Much like how a street address identifies where you live, an IP address functions as the identifying "street address" of the device, and allows companies to see where the device is located and route traffic to the nearest server for faster connections and lower latency. IP geolocation is the science of determining the physical location and Internet connection characteristics of a web visitor. IP geolocation is the technology upon which our Internet Location Intelligence platform is based.
Public vs. private IP addresses
IP geolocation maintains a person's privacy because what is being assessed is the point where the visitor connected to the Internet, locating a computer within a mile area — not a person, not an email, not a street address. Compare it to mailing a letter.

Take an envelope and write an address on it, seal it empty , do not include a return address, put a postage stamp on it, and mail it from a post office. The envelope will be stamped with a postal code indicating the location at which it entered the postal system. The envelope is in the postal system and will reach its destination, but there is no information about its contents or sender. Using warrants to obtain information from the Internet Service Provider ISP , law enforcement personal were able to track down the physical addresses of the hackers and arrest them for their illegal internet activity.

Login Newsletters. Stocks Tech Stocks. What Is an IP Address? Compare Investment Accounts. IPv4 vs. Knowing how to scan the network for devices is the first step, and one of the most fundamental, in managing IP addresses. When organizational members experience problems connecting their device to the network or the internet, having a full list of IP addresses on the network can guide administrators as they troubleshoot and restore order.
The most basic way to find all the IP addresses on a network is with a manual network scan. This method is best for those looking to perform a rapid, one-time device check or for those heading smaller organizations with a more manageable device list. To rapidly scan a network yourself using native operating system OS capabilities, follow these steps.

However, there are a few ways to scan local networks for IP addresses. Typically, the best way to find the IP addresses of all devices on a network is to invest in software. This is especially true for large organizations using dynamic IP addresses, in which case the large volume of networked devices and staggered address changes can quickly become overwhelming to track and organize. Using an IP address scanner, admins can see which addresses are active, which are free for reallocation, which might belong to unauthorized users, and which have perhaps been duplicated and caused collisions.
This is particularly true when you look at the data this method makes available to you. It merely enables you to identify IP addresses and spot possible duplicates or mismatches. For this reason, downloading software with a fuller suite of IP address management IPAM services is highly recommended. While some are free, these are generally more supplementary tools. Cobbled together, a collection of standalone software can certainly yield powerful results. In terms of expedient and comprehensive data consolidation, however, the best results tend to come from premium software.
By far the most powerful tool on the list of free clients, SolarWinds IP Address Tracker is a standalone solution, available for free download, that works on its own but is further enhanced by the SolarWinds IPAM suite when integrated. For a free tool, SolarWinds IP Address Tracker is extraordinary: not only does it allow users to manage up to IP addresses, but it automatically pushes alerts when IP address conflicts occur. Finally, its graphical user interface displays information in an intuitive and digestible format, highlighting notable events while remaining comprehensive in nature.
For example, it shows a list of custom reports, the last 25 IPAM events, current conflicts, and ranked subnets by the percentage of available addresses used. Widely hailed as one of the first and most popular free IP address scanners, Angry IP Scanner is open-source software, deployable across operating systems. Angry IP Scanner is easy to use and has an intuitive graphical user interface.
Further, it provides slightly more detail than the manual command-line method covered above. Given an IP address range, the tool displays all active IP addresses, hostname when applicable, ping response time, MAC address, and port count. The functionalities it offers are fundamental and useful.
Plus, anyone who writes Java is free to expand its abilities by creating their own plugins, though of course this would require a certain amount of buy-in. Created by developer 10base-t Interactive and optimized for Mac, this app is admittedly limited; the free version only supports 6 devices. In this mode, network admins can see inactive devices that were once part of the network.
This can help with troubleshooting in a variety of ways. Is this IP address now free for reallocation? Is this device supposed to be present, and something has gone wrong? IP Scanner takes some of the guesswork out of network fluctuations, making it possible to zero in on these questions and find answers.
By culling the display in this way, users can stay aware of which devices are new and may be on the network without authorization, receiving automatic alerts to potential threats. In addition to all the SolarWinds IP Address Tracker features covered above, IPAM is a complete management solution, empowering admins to drill down into address conflicts, easily allocate IP addresses to subnets, and catalogue IP address usage history. These functions are crucial time-savers. This allows admins to temporarily remove the malfunctioning devices by remotely shutting down a port, thus facilitating network reliability and high performance while reconfiguring IP settings behind the conflict.
As regards address allocation, IPAM users can employ the automated Subnet Discovery Wizard and Subnet Allocation Wizard to sort IP addresses and form optimally sized subnets, maximizing performance while minimizing conflicts and wasted space.
How Do IP Addresses Work?
Better yet, IPAM features drag-and-drop and user-defined grouping, making portioning IP address space more convenient than ever before. One last notable feature here is that it offers priceless server synchronization. This makes it possible not merely to set alerts for conflicts and put out fires as they arise, but to prevent potentially expensive address conflicts to begin with. This means customers can find available addresses, assign them, and update the DNS simultaneously, eliminating the possibility of misdirected traffic or duplication.
This includes a slate of tools fulfilling the duties of an IP tracker or scanner, bolstered by myriad others in this holistic network management client. SolarWinds ETS performs automated network discovery, allowing it to undertake clear network visualization—a capability not found in most free tools.
With the automated discovery, the toolset displays the network in its entirety, mapping out switch ports, relating MAC to IP addresses, and identifying equipment. Not only does the Ping Sweep tool provide a quick rundown of which addresses are in use and which are available for assignment, but it also locates the DNS name corresponding to each IP address. It supplements this data with graphs charting device response time. The Subnet Calculator at once scans subnets; generates the proper masks, size, range, and broadcast address of both classful and classless subnets; and acts as an IP address tracker, continuously monitoring the addresses in use within each subnet.
What Is IP Address Geolocation and How to Change It?
This is an incredibly important function when re-architecting a network or trying to avoid downtime, as it gauges whether the network is due to run out of addresses before a verifiable shortage arrives. This helps ensure if a device is using an IP address, the network reaps the rewards of having allocated that address. Coupled with the innumerable other amenities of SolarWinds ETS, its network scanning and IP address tracking features go even further in preventing network catastrophe, identifying problems early, ascertaining root causes, and executing quick resolutions. Its network device scanner tool automatically discovers network devices; beyond that, NPM creates visual displays that delineate the connections between devices — automatically populating maps that clarify network topology.
This is particularly helpful in the case of the dynamic IP address system, in which IP addresses in addition to device count and relationship are constantly in flux.
