Best IP Monitoring Tools

You need to use automated tools in order to keep a check on your network’s smooth operations. Although there are a number of command-line utilities that you could use to perform spot checks on the network’s statuses, automated tools do the job better.

An automated IP monitoring tool will watch the network so you can get on with other tasks. If any problems arise, the IP monitoring software will send you an alert. You don’t need to perform IP monitoring yourself; you just need to know when things stop being OK.

IP monitoring tasks

The job of IP monitoring encompasses a lot of specialist tasks.

IP monitoring is a very broad term and refers to the successful management of any TCP/IP-based network. This is because the “IP” part of TCP/IP gets its name from the Internet Protocol and also refers to the protocol family that groups around it at the Network Layer of the protocol stack.

IP monitoring tool categories

The field of IP monitoring software can be divided into three main categories:

  • IP address management
  • Network performance monitors
  • Ping-based tools

Here are further details about each of these categories:

IP address management

An IP address manager is also called an IPAM. You need to be sure that all of your network devices have correct IP addresses assigned to them. You don’t want several devices using the same IP address. You also need to be sure that you are using your IP address pool efficiently so that you don’t run out of available addresses.

Beyond the mechanics of IP address management, you also need to be sure that your entire address space, i.e. the network, is functioning properly. A DHCP server, which allocates IP addresses and DNS servers, which cross-reference IP addresses to hostnames, needs to be kept updated with the results of an IP address scan. So, DNS servers, DHCP servers, and IPAMs are often grouped together and called DDI.

Network performance monitors

Controlling the performance of a network also comes under the category of IP monitoring. Network performance monitors check on the health of the devices that connect links together. They track down and log all connected devices and watch out for any failures that might occur.

By deploying an alerting mechanism, automated network performance monitors can free up IT staff for other tasks while performance is at an acceptable level.

Ping-based tools

The Internet Protocol has a related standard called the Internet Control Message Protocol (ICMP) which provides one of the most fundamental services used in network monitoring: Ping. Many brands of network supervision software are truly IP monitors because they are built around the execution of the Ping command.

Ping can be used as a basic form of IP address manager, called an IP scanner, it can also be used to check on the speed of a connection.

You can use Ping yourself to get network performance data. However, to be truly effective, you would need to issue Ping over and over again to each and every point on your network simultaneously. Automated IP monitoring tools can perform that task more effectively than you can.

The service is charged for by subscription and you can get a 14-day free trial of all but the Enterprise plan.

IP Monitoring FAQs

What is IP address monitoring?

IP monitoring is a test for the availability of devices connected to a network or to remote systems that are contactable across the internet. The most frequently used tool for this task is Ping.

How does IP monitoring work?

IP monitoring sends out a connection request to a specific IP address and examines the response. This service can be used for uptime monitoring of websites. The technique can also be used to test the availability of devices connected to a private network by working through a range of IP addresses and recording which addresses send back a response, which indicates that the address is in use.

How do I monitor a device by IP address?

IP monitoring is usually limited to availability tests. Once a packet sent to a specific IP address gets a response, the monitoring system can note that there is a device on the network using that address. The monitoring tool will then use other monitoring techniques, such as the Simple Network Management Protocol to examine details of that device’s activities.
