What changing your IP address actually does

Your IP address is a number assigned to your device by your internet provider — it's how websites and services know where to send data back to you. Changing it means your device gets a new number, which makes you appear to be in a different location online and breaks the connection history between your old address and your activity.

Most people change their IP address for one of three reasons: to reset a connection that has stopped working, to appear as a different user to a website or service that has blocked them, or to add a layer of privacy by not using the same address consistently. The method you use depends on which of these you're trying to do, and some methods are more reliable than others.

The simplest way — and the one that works for most connection problems — is to restart your modem and router. This tells your internet provider to assign you a new address. If you need a change that persists, or if you want to hide your address from websites, you'll need a different approach.

Key Takeaways

  • Restarting your modem and router forces your internet provider to assign you a new IP address within minutes, and this fixes most connection problems.
  • If restarting doesn't work or you need a permanent change, contact your internet provider — they can force a new assignment or, in some cases, give you a static address instead.
  • A VPN (virtual private network) hides your real IP address from websites and services, but it slows your connection slightly and costs money monthly.
  • Changing your IP address does not make you anonymous online — websites still see your activity, and your internet provider always knows which address belongs to you.

Restart your modem and router to get a new address fast

This is the fastest and most common way to change your IP address. Your modem is the device that connects to your internet provider's network; your router broadcasts that connection to your devices. When you restart both, your modem reconnects to the provider's network and requests a new address.

Unplug the modem first — the larger box that usually has cables running to it from the wall. Wait 30 seconds, then plug it back in. Wait another two minutes for it to fully restart; you'll see lights stop blinking and stabilize. Then unplug the router (the smaller box with antennas, usually), wait 30 seconds, and plug it back in. Wait another two minutes.

Once both devices have restarted, your modem will have requested a new IP address from your internet provider. You can check what your new address is by opening a web browser and searching "what is my IP" — you should see a different number than before. This change usually takes effect within five minutes but can take up to an hour in some cases.

This method works because most internet providers assign addresses temporarily — they expect devices to disconnect and reconnect regularly. The restart forces that disconnect and reconnect cycle. If you restart and your address doesn't change, your provider may have assigned you a static address (one that doesn't change), which is common for business accounts.

Contact your internet provider if restarting doesn't work

If you've restarted both devices and your IP address hasn't changed after an hour, call your internet provider's technical support line. Tell them you need a new IP address assigned. Most providers can force a new assignment over the phone in under five minutes.

Have your account number ready — it's usually on your bill or in the provider's app. The support agent will ask you to unplug your modem again while they process the change on their end, then plug it back in. When it reconnects, it will request a new address from the provider's system.

If your provider tells you that you have a static IP address and cannot change it, ask whether they offer dynamic addressing as an option. Some plans come with static addresses by default, but you can usually switch to dynamic (changing) addresses at no extra cost. This takes one to two business days to take effect.

Use a VPN to hide your IP address from websites

A VPN (virtual private network) doesn't change your actual IP address — your internet provider still sees it — but it hides it from websites and online services. When you use a VPN, websites see the VPN provider's address instead of yours, which makes it harder for them to track your location or link your activity across visits.

To use a VPN, you read an app from a VPN provider like ExpressVPN, NordVPN, Surfshark, or ProtonVPN. Open the app, click the button to connect, and it will route your internet traffic through the provider's servers. From that point on, websites see the VPN's address, not yours. The process takes about 30 seconds.

VPNs cost between $3 and $12 per month depending on the provider and plan length. They slow your internet connection slightly — usually between 5 and 20 percent — because your data has to travel through an extra server. They also don't make you anonymous; your internet provider still knows you're using a VPN and which websites you visit, and the VPN provider itself can see your traffic if they choose to log it.

A VPN is useful if you want to prevent websites from seeing your location, or if you're on public WiFi and want to prevent others on that network from seeing your activity. It's not useful if you're trying to hide your activity from your internet provider or if you need to appear to be in a specific location for a service that checks your address.

Why websites sometimes block IP addresses

Websites and services block IP addresses when they detect suspicious activity — multiple failed login attempts, automated scraping, or traffic patterns that look like a bot. When your address is blocked, you can't access the site from that address, even if your account is in good standing.

If you've been blocked, restarting your modem to get a new address will usually unblock you when ready, because the block was tied to the old address, not to your account. If you get blocked repeatedly, the service may be blocking your account itself rather than your address, which means a new address won't help.

Some services block entire ranges of addresses assigned to VPN providers or data centers. If you connect to a VPN and a website tells you that your access is blocked or restricted, try disconnecting from the VPN. The website is likely blocking that VPN provider's address range, not your personal address.

Static versus dynamic addresses and which one you have

A dynamic IP address changes periodically — usually every time you restart your modem, or automatically every few days or weeks depending on your provider's settings. Most home internet accounts use dynamic addresses. A static IP address stays the same indefinitely; your provider assigns it to your account and it doesn't change unless you request it.

To find out which one you have, restart your modem and check your IP address before and after using a search for "what is my IP". If the address is different after the restart, you have dynamic addressing. If it's the same, you likely have static addressing.

Static addresses are common for business accounts, security camera systems, or servers that need to be reachable at the same address all the time. If you have a static address and want to change it, you'll need to contact your provider and request a new one — they can't be changed by restarting. If you have dynamic addressing and want a permanent address that doesn't change, ask your provider about upgrading to static addressing; this usually costs $5 to $15 per month extra.

What changing your IP address does not do

Changing your IP address does not make you anonymous online. Your internet provider always knows which IP address is assigned to your account and which websites you visit. If someone has your account information or a court order, they can trace your activity back to you regardless of how many times you change your address.

It also does not hide your activity from your employer or school if you're using their network. Changing your personal device's IP address doesn't affect the network logs that the organization keeps. Those logs show which devices connected and what they accessed, independent of the IP address.

Changing your address also does not remove you from a website's records if you've already been identified. If you've posted under your real name or logged into an account, the website has a record of that activity tied to your account, not to your IP address. A new address won't erase that history.

Frequently Asked Questions

How long does it take to get a new IP address?

Restarting your modem usually results in a new address within 5 to 10 minutes. In rare cases it can take up to an hour. If you call your internet provider and ask them to force a new assignment, it usually happens within 5 minutes while you're on the phone.

Will changing my IP address disconnect me from the internet?

When you restart your modem and router, you will lose internet connection for 3 to 5 minutes while they restart. Once they come back online, your connection will be restored and you'll have a new IP address. You won't lose any data or settings.

Can I choose what my new IP address will be?

No. Your internet provider assigns addresses from a pool of available numbers. You cannot request a specific address unless you pay for a static IP address, in which case the provider assigns one address to your account and it stays the same.

Does a VPN change my IP address for my internet provider?

No. A VPN hides your address from websites, but your internet provider still sees your real address in their logs. The provider can see that you're using a VPN, but they cannot see which websites you visit through it.

What if I change my IP address and still can't access a website?

If the website is still blocking you after you've gotten a new address, the block is likely on your account rather than your IP address. Try logging out completely, clearing your browser's cookies, and logging back in. If that doesn't work, contact the website's support team and ask why your account is blocked.
