What changing your IP address means and when you might do it

Your IP address is a number assigned to your device that lets websites and networks identify where you are. Changing it means getting a new number assigned — either by restarting your router, switching networks, or using a tool like a VPN. Most people change their IP address to fix a connection problem, hide their location from websites, or get around a block that was placed on their old number.

The method depends on what kind of IP address you want to change. Your public IP address (the one websites see) is assigned by your internet provider and changes when you restart your router or move to a different network. Your local IP address (the one your home network uses) can be changed in your device settings. A VPN (virtual private network) masks your public IP by routing your traffic through another server.

Key Takeaways

  • Restarting your router is the simplest way to get a new public IP address from your internet provider, and usually takes 5 to 10 minutes.
  • Your local IP address can be changed in your device's network settings, but most people do not need to do this unless a technician tells them to.
  • A VPN changes how websites see your location by routing your traffic through a server in another place, though it does not change your actual IP address.
  • Changing your IP address does not erase your browsing history or make you anonymous — websites can still track you through cookies and other methods.

Restarting your router to get a new public IP address

The easiest way to change your public IP address is to power off your router, wait a few minutes, and turn it back on. Your internet provider will assign your router a new IP address when it reconnects to the network. This works because most home internet uses DHCP (Dynamic Host Configuration Protocol), which assigns temporary addresses that change periodically.

To do this: unplug your router from power, wait 30 seconds to 2 minutes, then plug it back in. Wait another 2 to 5 minutes for it to fully restart and reconnect. You can check if your IP address changed by visiting a site like whatismyipaddress.com before and after the restart. If the number is different, the change worked.

This method works on any device connected to that router — your phone, laptop, or tablet will all get new local IP addresses too. However, if your internet provider assigned you a static IP address (which some business accounts have), restarting the router will not change it. Static IPs stay the same until you contact your provider and ask them to change it.

Changing your local IP address in device settings

Your local IP address is the number your device uses on your home network — it is different from the public IP that websites see. You might need to change this if a technician told you to, or if you are setting up a network and need to avoid conflicts. The steps differ depending on whether you use Windows, Mac, iPhone, or Android.

On Windows: Open Settings, go to Network & Internet, then Status. Click "Change adapter options," right-click your network connection, select Properties, then click "Internet Protocol Version 4 (TCP/IPv4)." Choose "Use the following IP address" and enter a new address in the same range as your router (usually 192.168.1.X, where X is a number between 2 and 254). Click OK.

On Mac: Open System Preferences, go to Network, select your connection, and click Advanced. Go to the TCP/IP tab and change the "Configure IPv4" dropdown to "Manually." Enter a new IP address in your router's range, then click OK.

On iPhone or iPad: Go to Settings, tap Wi-Fi, find your network, tap the info icon, and select "Configure IP." Choose "Manual" and enter a new address. On Android, the process varies by manufacturer, but usually involves Settings > Network > Advanced > IP Settings, then choosing "Static" and entering a new address.

Using a VPN to mask your IP address

A VPN does not change your actual IP address, but it hides it from websites by routing your traffic through a server in another location. When you use a VPN, websites see the VPN server's IP address instead of yours. This is useful if you want to hide your location, access content blocked in your region, or use public Wi-Fi more safely.

To use a VPN: download a VPN app (common ones include ExpressVPN, NordVPN, Surfshark, and ProtonVPN), create an account, install the app, and turn it on. The app will connect to a server and assign you a new IP address to use. Most VPNs let you choose which country's server you want to connect through. Once connected, your device will use that server's IP address for all traffic.

VPNs are not free in most cases — they charge a monthly or yearly subscription. Some offer free trials or limited free versions. Keep in mind that a VPN does not make you completely anonymous; your VPN provider can still see your traffic, and websites can still track you through cookies and other methods. Choose a VPN provider with a clear privacy policy if you are concerned about who sees your data.

When your IP address might be blocked and how to respond

Websites and services sometimes block IP addresses if they detect suspicious activity, spam, or repeated failed login attempts. If you cannot access a site or service, the block might be on your IP address rather than your account. Changing your IP address (by restarting your router) is often the fastest way to regain access.

Before you restart your router, try these steps: clear your browser's cookies and cache, try accessing the site from a different device on the same network, or wait a few hours and try again. If none of that works, restart your router to get a new IP address. If the block persists after that, contact the website's support team and explain what happened — they can sometimes manually remove the block or help you figure out why it was placed.

If you are blocked repeatedly, the issue might be with your internet provider's IP address range rather than your individual address. Some providers' addresses are flagged as spam sources. In that case, contact your internet provider and ask if they can assign you a different IP address or explain why yours is blocked.

What does not change when you change your IP address

Changing your IP address does not erase your browsing history, cookies, or account logins. Websites can still identify you through your browser cookies, login sessions, and device fingerprinting even if your IP address changes. If you want to clear your browsing history, you need to do that separately in your browser settings.

Changing your IP also does not make you anonymous online. Your internet provider still knows which IP addresses they assigned to you and when. If law enforcement or a website owner needs to identify you, they can contact your provider and get that information. A VPN adds a layer of privacy by hiding your IP from websites, but it does not prevent your provider from seeing your traffic or your device from being identified through other means.

Frequently Asked Questions

Will changing my IP address fix my internet connection?

Sometimes. If your connection is slow or dropping, restarting your router (which changes your IP) can help by forcing it to reconnect and clear temporary problems. If the issue persists after a restart, the problem is likely something else — contact your internet provider for help.

Can I change my IP address without restarting my router?

You can change your local IP address in your device settings without restarting. To change your public IP address without restarting, you can use a VPN or connect to a different network (like mobile data or a different Wi-Fi network). Restarting is the most reliable method, though.

How often does my IP address change on its own?

Most home internet providers assign IP addresses that last 24 to 30 days before automatically renewing. Your IP might also change if your router loses power or your provider has an outage. You will not notice this happening — it occurs in the background.

If I use a VPN, can websites still see my real IP address?

No. When a VPN is active, websites see only the VPN server's IP address. However, your internet provider can still see your traffic, and your device can still be identified through cookies, browser fingerprinting, and login information.

Do I need to change my IP address to stay safe online?

Changing your IP address alone does not make you safer. Use strong passwords, enable two-factor authentication, keep your software updated, and be cautious about what you download. A VPN adds privacy on public Wi-Fi, but it is not a substitute for these basic security practices.
