A ping sweep is a simple method to get a list of live IP addresses on your network. It only returns results for hosts that are turned on and active. So, this is a great audit tool that enables you to recover abandoned addresses in a DHCP environment.
We’ve gathered some great ping sweep tools and software on the market. Here’s our list of the 10 best ping sweep tools available today.
- SolarWinds Ping Sweep (FREE TRIAL)
- Network Pinger
- Angry IP Scanner
- Advanced IP Scanner
- NetScan Tools Basic Edition
- Mitec Network Scanner
In the next section, you can read more details about each tool.
SolarWinds is a leading network software producer and the Ping Sweep tool is part of one of the company’s network management packages. The Engineer’s Toolset contains more than 60 tools for monitoring and managing a network and this pack includes Ping Sweep.
The interface is very straightforward; just enter a range of IP address addresses to scan. You can specify a broad range if you are unsure of the total scope of addresses in use. By feeding in a text file with a list of IP addresses, you can extract a list of all the IP Addresses that have been allocated from a DHCP server.
Once you launch the search, the tool lists all of the active IP addresses it finds on the network. The results of the sweep can be exported as a text file, a CSV file, XML file, or an HTML page. With this, you can import the list into a spreadsheet and compare it to the list from the DHCP server. Subtracting the Ping Sweep results from your DHCP results will give you a list of abandoned IP addresses that you can restore to the pool of available addresses in your DHCP server.
The Ping Sweep results show the time it took for each host to respond. The response time highlights traffic bottlenecks on your network or where individual pieces of equipment are experiencing performance problems. You also get the hostname of each detected device. Exporting the IP addresses and host names enables you to compare the current list of hostnames to records from your DNS server and make sure the server’s report reflects the actual address status of your network.
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 software can be installed on Linux, Mac OS, Unix, and Windows.
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 host name of each device. The scan can be changed to used 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.
Zenmap results can be stored as XML files.
Fping is a command line tool for Linux systems. 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 192.168.1.0/24. Alternatively, you can list IP Addresses in a file and pipe it into the command. You can get a report on IP address allocation in text format from your DHCP server and feed that into fping. 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. If the DNS entry looks wrong or if a record is missing a hostname, you can spot DNS problems.
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.
Hping is a command line utility, so it doesn’t have the sophistication of GUI-based interfaces that have become common in modern network management tools. 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. Hping3 installs on Linux, Unix, and Mac OS and Windows.
Ping is a function specified in the Internet Control Message Protocol. It operates at the Internet Layer of the TCP/IP stack.It doesn’t have port visibility, an addressing system employed in the higher Transport Layer. Hping sends out serial ping requests to each IP address in a given range. TCP and UDP messaging capabilities let you test the ports on your computers and routers. 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 host names to IP addresses and test firewalls.
Hping is of interest to hackers because it can help gather information on a target computer and be used to launch a denial of service attack. So, hping has a bit of a bad boy reputation. However, this doesn’t mean that you shouldn’t use it to discover information about your own network and communication devices.
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. The scanner sweeps a given range of IP addresses that can be in CIDR notation format. It can check random IP addresses or a non-consecutive list given as an input file. Output can be directed to CSV, TXT, XML or IP-Port format files.
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.
A DNS resolution function shows the hostname for a requested IP address if it can find it. The absence of a host name 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. You can get the MAC address of each host displayed for its IP address ping record.
The presence of host name resolution and port activity details shows the ping sweep function doesn’t just employ ICMP ping commands. 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 host name 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 address.
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. One of these is a paid version called NetScan Tools Pro, and the other is a free system called NetScan Tools Basic. The ad-supported Basic edition has a reduced set of features compared to the Pro package. The Ping Sweep tool is included in the Basic Edition.
The ping sweep utility, called Ping Scan, requires an IP address range as inputs to the search. Once the sweep is launched, the tool attempts to contact each of the addresses in the given range. The results for each IP address show the response time from the ping round trip and a status comment. You can exclude non-responding addresses and include the hostname for each address in the results.
The absence of a host name for an IP address that was contacted points to a possible problem with the networks DNS server. Another tool in the NetScan Tools Basic package specifically queries the system DNS to check for errors. You can print or copy the sweep results and save them to a file.
The Pro edition of NetScan Tools has more utilities. You can buy it for $249 for one license and up to $2,255 for five licenses. Both NetScan Tools Basic and NetScan Tools Pro are designed to run on Windows 7, 8, and 10.
Pinkie is a handy free tool with a lot of other utilities in addition to its Ping Sweep. This set of tools is only available for Windows. You can download Pinkie here.
Start by specifying a starting address and the number of hosts that should be scanned. You can choose to only include live hosts in the results. In that case the sweep will continue either until the number of active IP addresses has been encountered or until all of the network has been scanned. If you don’t specify the live host requirement, the tool will include abandoned addresses in the sweep host count.
The tool works quickly and lists each encountered live IP address, or every address in sequence until the maximum number of hosts has been reached. Each record contains the host name and the response time, which is the ping round trip time.
You can save the results to a file by copying it to the clipboard. You then paste the records out of the clipboard into a file. This enables you to reconcile the results with a record extract from your DHCP server. The Pinkie bundle includes a straightforward Ping, a Traceroute, a port scanner, and a subnet calculator. The utility also includes a TFTP server.
The Mitec Network Scanner is a system administration tool that includes a ping sweep utility. The free tool can be installed on Windows 7, 8, and 10 and Windows Server 2008, 2008 R2, 2012, 2012 R2 and 2016.
The ping sweep feature forms the heart of the Network Scanner. It gathers a list of live IP addresses within a given range. For each encountered address, you see that device’s MAC address, hostname, and response time, which represents the ping round trip time.
Other features in the tool let you explore each discovered device to deeper detail. This includes an inventory of the ports on the device and the manufacturer of that piece of equipment.
The Network Scanner is a useful tool that includes a Whois function and DNS resolution.
Ping is a function of the Internet Control Message Protocol. It is available as a command line utility on any computer connected to a network no matter what the operating system. Ping is so universal that it is a basic component of any network administrator’s toolkit.
Command line utilities are not so popular these days. Many GUI adaptations of ping have been created by both individuals and software houses. Ping has a list of switches that alter its behavior. Each run of ping can only contact one address. The concept of a ping sweep can be implemented by a simple script that works through a list of addresses and issues the ping command for each.
The underlying functions of the software in this list are all variations of a script with a recursive loop, calling ping over and over again as it combs through the addresses in a given list.
Despite being a very old and very simple tool, ping is very powerful. For example, simply reporting on a response from an address means that ping can be manipulated to detect IP addresses that are actually in use on a network. This is an essential requirement of any IP address management system.
The response time output field of ping is very useful. In a ping sweep, a troubled device shows a very long response time. If you test all of the devices on your network through a ping sweep, most devices will respond within a very close range of times. One or two high numbers in that Response Time column will instantly show when a device is overloaded or damaged.
Although ping is a straightforward and free utility, the developers who create variants such as a ping sweep deserve respect. The addition of graphical outputs, such a response time line graphs, are also nice to see.
Other simple network tools
Traceroute is a very similar networking tool to ping, but Traceroute uses UDP packets. Traceroute sends out a series of packets with the “time to live” field steadily increasing.
The ICMP protocol, which ping uses, includes an error messaging process that reports back on failure, giving the address of the device that reported the error. Traceroute uses this facility to log the addresses of all of the devices in the path. A combination of ping and Traceroute enables you to build a map of your network. Some of the ping sweep utilities listed in this guide use this exact combination to provide graphical representations of the network under investigation.
Port mapping tools are also very useful. These use both TCP and UDP to check whether each port on a device is open.
Ping operates at the Internet Layer of the TCP/IP protocol stack, so it has no concept of port numbers. If you get a ping sweep tool that reports on the ports on a device as well as the device’s status, then that ping sweep has been performed with a combination of protocols that add to the small amount of information available to ping.
Ping sweep alternatives
A ping sweep utility can also be called an IP address tracker. Both of these types of software perform the same task: identify all of the IP addresses in use on a network. If you need more detailed information on IP address usage on your network, step up to a more complex tool. In this instance, the tool you seek is an IP address manager. The SolarWinds IP Address Manager is one example.
Ping sweep operations
Check out the ping sweep tools in this list. A ping sweep is more appropriate for a small network. As your network grows, you may find that the manual steps needed to analyze data from a ping sweep takes up too much time. If this is the case, then your network is probably too big for a ping sweep to be a time-saving utility, and you should investigate IP address managers instead.
