But how can you tell if two IP addresses belong to same IP network? The answer is within something called a Subnet Mask. The rest of the IP address can then be used for computers and other hosts on the IP network. To really understand exactly how the Subnet Mask works you would have to study and learn about binary numbers and a few other more advanced topics.
Both an IP address and a Subnet Mask consists of four parts separated by periods. Each part of an IP address and a Subnet Mask can have a value between In its simplest form, each part of the Subnet Mask is either the number or the number 0 zero. If you wanted to tell somebody which IP network a computer is located within you would always tell them the first lowest numbered address on the IP network, which is the Network Address.
In the picture below, the first three parts of the IP address belongs to the IP network. This is determined by the Subnet Mask. The computer thus belongs to the IP network The fourth part. The next computer below belongs to the IP network It is using the host address 9 on the IP network, and its IP address is This computer belongs to IP network It has received host address 7 on the IP network, and its full IP address is What that means is that the three first parts of the IP address determine which IP network that the IP addresses belong to.
The last part of the IP address determines which unique address within that IP network that each individual computer has got. As we mentioned earlier, each part of an IP address can have a value between So the fourth part of the IP address permits for different addresses zero up to that can be used for computers, IP phones, routers, laptops, printers and other devices.
These type of devices are commonly referred to as hosts or clients. In a normal home network, those addresses are always more than enough to cover the devices that are connected to the network. Another term that is sometimes used is host which more commonly refers to computers and servers on the network. But none of these terms are really set in stone, and they are often used interchangeably.
We will scan a network with native OS commands, find which addresses were assigned dynamically, which statically, and test their connectivity. In the end, we will compare some free IPAM tools aka IP address scanning tools that can give you additional information.
To improve your IP addressing insights, even more, we will show you some tools that allow you to track IP addresses and even manage them. Operating Systems, like Windows and Linux, come with their own native simple networking set of tools.
The simplest way to get a quick list of IP addresses and their devices connected to your network is with those OS native commands found in the command line. With a list of the assigned IP address and their devices, you can easily find the devices that are causing the most problems.
On a Windows, the ipconfig command can be entered through the Command line. Now you know your subnet, which in this case is Now you need to find the rest of the IP address in your network. It provides a method for hosts on a LAN to communicate without knowing any address and create a cache of information. Finally, with some information, you can test connectivity. With this, you can learn some simple insights about delay and latency. From the list generated by the ARP command, you could ping all the live hosts.
Or you can go beyond and ping the entire subnet to find hosts not found by the ARP but that would be too much manual work…. Although having a list of devices and their allocated IP address will give you good insights, the information will not be enough when your network scales. As the network scales, problems will scale too.
An IP Address Scanner tool helps you with larger demands. A Ping Sweep tool lets you ping entire subnets and find live hosts just with one button. All of this data is also presented in the most visual and easy-to-read format. They also allow users to save all results and present them in detailed reports.
The SolarWinds Port Scanner tool is a great all around tool for scanning port DNS Addresses and IP's within the range that you specify, along with advanced abilities and capabilities that make it our 1 Choice on the list.
Download Free! This combination delivers all address-related functions that you will need in order to fully manage your network. The IP address manager is, in itself, a suite of utilities. This group of services includes an IP address scanner. This will discover all of the devices connected to your network and list the IP addresses allocated to them. The IP address tracker service in the bundle can produce a hierarchical view of your network, enabling you to identify subnets and the allocation of addresses to each.
DHCP management tools in the pack let you manage subnet address pools. The switch port mapper identifies each device by MAC address and switch port number.

An IP network is a communication network that uses Internet Protocol IP to send and receive messages between one or more computers. As one of the most commonly used global networks, an IP network is implemented in Internet networks, local area networks LAN and enterprise networks.
The Internet is the largest and best known IP network. Techopedia Explains IP Network Each host is assigned a unique logical IP address, which distinguishes it from other nodes and helps initiate data communication with other hosts.
