The Ping sweep is a starting point of discovery. The SNMP system gives a lot of detail on all network devices and their current statuses. So, The Paessler Ping sweep works in concert with other protocols and utilities to map your network. The detection cycle continues while the monitoring software is active. This operation keeps the device register up to date and reorganizes the network map should any devices be removed, added, moved, or changed.
The system is implemented as a group of sensors. One of those is the Ping sensor. You have to pay if you need more sensors. Paessler offers a day free trial with unlimited sensors, so you can try out the system before paying for it.
Nmap is a free set of network system tools that execute from the command line. Zenmap is a GUI version of Nmap, and so it is easier to use. The scan format is dictated by a Profile that details search parameters.
The Zenmap GUI includes a number of set profiles, but you can create your own scan specification by editing an existing profile and saving it as a new version. Zenmap can perform scans with TCP as well as with Ping. The output of a scan will have a different layout depending on the profile.
You can get the IP addresses of active hosts, plus the hostname of each device. The scan can be changed to use TCP and show the open ports on each computer or router. The raw output of the underlying Nmap process is shown in the first tab of the interface. These details are difficult to read, but all subsequent tabs in the viewer interpret the data into easy-to-read records. One of the display formats is a Topology Mapper, which gives a graphical representation of all the links in your network.
This free software requires an IP address range as a parameter in order to start the sweep. It is possible to enter this rage in CIDR notation with an address and mask length combination, such as Alternatively, you can list IP Addresses in a file and pipe it into the command. As with any Linux command-line tool, you can pipe the output to a text file. Switches in the utility allow you to limit the sweep to just IPv4 or IPv6 addresses.
You can specify that only active hosts appear in the list, or you can ask to see all IP addresses in the range with inactive addresses labeled as unreachable. Another feature of the tool is the ability to link the output to DNS records. This displays the hostname for encountered IP addresses. This is an on-demand tool, but you could schedule runs by putting the command in a batch file and running it as a cron job.
The name of this tool tells you that ping lies at the core of its methodology. Network Pinger is a free tool that runs on Windows. The scanner requires an address range as input, and this can be expressed as a subnet in CIDR notation. The program pings each address in the sequence and reports on the responses. The interface shows the output of the serial ping as it progresses through the IP address range. Graphical displays in the dashboard show the response rate encountered with each ping execution.
A pie chart shows the percentages of addresses that could be reached and those that could not. The graphics in this ping sweep software are a really nice touch and they make it very easy to quickly sense the state of the network. Other functions of Network Pinger let you issue a ping to a single address.
A Traceroute function and a switch port mapper come built-in. Planning features include an IP calculator and statistical analysis reports. The Network Pinger contains many useful diagnostic tools that help you investigate the health of your network and find solutions to communication problems. The format of this free tool will appeal to longer-serving network administrators used to using commands such as Ping and Traceroute.
The latest version of this software is hping3. The tool is free to use. Ping is a function specified in the Internet Control Message Protocol. It also incorporates a Traceroute implementation. As a command-line utility, you can pipe the output to a file for analysis. Many commands are included in this tool, such as the ability to translate hostnames to IP addresses and test firewalls.
So, hping has a bit of a bad boy reputation. Angry IP Scanner is a very popular ping sweep tool frequently recommended by professionals in comment sections and message boards. Possibly one of the reasons for its popularity could be the format of its interface. The dashboard gives straightforward lists of results , similar to the no-nonsense presentation of command-line utilities that highly experienced techies prefer, combined with the window-based fonts of GUI systems that make the output easier to read.
This free network analysis tool can be installed on Windows, Linux, and Unix. It can check random IP addresses or a non-consecutive list given as an input file. The standard ping sweep output shows each IP address in the requested scan range, whether they were contactable or not. Missing addresses are indicated by the absence of a ping round trip time for that record. The absence of a hostname for a record should raise alarms if that IP address was contactable because either your DNS records are out of date or you have an intruder on the network.
The ping sweep results show whether each host has an open web host port , and if so, you will see the name of the web server system. Alternative functions of this tool include computer and router port scanning. Advanced IP Scanner can be installed on Windows 10 and it is free to use. You need to enter a scan IP address range before launching the sweep. You can also specify a list of IP addresses to check. The list has to originate in an XML file, which you first load it into a Favorites list.
The results list expands each record to reveal the shared folders available on every detected host. The headline record for each IP address shows the hostname for that node, its MAC address , and the manufacturer of that device. Once the utility has identified each live node on the network, you can access that computer and execute commands on it. You can also turn on computers on the network, put them into standby mode, or turn them off. A range of addresses to scan is required before launching the sweep.
The output from a scan can be written to CSV files. Import the data into a spreadsheet and compare the list of encountered IP addresses with the records from your DHCP server to spot abandoned IP addresses. This is a very simple tool, but its focus on the most important information that network administrators need from a ping scan explains its popularity.
The website for Advanced IP Scanner states that the tool has been downloaded by 30 million users. NetScan Tools comes in two versions. If you have an Excel file with IP addresses a vulnerability analyst like me has been bugging you about, paste it into the UI to ping sweep them from your Windows box find out which of them is still live. It can handle it. This is useful for sending evidence to security analysts or auditors. That takes you back to the initial screen.
Security analysts can use Pinginfoview too. When decommissioning hosts from Qualys or Tenable, I always run Pinginfoview on the list of allegedly dead systems first.
Including the first really expensive crisis of my IT career. I also use it when scanning new server builds. Unfortunately, modern Windows boxen don't respond to broadcast pings. Thus, your command will find Linux and other machines on your same subnet, but not the Windows boxes. I tested it in my lab, and found all my Linux machines happily telling me about their existence, but my super stealthified NOT! Windows boxes were silent. Thus, while the broadcast ping is a nifty alternative for some special edge cases targets on same subnet, don't care to find Windows boxes , I think the sweeper is the better way to go.
