The fastest way to find your public IP address is to open the IP Lookup tool. Your address appears in the result after the lookup runs. To find a private IP address, open the network settings on your phone or computer. Both checks normally take less than 30 seconds.

How to Find Your IP Address in 30 Seconds

Use this quick method to find your IP address:

  1. Open the lookup: Visit the public IP Lookup page on ipdnslookup.
  2. Run the check: The page checks the public address visible to internet services.
  3. Read the main result: Copy the IPv4 or IPv6 address shown at the top.
  4. Confirm the network: Check the ISP or organization to make sure it matches the connection you expect.
  5. Use location carefully: Country, region, city, and map values describe an approximate network area, not a precise device location.

This method finds your public address. If you need the address assigned to a device inside your Wi-Fi or office network, use the device instructions later in this guide.

Quick example

Suppose the lookup shows 203.0.113.25 as the main result. That is the public address visible to the website. Your laptop may separately show a private address such as 192.168.1.25 in its Wi-Fi settings. The two values have different jobs and can both be correct.

Public IP vs Private IP: Which One Do You Need?

A public IP address is used when your network communicates across the internet. Your internet provider, mobile carrier, workplace, VPN, or hosting provider supplies it. Websites can normally see this public address because they need it to return requested data.

A private IP address identifies a device inside a local network. A router may assign private addresses to your phone, laptop, television, printer, and other devices. Private IPv4 addresses commonly begin with 10, 172.16 through 172.31, or 192.168.

Choose the correct address for your task:

  • Use the public IP when checking what websites see, testing a VPN, reviewing public allowlists, or troubleshooting an internet-facing service.
  • Use the private IP when connecting to a printer, router, shared folder, development server, or another device on the same local network.
  • Use both when diagnosing whether a problem is inside your local network or between your provider and the internet.

How to Find Your Public IP Address

The easiest method works on Windows, macOS, Linux, Android, iPhone, and most other connected devices because it only needs a browser.

  1. Connect to the Wi-Fi, Ethernet, mobile network, or VPN you want to check.
  2. Open the My IP Address Lookup.
  3. Read the primary IP Address result.
  4. Review the provider, organization, address type, and approximate location.
  5. Copy only the address required for your task.

If you switch from Wi-Fi to mobile data, the public address will normally change because you are using a different network. Connecting to a VPN should usually show the VPN server's public address instead of the address assigned directly by your provider.

How to Find Your Private IP on Windows

Use Windows Settings

  1. Open Settings.
  2. Select Network & internet.
  3. Choose your active Wi-Fi or Ethernet connection.
  4. Open its properties.
  5. Find the IPv4 address or IPv6 address entry.

Use Command Prompt

Open Command Prompt, type ipconfig, and press Enter. Look under the active adapter. The IPv4 Address line shows the private address used by that Windows computer. Ignore disconnected adapters unless you are troubleshooting them.

The Default Gateway line usually shows the local address of your router. Do not confuse the gateway with the computer's own address.

How to Find Your Private IP on macOS

Use System Settings

  1. Open System Settings.
  2. Select Network.
  3. Choose the connected Wi-Fi or Ethernet service.
  4. Open Details if needed.
  5. Review the TCP/IP section for the local address.

Use Terminal

Open Terminal and run ifconfig to view network interfaces. The active interface contains an inet value for IPv4 and may contain an inet6 value for IPv6. The loopback value 127.0.0.1 points back to the Mac and is not its Wi-Fi address.

How to Find Your Private IP on Linux

Most Linux desktop environments show the address in the active connection's network settings. Open the Wi-Fi or wired connection details and look for IPv4 or IPv6.

From a terminal, run ip address or the shorter ip addr. Find the active interface and read its inet line. A result such as 192.168.1.40/24 includes the private address and its CIDR prefix.

You can enter that complete value in the CIDR Notation Calculator to find the normalized network, full address range, masks, capacity, and adjacent blocks.

How to Find Your Private IP on Android

Android menu names vary by phone maker and version, but the general path is similar:

  1. Open Settings.
  2. Select Network & internet, Connections, or a similar menu.
  3. Open Wi-Fi.
  4. Select the connected network or its settings icon.
  5. Open advanced details and find the IP address.

The value shown in Wi-Fi details is normally the private address assigned by the router. Turning off Wi-Fi and using mobile data creates a different connection and may not show the same local information.

How to Find Your Private IP on iPhone or iPad

  1. Open Settings.
  2. Select Wi-Fi.
  3. Tap the information button beside the connected network.
  4. Look in the IPv4 Address section.
  5. Read the IP Address value, not the Router value.

The same screen may show an IPv6 section. An iPhone can have both IPv4 and IPv6 addresses at the same time. Private Wi-Fi Address is a separate privacy feature for the device's Wi-Fi hardware identity and should not be confused with its Internet Protocol address.

How to Find an IP Address in Your Router

Your router can show the private addresses assigned to connected devices. Open the router administration page, sign in, and find a section named Connected Devices, DHCP Clients, Network Map, or something similar.

Use this method when you need the address of a printer, camera, television, or device without a convenient screen. Match the device name or hardware address carefully. Router interfaces differ, so follow the manufacturer's documentation.

Do not expose the router administration page to the public internet. Use a strong administrator password and install router security updates when available.

How to Check Whether a VPN Changed Your IP

  1. Disconnect the VPN and record the public IP shown by the lookup.
  2. Connect to the VPN server you want to test.
  3. Reload the lookup page and run the check again.
  4. Compare the public address, ISP, organization, country, and city.
  5. Confirm that the visible provider belongs to the VPN or hosting network you expected.

A changed address means the checked browser traffic is leaving through a different public endpoint. It does not prove that every application uses the VPN or that the connection has no privacy leaks. Use the result as one practical check, not a complete security audit.

Why Your IP Address May Be Different Tomorrow

Many providers assign a dynamic IP address. It can change after a router reconnects, a lease is renewed, maintenance occurs, or the provider reorganizes its network. Mobile connections change addresses frequently as devices move between carrier systems.

A static public address is intended to remain stable, but it can still change through an administrative action. Private addresses can also change when a router's DHCP service gives a device a new lease.

If a firewall, server, or remote service relies on an allowlisted address, verify whether your connection is static before depending on it.

Common Mistakes When Checking an IP Address

  • Copying the router address: The default gateway identifies the router inside the local network, not the device.
  • Using localhost: 127.0.0.1 and ::1 point back to the current device.
  • Confusing public and private values: A public website cannot normally use your 192.168 address to reach your device.
  • Choosing a disconnected adapter: Computers may list old VPNs, virtual machines, and unused network interfaces.
  • Treating IP location as GPS: City and coordinates are approximate network data.
  • Assuming one device has one address: A device can have private IPv4, public-facing IPv4, IPv6, loopback, and temporary addresses.

What to Do If No IP Address Appears

First, confirm that the device is actually connected. Open another website or check the Wi-Fi and Ethernet status. If the browser lookup does not load, restart the connection and try again.

For a missing private address, disconnect and reconnect to the network. A value beginning with 169.254 on Windows or macOS often means the device assigned itself a link-local address because it did not receive a normal IPv4 address from DHCP. Restarting the router or checking its DHCP settings may help.

If only IPv6 appears, the network may prefer IPv6 or may not provide public IPv4 directly. If multiple addresses appear, use the active interface and the version required by your task.

Privacy and Safe Sharing

An IP address is a normal part of internet communication, but it can still provide network context. Avoid publishing complete access logs or pairing addresses with personal information unless you have a legitimate reason and suitable privacy controls.

A normal lookup may estimate the provider, organization, country, region, or city. It does not directly provide a person's name, exact home address, passwords, files, or live GPS position. Providers may have private subscriber records, but those are not available through a public lookup.

When asking for technical support, share only the address that is necessary. A private address is usually enough for troubleshooting inside a trusted local network. Public addresses should be handled with the same care as other connection information.

Frequently Asked Questions

What is the fastest way to find my public IP?

Open the ipdnslookup IP Lookup tool and read the primary address result. It works from a browser on most connected devices.

Why does my phone show a different IP from my laptop?

They may use different private addresses on the same Wi-Fi, or one device may be using mobile data, a VPN, or another public connection.

Is the address in Wi-Fi settings public or private?

It is normally a private address assigned inside that Wi-Fi network. A browser lookup shows the public address visible to internet services.

Can I find my exact location from my IP?

No. Public IP location is an estimate for a network range and can point to a provider gateway or nearby city.

Why do I see both IPv4 and IPv6?

Many networks support both protocols. Applications can choose either version depending on network and destination support.

Does restarting my router change my public IP?

It may change a dynamic address, but the provider can assign the same value again. A restart does not guarantee a new address.

Can someone identify me from my IP alone?

An address alone normally identifies a network connection, not a person. Identity requires additional records and context.

Find the Right Address for Your Task

Use a browser lookup when you need the public address visible to websites. Use device network settings or a local command when you need the private address assigned inside your network. Always confirm whether the task requires IPv4, IPv6, public, or private information before copying a value.

Start with the IP Lookup tool, review the main result, and then use the device steps above when local details are needed. For address ranges, use the CIDR Notation Calculator or the IPv4 Subnet Calculator. Both provide immediate results without requiring an account.
