IP Ranges

IP Ranges

IP ranges objects in TeemIp represent sets of contiguous IP addresses that belong to a given subnet. Typically, IP ranges are used to reserved IP space for an application (like DHCP) or to group devices that share the same function (like printers).

IP Range Properties

Name	Type	Mandatory?
General Information
Organization	Foreign key to a(n) Organization	Yes
Usage	Foreign key to a(n) IP Range usage	No
DHCP Range	Yes or No	Yes
Note	Multiline character string	No
Requestor	Foreign key to a(n) Person	No
Allocation date	Date (year-month-day)	No
IP Information
Subnet	Foreign key to a(n) Subnet	Yes
Name	Alphanumeric string	Yes
First IP of Range	IPv4 or IPv6 Address	Yes
Last IP of Range	IPv4 or IPv6 Address	Yes

IP Range Usages are typology elements defined in the Data Administration module. One set of IP Range Usages needs to be defined per organization.

Tabs

Tab	Description
Global Settings	Settings defined for the IP Range's organization and values used at creation time
Contacts	All the contacts for this IP Object
Documents	All the documents linked to this IP Object
DHCP Servers *	List of all DHCP servers attached to the range
DHCP Options *	List of all DHCP options attached to the range
Notifications	List of related notifications - Present if a notification trigger exists for that class
Registered IPs	IP addresses belonging to the IP range
Activity panel	History of all changes made to the IP range

(*) These tabs are only visible on ranges that are flagged as DHCP ones.

Each server listed in the DHCP Servers tab may have a specific role: Active, Primary, Secundary, Single or Split Scope. CIs listed in that tab can be if class NAS, Network Device, Server or Virtual Machine.
The DHCP Options tab is actually managed by the “TeemIp DHCP Management” extension where Pool Options are managed.

Listing IP Ranges

The IP Ranges shortcuts under the IP Management menu display all the IPv4 or IPv6 Ranges of the selected organization or all IPv4 or IPv6 ranges registered in the application if no organization is selected.

The “Registered IPs” column gives the percentage of the IP Range that is already consumed by all the IPs within the range.

The Search tab will shorten the list according to the filtering elements you'll define in it.

Creating a new IP Range

From the listing view or from any create action of a subnet range badge, click on the to display the creation form.

An implicit but intuitive set of rules must be followed when an IP range is created:

A range must be fully contained within the subnet it belongs to,
Its name must be unique within the subnet,
It cannot overlap with other IP ranges of the same subnet,
It cannot contain another IP range

Display an IP Range

From the list of ranges, select the one you'd like to consider. DHCP ranges may be associated to DHCP servers (of class NAS, Network Device, Server or Virtual Machine):

When linking a server to a DHCP range, you may specify its role: Active, Primary, Secundary, Single or Split Scope.

Modify an IP Range

From the detailed view of an IP Range, click on the button.

The parameters that can be changed here are: Name, First and Last IPs, Usage, DHCP range, Note, Requestor as well as the lists of Contacts and Documents attached to the IP Range.

Navigating between adjacent Ranges

TeemIp provides an easy and efficient way to navigate between adjacent ranges. If the action is enabled, the left and rights arrows of the object menu will bring you to the previous or next registered range in TeemIp. This action is driven by default parameters that can be overwritten in the configuration file.

	'teemip-ip-mgmt' => array (
		...
		'range_navigation' => array (
		  'enabled' => true,
		  'within_subnet_only' => false,
		),
                ...
        ),

Parameter	Description
enabled	Enable or disable the function
within_subnet_only	Limit the navigation to the subnet that the range belongs to or not

Other Actions

Next to standard actions, a set of specific actions can be applied to IP Ranges. These can be found in the Other Actions menu available from the details page.

These specific actions are described in below chapters.

List & Pick IPs

The List & Pick IPs action simply lists, in numerical order, all the IP addresses hosted within an IP Range. It lists as well the free IP addresses and provides the possibility to directly register them.

The list is limited to 4096 IPs. Should the subnet contain more IPs, then a preliminary screen asks the user to shorten subnet boundaries so that less than 4096 IPs are displayed.

All free IPs can be created by clicking the appropriate button. This will open a popup window where all IP details can be registered. If you don’t wish to proceed, the top right menus will lead you to your next page.

The highlighted status (like Unassigned, here) and the PING, LOOKUP or SCAN labels are set by the IP discovery process. Please, refer to the TeemIp IP Discovery extension for a detailed view on that subject.

CSV Export IPs

This function exports in a text format all IPs of a given subnet: IPs that are registered (regardless their status: allocated, reserved, released or unassigned) and IPs that are not registered and that don’t exit as an object in TeemIp data base.
