How to Find All Devices on Your Network by IP Address (Windows)

📅 Aug 27, 2024⏱️ 8 min read✍️ SterJo Software📂 Network

Whether you're setting up a printer, troubleshooting a connection, or doing a security check — knowing every device on your network and its IP address is the first step. Here's how to get that complete list in under a minute.

This guide covers the most practical methods for finding all devices on a local network by IP address using Windows — from a dedicated free tool to built-in command-line options. We'll also explain when to use each method depending on whether you're on a home WiFi network or a larger office subnet.

Quick Answer: Pick Your Tool

Home WiFi (want MAC addresses + device type): Use SterJo Wireless Network Scanner — ARP-based, shows IP, MAC, hostname, and vendor.

Any network, custom IP range: Use SterJo Fast IP Scanner — scan 1,000+ IPs in under 30 seconds.

No download needed: Open Command Prompt → arp -a for a quick partial list.

Understanding Network IP Addresses

Every device on a local network is assigned an IP address by your router's DHCP server. On a typical home network, these follow the pattern 192.168.1.x or 192.168.0.x, where the last number (1–254) is unique per device. Your router also occupies an IP — usually .1 — and it manages the assignment of all others.

Finding "all devices by IP" means discovering which addresses in your network's range are actively in use. The tools and methods below accomplish this in different ways, with different tradeoffs.

How to Find Your Network's IP Range:

  1. Press Windows + R, type cmd, press Enter
  2. Type ipconfig and press Enter
  3. Note your IPv4 Address (e.g. 192.168.1.105) and Default Gateway (e.g. 192.168.1.1)
  4. Your scan range: same first three numbers as your IP, last number 1–254 (e.g. 192.168.1.1 to 192.168.1.254)

Method 1: SterJo Fast IP Scanner — Any Network, Any Range

SterJo Fast IP Scanner is the most flexible option. You define any start and end IP address and it pings every address in the range simultaneously using multi-threaded scanning — over 1,000 addresses in under 30 seconds. Each responding device shows its IP address and hostname.

Steps:

  1. Download SterJo Fast IP Scanner (free, 1.7 MB, portable available)
  2. Enter your network's start IP (e.g. 192.168.1.1) and end IP (e.g. 192.168.1.254)
  3. Click Scan
  4. Active devices appear immediately with IP address, hostname (reverse DNS), and response time

Method 2: SterJo Wireless Network Scanner — Best for Home WiFi

If you're on a home WiFi network and want more than just IP addresses — specifically MAC addresses, MAC vendor identification, and better detection of phones and IoT devices — SterJo Wireless Network Scanner is the better choice. It uses ARP rather than ping, which means it finds devices that actively block ICMP.

Steps:

  1. Download SterJo Wireless Network Scanner (free, 1.3 MB)
  2. Connect your PC to the WiFi network
  3. Run the tool — it auto-detects your wireless adapter
  4. Click Scan
  5. Every connected device appears with IP address, MAC address, hostname, and manufacturer

Method 3: ARP Command — Instant, No Downloads

Windows automatically maintains an ARP (Address Resolution Protocol) cache of devices your PC has recently communicated with. You can view this immediately without any tools:

arp -a

This shows IP address and MAC address for all recently-seen devices. Run it in Command Prompt (Windows + R → cmd → Enter). The output won't be a complete network map — it only covers devices your PC has directly talked to — but it's instant and reveals IPs and MAC addresses without any scanning.

To improve ARP cache coverage before running this command, do a ping sweep first:

for /L %i in (1,1,254) do @ping -n 1 -w 50 192.168.1.%i > nul && arp -a | find "192.168.1.%i"

Method 4: Router DHCP Table — Most Authoritative

Your router keeps a record of every IP address it has assigned via DHCP. This is the most authoritative list — it includes devices that may currently be offline but were connected recently.

How to Access:

  1. Open a browser and navigate to your router's admin IP (usually 192.168.1.1 or 192.168.0.1)
  2. Log in with your router credentials
  3. Look for DHCP Clients, Connected Devices, or LAN Clients in the menu
  4. The table shows each device's hostname, IP address, MAC address, and sometimes the lease expiry time

Frequently Asked Questions

1. How do I find the IP address of a specific device (like a printer)?

Run a scan with SterJo Fast IP Scanner or Wireless Network Scanner. Check the hostname column — printer hostnames often include the brand name (e.g. "HP-LaserJet", "EPSON", "BROTHER"). If the hostname doesn't help, check the MAC vendor column in the Wireless Network Scanner to identify the manufacturer.

2. Why do some devices appear with no hostname?

Many IoT devices, smart home hardware, and some phones don't broadcast a hostname. Their IP and MAC address still appear in the scan — use the MAC vendor to identify the device type.

3. Can I see which IP address is assigned to my phone?

Yes. Run a scan while your phone is connected to the same WiFi. Your phone will appear in the results. You can also check directly on your phone: on Android, go to Settings → Wi-Fi → tap your connected network → see IP address. On iPhone, go to Settings → Wi-Fi → tap the (i) next to your network → see IP address.

4. Are IP addresses on my home network permanent?

Usually not. Home routers use DHCP to assign IP addresses dynamically — the address a device gets today may be different next time it connects. Devices can be assigned a static (permanent) IP by configuring it in the router's DHCP reservation settings, which is useful for printers and servers.

5. What does it mean if I see 192.168.1.1 or 192.168.1.255 in my scan?

The .1 address is typically your router — the gateway device. The .255 address is the broadcast address used for network-wide messages, not a real device. Both are normal and expected in any scan results.

6. My scan shows far more devices than I expected. Is something wrong?

Not necessarily. Modern homes have many connected devices people forget about: smart plugs, light bulbs, thermostats, security cameras, smart speakers, gaming consoles, and more. Make a count of your WiFi-connected hardware — you'll likely find it matches the scan results. If there's a genuine unknown device after your inventory, see our guide on identifying unknown WiFi devices.

💡 Quick Tip

After scanning, use your router's DHCP reservation feature to assign a permanent (static) IP to your printer or NAS drive — it'll always be at the same address.

📊 Did You Know?

Running arp -a immediately after a ping sweep gives you both IP addresses and MAC addresses without any tools — it's the fastest built-in method for a partial device list.
