How to Find IP Address Using Command Prompt: Complete Windows Guide

So you need to find your IP address? Maybe your Netflix isn't loading, or you're trying to host a game server. Whatever the reason, pulling up Command Prompt is like that trusty screwdriver in your toolbox - not fancy, but gets the job done every time. I remember last month when my smart home devices went haywire. Spent 20 minutes clicking through Windows settings before remembering the good old cmd method. Three seconds later, I had what I needed.

IP Address Basics You Actually Need

Think of your IP address like your computer's mailing address on the internet. When you search for cat videos, that request needs a return address so YouTube knows where to send the data. Without it, you'd be shouting into the void.

There are two types you'll care about:

Type What It Does Who Sees It
Private IP (IPv4) Identifies your device on your home network Your router and local devices
Public IP Identifies your entire network to the outside world Every website and service you connect to

Why would you need these? Last week my neighbor couldn't print to his wireless printer. Turned out he needed the printer's private IP to fix the connection. Other times you might need your public IP when setting up security cameras remotely. Different problems, different addresses.

Why Command Prompt Beats Fancy Tools

Sure you could dig through ten layers of Windows menus or download some sketchy "IP Finder Pro" app. But why? Command Prompt for IP address lookup is:

  • Already installed on every Windows machine since XP
  • Lightning fast - we're talking under 5 seconds
  • Works even when your network settings are glitching out
  • Gives raw data without fluff

I once helped a friend troubleshoot his laptop in a coffee shop. The Wi-Fi was spotty, and the network settings panel wouldn't even load. Command Prompt? Worked first try.

Heads up: Some newer guides push PowerShell instead. It's fine, but honestly overkill for basic IP checks. Stick with cmd unless you're doing advanced scripting.

Your Step-by-Step Command Prompt IP Walkthrough

Let's get hands-on. Fire up cmd using any of these methods:

Method How To Works When...
Search Box Hit Windows key, type "cmd", press Enter Your start menu works normally
Run Dialog Windows + R, type "cmd", press Enter You need admin rights (add "runas /user:Administrator cmd" without quotes)
File Explorer Navigate to C:\Windows\System32, double-click cmd.exe All else fails

Now the magic happens. Type this and hit Enter:

ipconfig

You'll see something like this:

Windows IP Configuration Ethernet adapter Ethernet: Connection-specific DNS Suffix . : home IPv4 Address. . . . . . . . . . . : 192.168.1.25 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.1.1

See that "IPv4 Address" line? That's your private IP. Write it down or copy it (right-click > mark, highlight text, press Enter to copy).

When ipconfig Isn't Enough

Sometimes you need more details - like when setting up port forwarding. Add /all to the command:

ipconfig /all

Now you'll see MAC addresses, DNS servers, lease times... the whole networking buffet. Looks overwhelming? Here's what matters:

Term What It Means Why You Care
Physical Address Your device's MAC address Router whitelisting/blacklisting
DHCP Enabled Whether IP is auto-assigned Troubleshooting connection issues
Lease Obtained/Expires How long your IP is valid Diagnosing intermittent drops

Command Prompt Public IP? Not Exactly

This trips people up. Your public IP isn't stored on your computer - it's assigned by your ISP. But you can find it through cmd with a clever trick. Type:

nslookup myip.opendns.com resolver1.opendns.com

You'll get something like:

Server: resolver1.opendns.com Address: 208.67.222.222 Non-authoritative answer: Name: myip.opendns.com Address: 203.0.113.42

That "Address" under Non-authoritative answer? That's your public IP.

Annoyance alert: Some corporate networks block this. If it fails, you'll have to use a website like whatsmyip.com. Not as cool as pure cmd, I know.

Common Command Prompt IP Address Problems Solved

Let's tackle real issues I've seen:

No IP Address Showing Up

You run ipconfig and see:

Autoconfiguration IPv4 Address. . . : 169.254.75.201

That 169.254.x.x address means your computer gave up getting a real IP. Try this sequence:

ipconfig /release
ipconfig /renew

If that doesn't work, reboot your router. Still stuck? Might be a dead network card.

Multiple IPs Listed

Got both Ethernet and Wi-Fi? You'll see multiple sections. Look for:

  • "Ethernet adapter" for wired connections
  • "Wireless LAN adapter" for Wi-Fi

Disable the one you're not using in Network Connections to avoid confusion.

Forgotten Router IP

Need to access your router but forgot the address? In ipconfig output, find "Default Gateway" - that's your router's IP. Paste it into your browser.

Beyond Basics: Pro cmd Networking Tricks

Once you're comfortable with command prompt IP address lookups, try these:

Ping Testing

Test connection to a website:

ping google.com

See response times and packet loss. Essential for gaming or video calls.

Trace Routes

Where's the bottleneck? Find out with:

tracert google.com

Shows every hop between you and the destination.

ARP Table

See all devices on your local network:

arp -a

Lists IPs and MAC addresses - great for spotting unknown devices.

Security Stuff You Should Know

Finding your IP is safe. Sharing it? Not always.

Your private IP (192.168.x.x) is harmless to share. It's like sharing your apartment number without the building address.

Your public IP? Be careful. With it, someone could:

  • See your approximate location (usually city-level)
  • Attempt port scans (if you have open ports)
  • Launch targeted attacks (rare but possible)

That said, websites get your public IP anyway when you visit them. Just don't post it on forums with your home address.

Privacy tip: Use a VPN if you're paranoid. It masks your real public IP. But for most people, it's overkill unless you're torrenting or in a country with heavy censorship.

FAQs: Real Questions People Ask

Can I find IP addresses of other computers using cmd?

On your local network? Yes, use arp -a as mentioned earlier. For external addresses, no - that's physically impossible with just cmd.

Why does my command prompt ip address change?

Private IPs often change when devices reconnect. Public IPs usually stay the same unless your ISP rotates them or you restart your modem. Dynamic vs static IPs - that's a whole other article.

Is there a way to make my IP static?

For private IPs, assign reservations in your router settings. For public IPs? Contact your ISP and prepare to pay extra. Honestly not worth it for most home users.

Difference between ipconfig and ifconfig?

ipconfig is for Windows. ifconfig is for Linux and macOS. Same concept, different syntax. Mix them up and you'll get errors.

Command gave "not recognized" error?

Either you mistyped (check spelling) or your system files are corrupted. Run sfc /scannow in admin cmd to fix system files.

When Command Prompt Isn't the Answer

Look, cmd is great, but sometimes alternatives are better:

Scenario Better Tool Why
Checking internet speed Speedtest.net cmd can't measure bandwidth accurately
Detailed network analysis Wireshark Shows raw packet data
Managing multiple networks Windows Settings GUI makes profile switching easier

I love command prompt for IP address checks, but I'm not dogmatic about it. Use what works.

Putting It All Together

At the end of the day, knowing how to find your IP via Command Prompt is one of those fundamental tech skills like resetting a router. Seems trivial until you're in a pinch with no GUI access.

Remember these key points:

  • ipconfig for private IP (that 192.168.x.x number)
  • nslookup trick for public IP (or use a website)
  • Always run cmd as admin if commands fail
  • 169.254.x.x means network issues - release/renew first

Was this guide more helpful than those vague "just type ipconfig" articles? I hope so. Networking can feel intimidating, but it's just layers of simple concepts. Next time your Zoom drops out, you'll know exactly what to do before calling tech support.
