Networks
Viewing the network list
In the Networks section of the Web Application, users are presented with a list of all networks in the system that they have access to view.
The networks lists shows all IP address ranges and scopes in the system (depending on what is selected in the Filtering sidebar). The visible columns can be configured by clicking on the “Configure columns” icon above the list.
The utilization of ranges and DHCP scopes is shown in a column called Utilization showing each network’s utilization.
Creating a network
Step 1
Click on the Create button above the list, or click on on the top or in the Inspector.
A wizard dialog appears to guide users through the process.
Fill in the network along with the subnet mask.
When creating a DHCP network, the check box Create a DHCP network should be checked. (See below for details.)
Specify if network and broadcast addresses should be reserved.
Click Next.
Step 2 (optional)
If the Create a DHCP network box was checked in Step 1, the following dialog is presented:
Step 3
Fill in the Title and Description.
Fill in to any custom fields to be defined in the system.
Click Next.
Step 4
Users are presented with summary information about the network before it is created.
To open the range after it has been created, check the Open range after creating box.
Optionally, add a save comment for audit trail purposes.
Click Finish.
The new IP address range or DHCP scope will be created.

DHCP information
After selecting a DHCP scope in the list, information on DHCP pools can be viewed in the inspector on the right.
The name of the authoritative DHCP servers are shown along with pools and exclusions defined in the scope.
In the case of split and failover DHCP scopes, both authoritative servers are shown and the respective pools and exclusions.
Changing between address spaces
If there are more than one address space defined, it is possible to change between address spaces by going to
and select a different address space to activate.IP Addresses
Viewing a network
To open a network, double click on a network or select the network and click on Open.
An example of a network which is an IP address range can be seen below.
Note
Each IP address in a network can have different states. It depends on whether it is an IP address network or a DHCP scope.
Column descriptions
IP Address Ranges
Column |
Description |
---|---|
Address |
An IP address within the IP address range. |
State |
For IP address ranges, the possible states for IP addresses are:
|
Last known MAC Address |
The last known MAC address associated with the IP address. (Obtained through discovery.) |
DNS names |
A list of DNS hostnames associated with the IP address. |
PTR status |
Shows the status of the Address (A) record and Pointer (PTR) record mappings. This column can have three values: Empty. There are no DNS records for the host. It is also empty if a PTR record exists where the domain in the data section of the PTR record is not managed by the system. OK. There is a match between the A and the corresponding PTR record(s). Verify. There is no match between the A and the PTR records for the host. The most common reasons are:
|
Last seen |
The date and time which the IP address was last seen during discovery. |
Device |
If the IP address is associated with a device, the name of the device is shown. |
DHCP Scopes
Note
The table below shows only additional columns shown for DHCP scopes. Shared columns are described in the table above.
Column |
Description |
---|---|
Pool color indicator |
|
State |
For DHCP scopes, the possible states for IP addresses are
|
Lease name |
The name of the DHCP lease |
Lease description |
The description of the DHCP lease |
Lease client identifier |
The client identifier of the DHCP lease |
Lease expires |
The expiration time of the DHCP lease |
DDNS hostname |
The DDNS hostname associated with the DHCP lease |
An example of a network which is a DHCP scope:
Creating a DHCP reservation
Inside a DHCP scope, select a specific IP address in the list, and then click on the “Reserve” button above the list.
Adding a DNS host
To add a DNS host for a specific IP address within a IP address range or a scope:
Select the IP address in the list
In the Related DNS data section of the Inspector, click on the + button
A dialog will be displayed which allows for adding the record
Specify a record name.
Specify a zone name. (Typing in the zone name field will start generating a list of potential zone names with autocomplete.)
Fill in other information.
Click Create to create the new record.
