Use the **Reserve IP address** workflow to reserve a specified IPv4 or IPv6 address, create a host record, or create a DNS record for a host in NIOS. The workflow creates NIOS records with the specified static IP addresses and allows you to assign extensible attributes to the records you create.

NIOS objects you can create with this workflow are:

- Host records
- A/AAAA records with or without associated PTR records
- CNAME records related to the created A/AAAA records
- Fixed address or reservation records

To reserve an IP address:

1. Log in to the *VMware Aria Automation Cloud Services Console*.
2. On the **Services** tab, click **Orchestrator**.
3. In the **Dashboard** panel, expand **Library** and click **Workflows**.  
The **Workflows** folder and its contents are displayed.
4. Expand **Library** > **Infoblox**, and select **Reserve IP address**.
5. In the top-level menu of the workflow panel, click **Run**.  
The **Reserve IP address** panel is displayed.
6. On the <span style="color: #000000">**Connection**</span> tab, click **Connection to the IPAM server** and select the IPAM connection as follows:
  1. In the **Select InfobloxIPAM:IPAMConnection** dialog, expand **Infoblox IPAM** and select the IPAM connection.
  2. Click **Select**.
7. On the **IP Address** tab, configure the following parameters:
  1. **IPv4/IPv6 address**: specify the IPv4 or IPv6 address to be reserved.
  2. **Network view**: choose the network view where the IP address resides.
8. On the **Common parameters** tab, define which NIOS object to create:
  - **Create host record?**: This option is enabled by default. Configure the following parameters:
    - **Host name (FQDN)**: specify the host name to use in FQDN format.
    - **Enable DNS for the created host Record**: select the option if you want to enable DNS, and then choose the **DNS view** in which the record must reside.
    - **Enable DHCP for the created host record**: select the option if you want to enable DHCP in the host record.
    - **MAC address or DUID** (required when you enable DHCP for the host record): specify the MAC address or DUID for the host record.
    - **List of aliases for the host record in FQDN format**: The aliases to use for the host record.
    - **Comment**: add a description of the host record.
  - **Create DNS record?**: this option is visible only if **Create host record?** is disabled. Select it and configure the following parameters:
    - **Select DNS record to create**: choose whether to create an **A/AAAA** record or **A/AAAA/PTR** record.
    - **Host name (FQDN)**: specify the host name to use in FQDN format.
    - **DNS view**: choose the view in which the record must reside.
    - **List of aliases for CNAME records related to the created A/AAAA record in FQDN format**<span style="color: #000000">: you can associate CNAME records with the created A/AAAA record by setting aliases in FQDN format. For</span> more information, see the *Managing CNAME Records* section in the *[Infoblox NIOS Documentation](https://docs.infoblox.com/space/NIOS/35400616/NIOS)*.
  - **Create fixed address?**: this option is visible only if **Create host record?** is disabled. Select **Create fixed address?** and configure the following parameters:
    - **Select fixed address or reservation to create**: choose **Fixed address** or **Reservation**.
    - **Name of the fixed address or reservation**: specify a name for the address or reservation.
    - **IPv4 address of the Microsoft DHCP server (applicable for IPv4 fixed address only)**: specify the IP address.
    - **MAC address or DUID**: specify the MAC address or DUID if you are creating a fixed address.
    - **Comment**: add a description of the fixed address.
9. On the **Number of attributes** tab, to assign extensible attributes to the network:
  1. In the **Number of specified extensible attributes** drop-down list, choose a number.  
According to the number you chose, additional tabs are added to define the extensible attributes. For example, if you specify **2**, **Extensible attribute #1** and **Extensible attribute #2** tabs are added.
  2. On each **Extensible attribute #<*****n*****>** tab define the extensible attributes you want to add to the network object:
    1. Click **Definition of the extensible attribute #<n>**.
    2. In the **Select Infoblox IPAM:IPAM Extensible Attribute Definition** window, expand the IPAM connection ID > **Extensible Attributes**, and select the extensible attributes.
    3. Click the **Select** button.
    4. In the **Value of the extensible attribute #<*****n*****>** field, specify a value.
10. On the **Restart DHCP service** tab, select **Perform restart of DHCP service if needed**.
11. Click **Run**.
