TeemIp IP Discovery is a solution that discovers active IPs on networks. While discovery activities are done by remote standalone collectors, discovery parameters are defined in TeemIp and discovery results are fed back and displayed within TeemIp.

Vocabulary: by “TeemIp solution” or “TeemIP”, it should be understood: TeemIp standalone or the iTop solution on top of which TeemIp as a module has been installed.


TeemIp IP Discovery provides a solution to TeemIp administrators to discover or scan their IP networks and to document within TeemIp the results of these discoveries and scans.

The solution is made of 2 components:

  • a discovery engine, called the IP Discovery Collector or the IP Discovery Application, that discovers IPs through pings, DNS reverse lookups and port scanning,
  • a TeemIp extension, called the IP Discovery Extension, that adapts TeemIp's standard data model to store the discovery outputs and enables communication between a TeemIp instance and the different discovery engines deployed on the network.

The IP Discovery collector is a standalone PHP software that relies on 3 different ways to discover its IP environment: ping, IP lookup and port scan, each of them being globally enabled or disabled per subnet. Several instances of that application can be installed on different servers. Should your network be compartmentalized by different firewalls, the different instances will allow you to bypass the restrictions imposed by the firewalls: limited pings or udp / tcp connections, DNS not available… Of course, you may install the collector on the server that hosts TeemIp but this is not necessary.

The IP Discovery extension is installed on a TeemIp instance. It can handle several IP Discovery applications.
