Mar 18, 2019 An Internet Protocol (IP) address is a unique sequence of values separated by periods. Modern IP addresses adhere to version 4 (IPv4) or version 6 (IPv6). Example of an IPv4 address: 12.301.405.2 Example of an IPv6 address: 2001:0db8:5078:31c3:0000:0000:31fd:fe04 Each device connected to your router can be identified by its unique IP address. Feb 25, 2020 After connecting the computer to the router, you can click the Search button to find the IP address of your wireless router/AP. If you want to manage your router, please choose the model name or WiFi SSID of the wireless AP that you want to manage and click Setting to login to the router. How to uninstall the Device Discovery. Private IP addresses operate only within the local network, so you and your neighbor, in theory, could be using the same private IP addresses. Since your IPs are on different networks, they don’t have to be unique. Two devices on the same LAN (local area network), however, can’t have the same private IP addresses.

What is my IP Address?

Sep 02, 2019 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. How to find IP on a network: Here are some simple command-line queries to find your entire network device’s IP addresses and information on how to track all IP assignments. In order to get a list of the IP of all of the devices connected to your entire network, follow these steps: Open a terminal window to get to the command line.

The IP Address of this machine is:

188.40.85.20

This address can also be represented as 3156759828 (32 bit decimal number) or 0xBC285514 (32 bit hexadecimal number).

(NB - if you are part of an internal network then this is the IP address of your local server, the machine which is connected to the external internet.)

What is an IP Address?

How to find ip addresses of devices on my network connection

'IP' (Internet Protocol) is the method used for sending and receiving information over the Internet. Any device that is required to communicate over the Internet is assigned a 32-bit number, its IP address, which uniquely identifies it to other devices. The IP address is usually written as a set of four numbers in the range 0-255 separated by dots, although it can also be shown as one big number in decimal or hexadecimal.

How are IP addresses used?

Whenever data is to be transmitted to a particular machine, it is broken up into chunks, or packets, each of which is tagged with the IP address of the destination machine. Each packet is transmitted separately, and will not necessarily follow the same route through the network as the other packets that make up the whole message. It is quite possible that the packets will arrive out of sequence, or with errors. Some may not even arrive at all.

On receipt the packets are automatically reassembled into the correct sequence so as to reconstruct the original data; if there are any errors or missing packets then they are requested to be sent again.

Private IP Addresses

Three ranges of IP numbers are reserved for local or private IP addresses - these are addresses which identify a device on a local network which is isolated from the internet by a router with Network Address Translation.

The three ranges are:
10.xxx.xxx.xxx
172.(16-31).xxx.xxx
192.168.xxx.xxx

These addresses are never used on the public internet. Typically, behind a NAT device, a sub-range from one of these ranges will be used to identify devices on a local network.

How are IP Addresses Assigned?

IP Addresses are hierarchical in nature - that is to say, one part of the IP address will specify broadly in which region of the network the destination can be found, with subsequent parts of the address providing more specific information about the location of the target device within that region. Consequently the allocation of IP addresses needs to be carefully managed, in order to maintain this hierarchy.

The allocation is overseen by the Internet Assigned Numbers Authority (IANA) and Regional Internet Registries (RIRs), who maintain a publicly accessible database called WHOIS, relating IP Numbers to locations in the network.

What is IPv6?

An IP address as described above is made up of four bytes, in a format known as IPv4. Four bytes can be used to represent over four billion different individual addresses, which might seem sufficient to uniquely label every computer in the world - but with more and more devices being connected to the internet the number of IPv4 addresses which are free to be allocated is dwindling.

IPv6 mitigates this problem by using sixteen bytes instead of four, which allows approximately 3.4x1038 unique addresses to be represented. In addition, the standard solves various other technical problems that IPv4 suffers from.

Unfortunately IPv6 is not interoperable with IPv4, so in order to use it all the internet hardware between IPv6 nodes will need to be updated to be able to use IPv6. Until that happens an IPv6 network is effectively invisible to IPv4 systems, and vice versa, although it is technically possible to implement converter nodes that embed one protocol within the other to allow connections between the different networks.

Who owns an IP Address?

Whilst you may not be able to track an owner of an IP address, you can usually find out its location. If you know the IP address, enter it on this free tool: ip lookup - also known as IP Geolocation - GeoIP.

Do you know what’s on your network? In this guide, we’ll show you a few simple ways you can find an IP address on your network. We’ll also go over a few great tools that can speed up this process and give you further insight into your network.

Whether you’re managing an office network, or just doing some troubleshooting at home, knowing how to find a device’s IP address is critical in solving a number of networking problems.

How To Find Ip Addresses Of Devices On My Network

Let’s start with the most basic method of finding your own local IP address in two easy steps.

  1. Open a command line window. In Windows, you can do this by pressing Windows Key + R, and then typing cmd in the Run box and hitting enter. In Linux, this can be done by pressing Ctrl+Alt+T.
  2. Type ipconfig in the command line if you’re on Windows, and ifconfig if you’re on Linux. Press enter to get a list of your PC’s IP configuration.

In the command prompt, you’ll find your IPv4 address towards the top. Under it, you’ll see your subnet mask and your default gateway. This information is vital, especially if you’re having issues connecting to the internet.

But what about finding other IP addresses that might be on your network?

To find other IP addresses that are on your local network, type arp -a in the same command prompt window and press enter. A list of IP addresses will populate on your screen along with additional information you might find helpful.

IP Addresses

In the far left-hand column you’ll see a list of IP addresses that were discovered on your network. Towards the bottom of the list, you may see some addresses starting with 224, 239, or 255. These addresses are generally reserved by your router for administrative purposes, so these can be looked over.

Physical Addresses

In the second column under Physical Addresses we’ll see each device’s physical address. This is also commonly referred to as a MAC address. A physical address is a unique identifier that every network device comes with. Unlike IP addresses, this number cannot be changed. Knowing a device’s physical address is important, especially if you want to identify exactly what is on your network.

Type

Find Device Name From Ip

The last column displays the address’s type. There are two types of IP addresses, dynamic and static. A dynamic address means that a DHCP server gave that device an IP address. A static address means that the device was configured to use a specific IP address, one that won’t change.

Static addresses are great for devices that are permanent, like printers or servers. Most home networks will be fine using DHCP to hand out IP addresses. DHCP servers assign IP addresses that have leases. Once that lease is up, that device might get a different IP address.

Troubleshooting

From your command prompt, you’re a bit limited in how you can interact with devices on the network. You can attempt to ping an IP address on your network by typing ping 192.168.XX.XXX (Replace the X’s with your IP address.)

Most devices will answer the ping and reply back. This is a quick and easy way to determine if there are any latency issues between your PC and that device. For further troubleshooting, we’re going to need to use some network analyzer tools.

These tools are great for quickly finding devices on your local network and spotting problems fast. They also provide a lot more details than your trusty old command prompt can give you.

Below are three of my favorite network scanning programs.

SolarWinds Port Scanner (FREE TOOL)

If you need more detail and functionality from your Port Scanner then SolarWinds has you covered. You can easily scan your network by IP ranges and filter by ports to identify what services a device is running. SolarWinds Port Scanner is currently a Windows tool only.

SolarWinds Port Scanner also automatically resolves hostnames to help you identify what devices are on your network faster. The GUI interface is easy to use and boasts a cleaner display than Angry IP Scanner.

For those who live in the command line, you’ll be glad to hear this tool comes with a fully functional CLI and support for batch scripting.

While these tools are great, they won’t proactively alert you to problems on your network such as duplicate IP addresses, or DHCP exhaustion.

If you’re a small business administrator, or just a curious tech looking for a bit more insight into your network, SolarWinds Port Scanner is an excellent tool and is available as a free download.

Paessler PRTG Network Scanning Tools (FREE TRIAL)

If you’re a network administrator like myself, you’ll find PRTG Network Monitor an extremely valuable tool when it comes to troubleshooting problems across your network. PRTG is really the evolution of a scanning tool and more of a complete network monitor.

PRTG first scans the entire network in its network discovery process, listing any devices it can find. Once the scan is complete it keeps a real-time inventory of all devices and records when any are removed or added.

PRTG’s sensors are perfect for in-depth testing across your networks. Ping sensors can easily monitor a device’s connectivity over the long term, and alert you to those intermittent connection problems that can be difficult to pin down.

The PRTG scanner goes a step further by also incorporating database monitoring into its suite of tools. This sensor will alert you to any outages or long wait times in almost any SQL environment. Database monitoring can help identify small problems such as stalled processes before they cause major downtime.

Lastly, PRTG can thoroughly monitor bandwidth and network utilization for your environment. When things slow to a crawl, you’ll be able to quickly identify which IP addresses are using the most bandwidth and pinpoint exactly what that traffic is.

Is someone streaming too much Netflix? With the usage monitoring sensor, you’ll never have to guess what is hogging up your bandwidth again. This data is beautifully displayed as a chart, and broken down by IP address, protocol, or top connections.

When you have a sample of data you’d like to save, you can easily export it to XML or CSV. You can even tap into the PRTG API and export your data in real-time.

PRTG is a powerful on-premise tool and is geared mostly for medium to large businesses. It installs in a Windows server environment and gives you full control of what sensors you’d like to activate. If you’d like to test it out yourself you can download a 30-day free trial.

Angry IP Scanner

One of my favorite free tools is the Angry IP Scanner. It’s compatible with Mac, Linux, and Windows and allows you to quickly find detailed information about devices that are on your network.

Simply select an IP range at the top and let Angry IP Scanner work its magic. Almost instantly Angry IP will begin pulling information about the IP range you specified.

At a glance you’ll be able to see what IP addresses are open for assignment, taken by devices, and how many ports each device has open.

If you’re having trouble finding a device on your network, Angry IP Scanner makes it simple to track down that device for further troubleshooting.

Angry IP Scanner has personally helped me find devices that have lost their static IP address without having to physically go to the device.
