Many system administrators are in charge of remote networks. These networks can be distributed across several buildings as well as entire cities, regions, and countries.
IT managers need a tool that offers centralized network scanning as well as remote network monitoring so they can be notified if a problem occurs at a specific location.
PRTG is such a remote network scanning tool.
PRTG comes with different types of probes:
All data that remote probes send to the local probe or the hosted probe is secured with SSL/TLS. What's more: It only takes one click to set up a remote probe.
Paessler PRTG comes with a comprehensive auto-discovery feature that scans the private IP address range in the subnet of your PRTG server during installation. All devices that are available in this IP range are automatically added to your monitoring setup. Later, you can start the automatic search in other subnetworks as well.
With the IP scanner PRTG, you can see at a glance which devices are available in your LAN and start monitoring them right away.
The Ping v2 sensor sends an Internet Control Message Protocol (ICMP) echo request ("ping") from the probe system to the parent device to monitor its availability. It can show the following:
• Response time
• Packet loss
• Target status
• Minimum and maximum ping time
The Packet Sniffer sensor monitors the headers of data packets that pass a local network card using a built-in packet sniffer. You can choose from predefined channels. It can show the following and more:
The SNMP Traffic v2 sensor monitors bandwidth and traffic on a device. It can show the following:
See the PRTG Manual for a list of all available sensor types.

An IP address (internet protocol address) is a numerical representation that uniquely identifies a specific interface on the network. IP addresses are binary numbers that are typically expressed in decimal form (IPv4) or hexadecimal form (IPv6) to make reading and using them easier for human beings.
When you perform an IP address scan, you can see the devices that are available in your LAN within a specific IP address range. There are various tools for IP scans that use different scanning techniques.
There are many IP scanners available online that come as both freeware and paid software alike. When you compare different IP scanning tools, you should consider the following key features:
Yes, you can. Many network administrators run an IP address scan to discover hidden devices, that is, devices which are not officially part of the network. Shadow IT can be a huge risk factor with regards to network security, as unknown devices can be used as the basis for a network attack.
For home networks, we recommend basic open-source IP scanners, as PRTG is designed for companies. It is too powerful and often too complex for a private network at home. However, if you have the necessary skills, you can use our freeware edition that includes 100 PRTG sensors for monitoring your network at home.
Subnets are independent networks within an IP network. They use subnet masks to merge several successive IP addresses. A standard (RFC 950) is used to classify IP networks and subnets.
Upon installing PRTG, the software automatically performs a network scan of the subnet in which the PRTG server is located. Later, you can also perform this scan on other subnets in your LAN or in remote networks.
PRTG itself runs on Windows or you use our cloud-based PRTG product. However, as a cross-platform network monitoring tool, PRTG of course monitors Linux and Mac (macOS) systems as well.
On the Internet, you’ll also find free IP scanners such as Nmap, which was originally developed for Linux.
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive. On average, you need about 5-10 sensors per device or one sensor per switch port.
Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
Paessler PRTG is used by companies of all sizes. Sysadmins love PRTG because it makes their job a whole lot easier.
Bandwidth, servers, virtual environments, websites, VoIP services – PRTG keeps an eye on your entire network.
