What changing your IP address does and why you might need to

Your IP address is the number your device uses to connect to the internet — think of it like a mailing address for data. Changing it can help if a website is blocking your connection, if you want a different location for streaming services, or if you're troubleshooting a network problem. The method depends on whether you want a temporary change (restart your router), a permanent change within your home network (set a static IP), or a change that masks your location (use a VPN).

Most people don't need to change their IP address. Your internet service provider assigns you one automatically, and it works fine for everyday use. But if you're having connection issues, need to reset your network, or want to appear to be in a different location, the steps below will get you there.

Key Takeaways

  • Restarting your router is the fastest way to get a new IP address from your internet service provider, and it usually takes 2 to 5 minutes.
  • Setting a static IP address on your device keeps the same address even after restarts, which is useful if you're running a home server or need consistent access to a device.
  • A VPN masks your real IP address and makes it appear you're in a different location, but it slows your connection slightly and requires a VPN service subscription.
  • On Windows, Mac, and mobile devices, the steps are different — Windows uses Settings or Command Prompt, Mac uses System Preferences, and phones use their Wi-Fi settings.
  • If you're changing your IP to fix a network problem, restart your router first before trying anything else.

The fastest way: restart your router to get a new IP from your provider

When you restart your router, your internet service provider assigns your modem a new IP address. This usually takes 2 to 5 minutes and works for most situations where you need a fresh connection.

Step 1: Unplug the power cable from the back of your router. Wait 30 seconds — this clears the device's memory.

Step 2: Plug the power cable back in. The lights on the front will blink as it restarts. Wait until they stop blinking and settle into a steady pattern (usually 2 to 3 minutes).

Step 3: Check your new IP address. On Windows, open Command Prompt and type ipconfig. On Mac, go to System Preferences > Network and look for "IPv4 Address". On your phone, go to Settings > Wi-Fi, tap your network name, and look for "IP Address".

Your old IP address is now released back to your provider's pool. If a website was blocking your old address, this usually fixes it.

Set a static IP address on Windows

A static IP keeps the same address on your device even after restarts. Use this if you're running a home server, need to access a device remotely, or want to set up port forwarding on your router.

Step 1: Open Settings and go to Network & Internet > Wi-Fi (or Ethernet if you're using a cable).

Step 2: Click on your network name, then scroll down and click "Edit" next to "IP settings".

Step 3: Change the dropdown from "Automatic (DHCP)" to "Manual". Turn on the IPv4 toggle.

Step 4: Enter an IP address in the range your router uses. Most home routers use 192.168.1.X (where X is a number between 2 and 254). For example, 192.168.1.100. Enter your subnet mask (usually 255.255.255.0) and gateway (usually 192.168.1.1 — this is your router's address).

Step 5: Click Save. Your device now keeps this IP address until you change it back.

If you're not sure what numbers to use, check your router's manual or log into it (usually by typing 192.168.1.1 into a browser) to see what range it assigns.

Set a static IP address on Mac

On Mac, static IP settings are in System Preferences rather than a Settings app. The process is similar to Windows but the menu names are different.

Step 1: Open System Preferences and click Network.

Step 2: Select your Wi-Fi or Ethernet connection from the left side, then click Advanced.

Step 3: Go to the TCP/IP tab. Change "Configure IPv4" from "Using DHCP" to "Manually".

Step 4: Enter an IP address (for example, 192.168.1.100), subnet mask (255.255.255.0), and router address (usually 192.168.1.1).

Step 5: Click OK, then Apply. Your Mac now uses this static address.

Change your IP address on iPhone or Android

On mobile devices, you can't truly change your IP address the way you can on a computer. But you can set a static address within your home network, or you can disconnect and reconnect to get a new address from your router.

For iPhone: Go to Settings > Wi-Fi, tap your network name, then tap the information icon (i). Scroll down to "IPv4 Address" to see your current address. To get a new one, go back and tap "Forget This Network", then reconnect — your router will assign a new address.

For Android: Go to Settings > Network & Internet > Wi-Fi, tap your network name, then tap Advanced. Look for "IP address" to see your current one. To get a new address, tap "Forget", then reconnect to the network.

If you want a static address on your phone, most routers let you set this from the router's admin panel rather than from the phone itself. Log into your router (usually 192.168.1.1 in a browser) and look for DHCP settings or "Reserved IP" to assign a permanent address to your phone's MAC address.

Use a VPN to mask your IP address

A VPN (Virtual Private Network) hides your real IP address and makes websites see a different one instead. This is different from changing your actual IP — you're routing your traffic through a VPN server so your real address stays hidden.

Step 1: Choose a VPN service. Common options include NordVPN, ExpressVPN, Surfshark, and ProtonVPN. Most charge a monthly fee (usually $3 to $12 per month), though some offer free versions with limitations.

Step 2: Download the VPN app for your device from the official website or your device's app store.

Step 3: Open the app, create an account, and log in.

Step 4: Tap the connect button. The app will route your traffic through a VPN server, and websites will see the VPN's IP address instead of yours.

Keep in mind that a VPN slows your internet connection slightly because your data travels through an extra server. It also won't help if a website is blocking you because of your account activity rather than your location — only a true IP change (restarting your router) fixes that.

Troubleshooting: what to do if your IP address won't change

If you've restarted your router and your IP address is the same, your internet service provider may have assigned you a static address. This is common with business accounts or certain service plans. Contact your provider and ask if they can release your IP and assign a new one.

If you're trying to set a static address on your device and it's not working, make sure you're using an address in the correct range for your router. Most home routers use 192.168.1.X, but some use 10.0.0.X or 172.16.X.X. Check your router's manual or log into it to confirm the range before entering a static address.

If a website is still blocking you after changing your IP, the block may be based on something other than your address — your account history, device fingerprint, or location data. In that case, a VPN might help, but restarting your router alone won't fix it.

Frequently Asked Questions

Will changing my IP address affect my internet speed?

Restarting your router or setting a static IP won't slow your connection. Using a VPN will slow it slightly because your data travels through an extra server, usually by 10 to 30 percent depending on the VPN service and how far away the server is.

Can I change my IP address to appear to be in a different country?

Yes, but only with a VPN. Restarting your router or setting a static address won't change your location — your internet service provider's location determines that. A VPN lets you choose a server in a different country, so websites see that location instead of your real one.

Do I need to change my IP address if my internet is slow?

Restarting your router (which gives you a new IP) is often the first troubleshooting step for slow internet, so it's worth trying. But slowness is usually caused by network congestion, distance from your router, or your service plan, not your IP address itself.

What's the difference between a static IP and a dynamic IP?

A dynamic IP changes each time you restart your device or router — your provider assigns a new one automatically. A static IP stays the same until you change it manually. Static is useful if you need consistent access to a device, but dynamic is fine for most everyday use.

Is it safe to use a free VPN?

Free VPNs work, but they often have limitations: slower speeds, fewer server locations, data caps, or ads. Some free services also sell your data to advertisers. If you use a VPN regularly, a paid service is usually safer and faster, though it costs a few dollars per month.
