What changing your IP address actually does

Your IP address is how your device identifies itself on the internet — think of it like a return address on a letter. When you change it, websites and services see requests coming from a different location or device identity. This is useful if you want to reset your connection after network problems, hide your location from websites, or troubleshoot why a service is blocking you. It does not make you anonymous to your internet provider, and it does not bypass security systems designed to stop harmful activity.

The method you use depends on what you're trying to accomplish and what device you're on. Some changes happen automatically when you restart your equipment. Others require you to actively request a new address from your internet provider. A few involve using a tool that masks your IP address entirely — which is different from changing it, and comes with its own trade-offs.

Key Takeaways

  • Restarting your modem and router is the simplest way to get a new IP address from your internet provider, and it works on any device without extra software.
  • Your internet provider can see your IP address no matter what you do, so changing it does not hide your activity from them.
  • A VPN (virtual private network) masks your IP address from websites, but it routes all your traffic through a third-party company, which introduces different privacy trade-offs.
  • Static IP addresses — ones that stay the same — are set by your internet provider or your router, and changing them requires accessing your router's settings or calling your provider.
  • Changing your IP address does not remove you from blocklists or bypass security systems; it only works if the block was tied to that specific address.

Restart your modem and router to get a new IP from your provider

The fastest and most straightforward way to change your IP address is to power cycle your modem and router. Your internet provider assigns you an IP address when your modem connects to their network. When you restart the modem, it disconnects and reconnects, and your provider often assigns you a different address — though not always immediately.

Unplug your modem (the device that connects to your internet provider's line) and wait 30 seconds. Then unplug your router (the device that broadcasts WiFi to your home). Wait another 30 seconds, then plug the modem back in and wait for its lights to stabilize — usually two to three minutes. Then plug the router back in and wait for it to fully boot. Once both devices show a stable connection, your new IP address should be active.

This method works on every device in your home at once, because they all connect through the same modem. You do not need to change settings on your phone, laptop, or computer individually. The downside is that you have no control over what address you receive — your provider assigns it — and some providers assign the same address back to you after a restart.

Access your router settings to assign yourself a static or different local IP

Your router assigns IP addresses to devices inside your home (called local or private IP addresses). These are different from your public IP address, which is what the outside internet sees. If you want to change a device's local IP — for example, to make sure a printer always has the same address — you can set it in your router's settings.

Open a web browser and type 192.168.1.1 or 192.168.0.1 into the address bar. You will be asked to log in; the default username and password are usually printed on the router itself or in its manual. Once logged in, look for a section called DHCP, Local Network, or Connected Devices. From there you can either reserve a specific local IP for a device or manually assign one.

This does not change your public IP address — the one websites see — so it will not help if you are trying to get around a website block or hide your location. It is useful only if you need devices on your home network to have predictable addresses for technical reasons, like setting up a home server or ensuring a smart device always connects to the same address.

Use a VPN to mask your IP address from websites

A VPN (virtual private network) is software that routes your internet traffic through a server operated by the VPN company. Websites see the VPN server's IP address instead of yours, so your location and device identity appear masked. This is different from actually changing your IP address — your real address is still assigned to you by your provider — but it achieves a similar effect from the website's perspective.

To use a VPN, you download and install software on your device (or enable it in your phone's settings), create an account with a VPN provider, and turn it on before you browse. Popular options include Mullvad, ProtonVPN, and Windscribe, though many exist. Once active, your traffic appears to come from the VPN server's location, not your home.

The trade-off is that the VPN company can see all your traffic, so you are shifting trust from your internet provider to the VPN provider. Some VPNs keep logs of what you do; others claim not to. Read the privacy policy of any VPN you consider, because that company now has visibility into your browsing that your provider does not. A VPN is useful if you want to hide your location from websites or access content restricted to certain regions, but it does not make you anonymous to your VPN provider or to the websites you visit if you log into an account.

Contact your internet provider to request a permanent IP change

If restarting your modem does not give you a new address, or if you need a change that persists (does not reset when you restart), contact your internet provider's customer support. Explain that you want your IP address changed. Some providers will do this over the phone; others require you to submit a request online through your account portal.

Be prepared to explain why you want the change — for example, if you are having trouble with a service that is blocking your current address, or if you are experiencing network issues. The provider may ask you to restart your modem first to confirm a restart did not already assign you a new one. The change usually takes effect within a few hours to a day.

Some internet plans include a static IP address (one that does not change) as a paid add-on. If you have a static IP and want to change it, your provider can do that, but you may need to request it as a separate service change. Ask whether your plan includes a static IP and what it costs to change it.

Understand what changing your IP does and does not do

Changing your IP address will not hide your activity from your internet provider. They see all traffic flowing through your modem, regardless of what IP address is assigned to you. It also will not remove you from security blocklists or bypass firewalls designed to stop harmful activity — those systems often track behavior, not just IP addresses, so a new address alone usually does not help.

A new IP address is useful if a website or service has blocked your current address by mistake, if you want to reset your connection after network problems, or if you want to appear to be in a different location (though a VPN is more reliable for that). It is not useful for anonymity, bypassing security systems, or hiding from your internet provider.

If you are trying to solve a specific problem — like a website not loading, a service blocking you, or needing to appear in a different region — the right solution depends on the cause. A new IP address solves some problems but not others, so it is worth understanding what you are trying to accomplish before you restart your modem.

Frequently Asked Questions

Will changing my IP address make me anonymous online?

No. Your internet provider still sees all your traffic and knows it is you. Websites may not know your location or device, but they can still track you through cookies, login accounts, and other methods. A VPN hides your IP from websites but not from the VPN company itself. True anonymity requires multiple layers of tools and behavior changes, not just a new IP address.

How often does my IP address change on its own?

Most home internet providers assign IP addresses that change every few days to a few months, depending on the provider's settings. You do not have to do anything — it happens automatically when your modem reconnects. If you have a static IP address (usually a paid service), it stays the same until you request a change.

Can I change my IP address on just one device?

Not your public IP address — that is assigned by your internet provider to your modem, and all devices in your home share it. You can change a device's local IP address (the one it uses inside your home network) through your router settings. If you want a different public IP on one device, you would need to use a VPN on that device only.

What should I do if a website says my IP is blocked?

First, restart your modem and wait a few hours to see if your provider assigns you a new address. If that does not work, contact the website's support team and ask why you are blocked and whether the block is temporary. Some blocks are automatic and lift after a period of time. If the block is permanent, a VPN can help you access the site, but the website may block VPN addresses too.

Is using a VPN safe?

A VPN is as safe as the company running it. Read the privacy policy to understand what data they collect and whether they keep logs. Reputable VPN providers encrypt your traffic so your internet provider cannot see what you are doing, but the VPN company can. Choose a provider with a clear privacy policy and a track record of not cooperating with data requests if privacy is your main concern.
