From switches, it downloads the MAC-Address Tables - which gets it the MAC Addresses. From routers, it downloads the ARP table, which gives it the ability to cross reference a given MAC Address to an IP address. From domain-controllers it downloads logfiles which have the usernames of folks logging in and what IP address they logged into. Use MAC Address Scanner (free trial) to scan subnets and create tables relating IP addresses to MAC addresses, DNSs, and manufacturer addresses. Search for MAC addresses on your network and more with the 60-plus network management and troubleshooting tools in SolarWinds Engineer’s Toolset. You can also look in your ARP cache on the local server. Use the command arp -A on the server and it will report back the IP address assigned to MAC addresses and whether they are dynamic or static. Use the command arp -A c: Mac.txt to store the results in a text file for import into other programs.
Doing a Network Reconnaissance helps network managers improve security by identifying weak devices that can be potentially breached. It can also allow managers to maintain a detailed and updated diagram of the network.
The network reconnaissance is basically identifying live hosts and scanning ports and services. When testing security or even hacking, port scanning becomes one of the most essential steps of a successful network exploration.
It basically helps identify open and vulnerable ports and protocols that are being used in the network. Port Scanning helps managers, testers, and hackers create a profile and gain intelligence about a target organization all while ensuring Access to critical Systems and services are managed correctly.
Live open ports can lead into the services running on hosts which can become a door into the organization. Running a port/services scan can make you aware of these weaknesses. With this information in hand, a network manager can secure a firewall by closing unnecessary ports and services.
The following is a list of the Best FREE IP Scanners for Port and Services, including a brief description, their features and official download site.
Here's a List of Best Free IP & Port Scanners of 2019:
There are a variety of scanners on the market which are usually online tools. But the best scanners are the ones that you run on your own devices since they allow more flexibility in the process.
1. SolarWinds Port Scanner
SolarWinds is one of the leading companies that create network and IT infrastructure monitoring software. The SolarWinds Port Scanner is one of the “Free Download” tools that allows you to scan an IP address range or hostname and generate lists of the open, closed and filtered ports on the target network.
The software is easy to use. To begin scanning you will only configure the scan profile. To do this you must enter the target information, such as IP range, hostnames. You can also configure it to look for layer 4 ports or services such as TCP or UDP ports.
Aside from the common IP and Port scanning, SolarWinds Port Scanner can also be configured to resolve hostname with specific DNS information and it can also find the MAC address to identify the OS version.
Common features?
- Uses multi-threading for less overhead and faster scanning.
- Schedule scans to ensure updated data.
- All scan profiles are configured in a single window with a command line.
- Save all scan profiles for future faster scanning.
- View all the IANA port name definitions right on the application.

2. Nmap
Nmap is considered the Swiss Army Knife of hackers (ethical and not) and pen-testers.
Solarwinds Mac Address Discovery Download Free
Nmap stands for Network Mapper and is one of the most popular port scanners. It is an open source tool that offers a great deal of flexibility and power when it comes to performing any kind of active network reconnaissance against a target. With Nmap you can craft packets and send them to a specific target and let the software analyze the response.
For beginners, Nmap can be a little bit intimidating because there are so many different scanning combinations that get you different results.
A very short list of what you can do with Nmap:
- Scan a target selection, such a single IP, a host-name, a range, etc.
- Scan a port selection, such as a single port or a range.
- Detect specific services and OSs.
- Perform NSE scripts.
- A really strong feature in Nmap is different “Port Scan Types”, such as TCP Connect, TCP SYN Scan. Below is a table with the most common TCP Scans Types that you can do in Nmap.
| Scan Type | Description |
| TCP Connect (-sT) | Full Three-way-handshake (SYN, SYN/ACK, ACK) |
| TCP SYN (sS) | Send SYN. RST/ACK response=not listening SYN/ACK=listening |
| TCP FIN (sF) | Send FIN, RST response=port close |
| TCP Xmas Tree (sX) | Send FIN, URG, PSH, RST response=port closed |
| TCP Null (sN) | No Flags. RST response=port closed |
| TCP ACK (PT) | Send ACK. Firewall test to verify packet filtering. |

With Advanced IP Scanner you can see a list of network devices with information such as IP, Port, Manufacturer, MAC Address, OS, etc.
This scanner finds all the devices in a targeted scan in a matter of seconds and provides easy access to their shared resources, either through HTTP, HTTPS, FTP or even shared folders.
Another cool feature of this tool is that it detects the RDPs or Radmin ports, and it will let you manage the device remotely right from the platform.
Common features:
- Easy access to network shares.
- Control devices via Radmin and RDP.
- Switch on/off computers remotely.
- Find the MAC addresses.

4. Angry IP Scanner
Angry IP Scanner (also called ipscan) is a free and open-source network scanner. The tool works on popular OSs, such as Windows, Mac OSX, and Linux. It was designed with simplicity in mind, the software is ultra-light, no installation is required (highly portable) and it is fairly easy to use.
At its most basic level, Angry IP Scanner will ping the target device/network to confirm that it is alive. It can also resolve hostnames, find the MAC address, and scan ports. You can extend the amount of information received about each target with the help of plugins.
Common features:
- Can scan private or a public range of IP addresses. Additionally, it can get the NetBIOS information of a device, detect web servers and customize openers.
- It is able to export the results in different formats such as TXT, CSV, XML, or IP-Port list files.
- For faster scanning, the tool uses the multi-threading approach.
- By default, the tool comes with common fetchers like Ping, Host-name, and Ports but you can add more fetchers with the help of plug-ins to see more information.
- The tool runs on the GUI, but you can use the CLI to call up different options on the software.

5. Free IP Scanner by Eusing
Eusing Software creates miscellaneous free applications for windows users. Among the most popular tools is the Free IP Scanner. This tool is a lightweight standalone scanner which can check a hundred devices per second. It is only supported by Windows OSs.
Free IP Scanner pings the IP (or range of IPs) to see who is alive. It can also translate the host-name to IP (or vice versa), find closed and open ports and get NetBIOS information. The last one can show details such as host-name, workgroup, active logged users, and the MAC address of the device. All the results obtained can be exported into a TXT file.
People like Free IP Scanner because it is simple, portable and easy to use. However, it cannot be extended with more functionality. Although the tool scans and finds ports, the entire layer 4 TCP/UDP information cannot be customized for deeper analysis.
Extra features:
- Fast scanning using multi-threaded technology.
- Free IP Scanner can scan multiple targets per second without consuming many resources.

6. NetCat
A fully versatile tool preferred by most hackers like NMAP above.
NetCat is not strictly an IP Scanner, it goes well beyond that. It is however a tiny Unix networking analyzer utility used by and against hackers for a large number of reasons.
It is tiny but powerful. NetCat is considered as a feature-rich networking tool used especially for debugging and investigation.
With NetCat you can create any kind of connection. It basically writes to and reads data from network connections using TCP or UDP. In other words, it can open TCP or UDP connections between two devices over any port.
The most common use for this tool is to set up reverse and bind shells, redirecting network traffic, port scanning and forwarding, debugging scripts, and service banner grabbing.
Some features?
- Connect to a remote system through any port or service.
- Banner Grabbing to identify the software that the target is using.
- Scan, listen and forward open ports.
