Networks


 

         

Viewing the network list

In the Network 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 the "Create new network" in the action menu of the Inspector. 

A wizard dialog appears to guide users through the process. 

         

 

  1. Fill in the network along with the subnet mask.
  2. When creating a DHCP network, the check box "Create a DHCP network" should be checked. (See below for details.) 
  3. Specify if the network should be locked or if auto assignment of IP addresses should be allowed.
  4. Click Next.

Step 2 (optional)

If the "Create a DHCP network" box is checked in Step 1, the following dialog is presented:

 

         

 

Step 3

 

         

 

  1. Fill in the title and description. 
  2. Fill in to any custom fields to be defined in the system.
  3. Click Next.

Step 4

 

        

 

Users are presented with summary information about the network before it is created.

  1. To open the range after it has been created, check the "Open range after creating" box.
  2. Optionally, add a save comment for audit trail purposes.
  3. Click Finish. 

The new IP address range or DHCP scope will be created.

Additional actions

After selecting a network in the list, the available actions are shown in the Inspector on the right.

IP Addresses


Viewing a network

To open a network, double click on a network or select the network and clicki 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

ColumnDescription
AddressAn IP address within the IP address range
State

For IP address ranges, the possible states for IP addresses are

  • Free
  • Assigned
  • Claimed
Last known MAC AddressThe last known MAC address associated with the IP address. (Obtained through discovery.)
DNS namesA 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:
    • There is an A record but the PTR record is missing.
    • There is a PTR record but the A record is missing.
    • The data section in the PTR record does not correspond to the name of the A record.
Last seenThe date and time which the IP address was last seen during discovery.
DeviceIf 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.

ColumnDescription
Pool color indicator
  • Blue: IP address is in a DHCP pool
  • Green: IP address has a DHCP reservation
  • Red: IP address is in an DHCP exclusion range
  • Grey: IP address is in static part of DHCP scope
State

For DHCP scopes, the possible states for IP addresses are

  • Free
  • Assigned
  • Claimed
  • Leases
  • Reserved
Lease nameThe name of the DHCP lease
Lease descriptionThe description of the DHCP lease
Lease client identifierThe client identifier of the DHCP lease
Lease expiresThe expiration time of the DHCP lease
DDNS HostnameThe 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.

The following dialog allows users to specify all the details for the reservation. 

 

         

 

Adding a DNS host

To add a DNS host for a specific IP address within a IP address range or a scope

  1. Select the IP address in the list
  2. In the Related DNS data section of the Inspector, click on the "Add" button
  3. A dialog will be displayed which allows for adding the record
  4. Specify a record name.
  5. Specify a zone name. (Typing in the zone name field will start generating a list of potential zone names with autocomplete.) 
  6. Fill in other information.
  7. Click "Create" to create the new record.

Additional actions

After selecting an IP address in the list, the available actions are shown in the Inspector on the right.

Find next free IP addressSelects the next free IP address.
Create new DNS recordDisplays a dialog where DNS records associated with the IP address can be created.
Claim IP addressClaims the IP address.
Ping IP addressPings the IP address. See Pinging an IP address.
View historyOpens a dialog which shows the history for the selected IP address.
Import IP address dataOpens an import wizard where networks can be imported.


Pinging an IP address

An IP address or multiple IP addresses in the list can be pinged by: select them and then click on the "Ping IP address" task in the Inspector.

An indicator is shown during the ping. Afterwards a green or red indicator on the left of the IP address indicates a successful or unsuccessful ping.
