4 Range Templates 8. The appliance populates the template properties in the wizard when you click Next. You can then edit the pre-populated properties, except for Netmask.
4. Complete the following and click Next:
   • RegionalInternetRegional Internet Registry: This section appears only when support for RIR updates is enabled. For information about RIR, see RIR Registration Updates . Complete the following to create an RIR IPv4 network container or network:
     • InternetInternet Registry: Select the RIR from the drop-down list. The default is RIPE. When you select None, the network is not associated with an RIR organization.
     • OrganizationOrganization ID: Click Select Select Organization and select an organization from the RIROrganizationSelector dialog box.
     • RegistrationRegistration Status: The default is Not Not Registered. When adding an RIR allocated network, you can change this to Registered and select the Donotupdate Do not update registrations check box below. Note that when you select API as the communication method, the registration status will be updated automatically after the registration update is completed. However, when you select Email as the communication method, the registration status will not be automatically updated. If you are creating a new network and the registration update is completed successfully, the status will be changed to Registered. If the update fails, the status will be changed to Not Not Registered. The updated status and timestamp are displayed in the Statusoflast Status of last update field in the IPv4Network IPv4 Network Container or IPv4 IPv4 Network editor.
     • RegistrationRegistration Action: Select the registration action from the drop-down list. When you select Create, the appliance creates the IPv4 network and assigns it to the selected organization. When you select None, the appliance does not send registration updates to RIPE. When you are adding an existing RIR allocated network to NIOS, select None. When you are adding networks to an RIR allocated network (a parent network), select Create. Ensure that the parent network associated with an RIR organization already exists.
     • DonotupdateDo not update registrations: Select this check box if you do not want the appliance to submit RIR updates to RIPE. By default, the appliance sends updates to the RIR database based on the configured communication method.

The network is displayed in one of the following colors:

• • Yellow: The network is unmanaged.
  • Blue: The selected network.
  • GreyGray: The network is currently not available as a NIOS network object.
• Comment: The information you entered about the network.
• IPAM Utilization: This information is available for IPv4 networks only. It displays the percentage based on the IP addresses in use divided by the total addresses in the network. For example, in a /24 network, if there are 25 static IP addresses defined and a DHCP range that includes 100 addresses, the total number of IP addresses in use is 125. Of the possible 256 addresses in the network, the IPAM utilization is about 50% for this network. The appliance updates the IPAM utilization data immediately for a network container, but for a network it is updated every 15 minutes.
  The IPAM utilization data is displayed in one of the following colors:
  • Red: The IPAM utilization percentage is above the configured Trigger value.
  • Blue: The IPAM utilization percentage is below the configured Trigger value.
• Site: The site to which the network belongs. This is one of the predefined extensible attributes.
• Protocol: Displays whether the network is an IPv4 or IPv6 network.
• Disabled: Indicates if the network is disabled.
• Leaf Network: Indicates whether the network is a leaf network or not. A leaf network is a network that does not contain other networks.
• IPv4 DHCP Utilization: This information is available for IPv4 networks only. It displays the percentage of the total DHCP usage of theIPv4 network. This is the percentage of the total number of DHCP hosts, fixed addresses, reservations, and active leases in the network divided by the total number of IP addresses (excluding IP addresses in the exclusion range) and all DHCP objects in the network. Note that only enabled addresses are included in the calculation. It does not include abandoned addresses or leases. The appliance updates the utilization data approximately every 15 minutes. The utilization data is displayed in one of the following colors:
  • Red: The DHCP resources are 100% utilized.
  • Yellow: The DHCP utilization percentage is over the effective high-water mark threshold.
  • Blue: The DHCP utilization percentage is below the effective low-water mark threshold.
  • Black: The DHCP utilization percentage is at any number other than 100%, or it is not above and below any threshold.

...

• Cloud Usage: This field indicates whether this object is associated with any specific cloud extensible attributes or within a scope of delegation. It can be one of the following:
  • Cloud from adapter: Indicates that this object has been created by a cloud adapter and it may or may not be within a scope of delegation at the moment.
  • Cloud from delegation: Indicates that this object is within the scope of delegation or the object itself defines a scope of authority delegation, and it is not created by a cloud adapter.
  • Used by cloud: Indicates that this network or network container is associated with the extensible attribute Is External or Is Shared and the value is set to True, which implies the network is a private or shared network managed by the CMP, and it is not Cloud from adapter or Cloud from delegation.
  • Non-cloud: The object is a regular NIOS object and is not within the scope of any authority delegation nor is it associated with any of these extensible attributes: Cloud API Owned, Is External, or Is Shared. NIOS admin users can modify this object based on their permissions.
• Owned By: A cloud object can be owned by the Grid Master or the cloud adapter. When the object is created by the Cloud Platform member, this shows Grid. If the object is created by the cloud adapter, this shows Adapter.
• Delegated To: This tells you whether a cloud object has been delegated to a Cloud Platform Appliance or not. If the cloud object has a parent object and the parent has been delegated, this field shows the parent delegation and you cannot modify the field.
• Extensible attributes (Building, Country, Region, State, and VLAN): You can select the extensible attributes such as Building, Country, Region, State, and VLAN for display. When you enable other features such as RIR, Network Insight, and Cloud Network Automation, you can select additional attributes for display.

...

• IPAddress: The IP address of a DHCP object, such as a DHCP range, fixed address, reservation, host configured for DHCP, or roaming host with an allocated IP address. For a DHCP range, this field displays the start and end addresses of the range. For a host that has multiple IP addresses, each IP address is displayed separately. Note that the appliance highlights all disabled DHCP objects in gray.
  The IP address is displayed in one of the following colors:
  • Yellow: The IP address is unmanaged.
  • Blue: The IP address is excluded.
  • Pink: Indicates IP address conflicts.
  • GreyGray: The IP address is currently not available as a NIOS object.
• Type: The DHCP object type, such as DHCPRange or FixedAddress.
• Name: The object name. For example, if the IP address belongs to a host record, this field displays the hostname.
• Comment: The information you entered for the object.
• IPv4DHCPUtilization: The percentage of the total DHCP usage of a DHCP range. This is the percentage of the total number of fixed addresses, reservations, hosts, and active leases in the DHCP range divided by the total IP addresses in the range, excluding the number of addresses in the exclusion ranges. Note that only enabled objects are included in the calculation. It does not include abandoned addresses or leases.
• Site: The site to which the DHCP object belongs. This is one of the predefined extensible attributes. You can select the following additional columns for display:
• Static Addresses: Indicates whether the IP address is a static address.
• Dynamic Addresses: Indicates whether the IP address is a dynamically assigned address.
• Disabled: Indicates whether the object is disabled.
