How do you use IP Scanner?
When authenticating the (MAC address of an internet user against predefined combinations of MAC addresses and IP addresses, the network-based MAC address scan fails. This is because the network traffic from the internet does not contain the actual MAC address of the user. The IP/MAC Address Management tool is a database tool designed to maintain IPv4/MAC address associations found using the NetScanner tool, SNMP tool, ARP Scan tool, and the Network Shares - SMB tool. IP/MAC address associations are gathered from the Ping Scanner following a ping sweep.
IP Scanner is a cloud tool that scans your local network and returns a sortable list of the devices it discovers. Devices can be filtered, searched, and exported to CSV. By default, it detects and scans a local subnet, though you can also define a custom IP range.
What details does the IP Scanner return?
The IP Scanner lists each device’s hostname, IP address, vendor, OS, MAC address, description, open ports, and if it’s up or down. The kind of data returned depends on the type of device being scanned.

Add agents to your servers and workstations to get more detailed information like CPU, storage, memory, and network adapter details. You can even see the tickets for each device.
How do you set up the IP Scanner?
IP Scanner uses a small downloadable scan agent to give it access to your local network. To get started click Download to install the scan agent. A wizard will quickly step you through installation.
A browser page will launch and prompt you to scan the detected IP range. You can customize the IP range that will be scanned if the default range doesn’t discover all of your devices.
When you’re ready to take your device information collection to the next level, go ahead and click the Agent Download button, then choose Download a Collection Agent. You can get the agent for both Windows and Mac. Then you’ll just copy the agent installer to each device you want to track. Want to save even more time? You can use Group Policy (or whatever 3rd party software distribution service you prefer) to deploy the agent in your network.
This tutorial marks the beginning of a series of network security and penetration testing articles that I will be posting on this website.
The purpose of this article is to describe how to perform a simple NMAP scan of an IP range/subnet on a network. There are hundreds of scan options with NMAP but I will start with the most useful one which is to scan a range of IP addresses together with some other extra options.
NOTE: For a more comprehensive NMAP Tutorial with all popular and useful commands you can download this Nmap Cheat Sheet PDF here.

One of my responsibilities in the company I work is to perform security assessments and penetration testing on the external and internal systems of the enterprise. The tool that I use in almost all penetration testing engagements is the famous NMAP scanner (short for Network Mapper tool).
In a penetration testing project you need first to “map” and identify as much information about your targets so that to plan your next steps. This is the reconnaissance phase of a security test.
NMAP is an excellent utility to help you in the reconnaissance phase since you can collect information such as:
- What IP addresses are live on the network (i.e what IPs have hosts running on them).
- What ports are open on these IP addresses.
- What services are running on the open ports (together with service versions etc).
- What operating systems are running on the identified IP addresses.
- Find well known vulnerabilities on the scanned systems (using NSE scripts).
- Verify firewall rules.
- And much more
Now let’s go ahead and see several nmap options to scan multiple IP addresses in a network.
Simple NMAP scan of IP range
The default scan of nmap is to run the command and specify the IP address(es) without any other options. In this default scan, nmap will run a TCP SYN connection scan to 1000 of the most common ports as well as an icmp echo request to determine if a host is up.
There are four ways to scan multiple IP addresses:
1) Specify IPs one-by-one separated by space
nmap 192.168.10.1 192.168.10.111 192.168.10.222

2) Specify IPs in consecutive range

Nmap done: 131 IP addresses (2 hosts up) scanned in 6.52 seconds
3) Specify a scan range of IPs using a wildcard
nmap 192.168.10.*
4) Specify a scan range of IPs using a subnet notation
nmap 192.168.10.0/24
Scan all ports of an IP range
The simple default scan above will check the 1000 most well known ports for each IP address. What if you want to scan ALL ports of the IP range under scope. Let’s see how to run this:
Assume we want to find all open ports in class C subnet 192.168.10.0/24
1st way
nmap -p- 192.168.10.0/24
2nd way
nmap -p 1-65535 192.168.10.0/24
Discover Live IPs in a subnet
This is a “ping scan” to identify live hosts in the specified range.
This scan option uses a combination of scan techniques to identify live hosts, such as sending an icmp echo request, TCP SYN packets to ports 80 and 443, timestamp requests, arp requests etc.
nmap -sP 192.168.10.0/24
Detect OS and Services Running in a subnet
Scan Mac Addresses On Network
Now we will see how to scan a range of IPs and detect what Operating System and Services (versions) are running on live hosts.
