Configure IP address management (IPAM)
NetScaler ADM IPAM allows you to auto-assign and release IP addresses in NetScaler ADM managed configurations. You can assign IPs from networks or IP ranges defined using the following IP providers:
- NetScaler ADM built-in IPAM provider.
- Infoblox IPAM solution.
You can use NetScaler ADM IPAM in:
- StyleBooks: Auto-Allocate IPs to virtual servers when you create configurations.
- API gateway: Auto-allocate an IP address to the API proxy.
You can also track the IP addresses in each network or the IP range managed by NetScaler ADM.
Add an external IP address provider
NetScaler ADM has a built-in IPAM provider to manage IPs and IP ranges. You can also use an external IP address provider to NetScaler ADM.
Important:
Before you begin, make sure that the following permissions are enabled in the external IP address provider:
- Ability to query networks that are present in the provider.
- Reserve an IP address in the network.
- Free an IP address from the network.
- Retrieve the used IP addresses from a network.
- Retrieve available IP addresses from a network.
Perform the following steps to add an external IPAM provider solution in NetScaler ADM:
-
Navigate to Settings > IPAM.
-
In Providers, click Add.
-
Specify the following details to add an IPAM provider:
-
Name - Specify the IP provider name to use in NetScaler ADM.
-
Vendor - Select an IPAM vendor from the list.
-
URL - Specify the URL of the IPAM solution that assigns IP addresses in an NetScaler ADM environment. Ensure to specify the URL in the following format:
https://<host name> <!--NeedCopy-->Example:
https://myinfoblox.example.com -
User Name - Specify the user name to log in to the IPAM solution.
-
Password - Specify the password to log in to the IPAM solution.
-
-
Click Add.
Infoblox DDI as an external provider
Currently, NetScaler ADM supports Infoblox DDI as an external provider.
You can use NetScaler ADM IPAM with the Infoblox provider to do the following actions:
- List IPAM networks
- Create, update, and delete IPAM networks
- Reserve and release an IP address from IPAM networks
Create an IPAM network
To create an NetScaler ADM IPAM network using the Infoblox provider, a network with the same CIDR IP range must exist on Infoblox.
When you create an IPAM network within NetScaler ADM, you’re only registering the use of Infoblox network within NetScaler ADM. ADM then works together with Infoblox to manage IP addresses allocated from the network. The InfoBlox network can continue to be used outside of NetScaler ADM.
Similarily, If you delete the NetScaler ADM IPAM network, NetScaler ADM de-registers the Infoblox network. This means that NetScaler ADM no longer interacts with Infoblox for IP address management in that network.
Infoblox DDI APIs
NetScaler ADM IPAM uses the following Infoblox APIs to perform the respective actions:
- (/network) - Lists all available Infoblox networks
- (/network?network={id}) - Retrieves details of a specific Infoblox network
- (/ipv4address) - Lists all IPs on an Infoblox network
- (/record:host) - Retrieves details of a specific IP address
- (/{IP}) - Reserves and frees IPs on an Infoblox network
Note:
- The Infoblox DNS, DHCP, and IP address management (DDI) server IP and port must be accessible from the public network so that the NetScaler ADM service can reach and connect to the Infoblox server.
- The Infoblox user account configured on NetScaler ADM must have the required permissions to use the Infoblox APIs.
For more information on the Infoblox APIs, see the Infoblox REST API reference guide available at Infoblox DDI.
Add a network
Add a network to use IPAM with NetScaler ADM managed configurations.
-
Navigate to Settings > IPAM.
-
Under Networks, click Add.
-
Specify the following details:
-
Network Name - Specify the network name to identify the network in NetScaler ADM.
-
Provider - Select the provider from the list.
This list displays the providers added in NetScaler ADM.
-
Network Type - Select IP range or CIDR from the list based on your requirement.
-
Network Value - Specify the network value.
Note:
NetScaler ADM IPAM supports only IPv4 addresses.
For IP range, specify the network value in the following format:
<first-IP-address>-<last-IP-address> <!--NeedCopy-->Example:
10.0.0.20-10.0.0.100 <!--NeedCopy-->For CIDR, specify the network value in the following format:
<IP-address>/<subnet-mask> <!--NeedCopy-->Example:
10.70.124.0/24 <!--NeedCopy-->
-
-
Click Create.
View allocated IP addresses
To view more details about allocated IP addresses from the IPAM network, do the following steps:
-
Navigate to Settings > IPAM.
-
Under the Networks tab, click View All Allocated IPs.
This pane displays IP address, provider name, provider vendor, and description. It also displays the resource details that reserved this IP address:
-
Module: Displays the NetScaler ADM module that reserved the IP address. For example, if StyleBooks reserved the IP address, this column displays StyleBooks as the module.
-
Resource Type: Displays the resource type in that module. For the StyleBooks module, only the configurations resource type uses the IPAM network. So, it displays Configurations under this column.
-
Resource ID: Displays the exact resource id with a link. Click this link to access the resource that is using the IP address. For the configuration resource type, it displays the configuration pack ID as the resource ID.
-
Note:
If you want to release the IP address, select the IP address that you want to release and click Release Allocated IPs.
