I like this tool because it’s updated often, runs on Windows 10 and has a 32-bit and 64-bit version. ANGRY IP SCANNER ANDROID FREELet’s start off with a free tool for Windows PCs called SoftPerfect Network Scanner. If you never connect to your computer remotely, then having remote desktop enabled is just a security risk. When looking at open ports for a computer or device, you can easily see whether remote desktop is enabled, whether an FTP or HTTP server is running and whether file sharing is enabled or not. Anyone who connects to your network via cable or wireless could then easily search for shared folders and copy that data to their computer. For example, you may find folders that are being shared on your network by accident. But is it really? Well, to be honest, it’s actually rather simple.Though it’s a bit technical, the information can help you make your network more secure. What can be complex, in most real-life situations, is keeping track of IP address usage. The single most important thing about IP addresses is that each one must be unique within a network. ANGRY IP SCANNER ANDROID PORTABLE#ANGRY IP SCAN PORTABLE SOFTWARE#Ī ton of such tools are available as open-source software but many of these run on open-source operating systems such as Linux.įor an up-to-date picture of which IP addresses are in use and which are free, nothing beats an IP scanner.Īnd while most administrators use some sort of IP address management tool-which, sometimes, can be as simple as a text file with IP addresses and computer and device names, they have no real control over what actually gets plugged into the network. If you’d rather use tools that can run on Windows, we’ve compiled a list of the best IP scanners for Windows.īefore we reveal what the best tools are we’ll briefly sidetrack and have an in-depth look at IP addressing. We’ll discuss IP address allocation and management and compare static and dynamic addressing. Then, we’ll have a look at the different types of IP address tools that are available. Finally, we’ll be ready for the big reveal and have a look at some of the best IP scanners for Windows. We’ll introduce each tool and present its main features. IP addresses are used to uniquely identify each device connected to a network. They’re like the street addresses of the IP network world. Nowadays, IP networks are largely prevalent but it hasn’t always been the case. Microsoft used to have NetBEUI networking, Novell NetWare had IPX/SPX, and Apple had AppleTalk. In fact, there was a time when each manufacturer used a different networking scheme. Back then, IP networks-which stands for Internet Protocol-were only used for-you guessed it-the Internet. Eventually, the Internet grew in popularity and it started to make sense for everyone to use IP networking. IP addresses soon became an essential part of every computer’s configuration. When we said that IP addresses were uniquely identifying each device, this was a bit of a stretch. In reality, IP addresses uniquely identify a device within a given context. Consequently, IP addresses need only to be unique within this context. The Internet is such a context but not all computers accessing the Internet need to be directly connected to it. Most users access the Internet through some sort of gateway and use local IP addressing, internally. In these situations, only the local addressing has to be unique and it’s not uncommon to have identical IP addresses used in different organizations. Take, for example, your typical home Internet WiFi router. Most of them have 192.168.0.1 as their internal IP address. That specific address is therefore present on most home networks. The very first step in planning a network in all but the smallest networks is preparing an IP addressing plan. The idea behind the plan is to define how IP addresses are going to be used. For instance, a range of IP addresses will likely be reserved for servers. Some will obviously be assigned to computers connected to the network. And of course, IP addresses will be reserved for other devices such as networking equipment or network-connected printers. This task is often done using simple tools such as spreadsheet software. The next task is assigning IP addresses to devices. This is what we refer to as IP address allocation. There are several ways this can be done as we shall soon see but for now, the important thing to keep in mind is that you need to keep track of what IP address is assigned to what piece of equipment. There are basically two ways IP addresses can be assigned: statically or dynamically.
