What changing your IP address actually does

Your IP address is the number your internet service provider assigns to your home network so websites and services know where to send data back to you. Changing it means getting a different number from your provider — which disconnects you from the old address and reconnects you to the new one. Most of the time this happens automatically without you doing anything. When you do it yourself, you are either asking your router to request a fresh address from your provider, or you are physically restarting the equipment that connects you to the internet.

People change their IP for a few real reasons: a website is blocking their old address, they want a different geographic location for streaming services, they are troubleshooting a connection problem, or they are trying to hide their address from someone on their network. The method depends on which of these you are trying to do, because some methods are temporary (lasting hours or days) and some are permanent (lasting until your provider assigns you a new one again).

Key Takeaways

  • Restarting your modem and router is the fastest way to request a new IP from your provider, and it usually takes 5 to 10 minutes to complete.
  • Unplugging your modem for 10 minutes forces your provider to assign you a fresh address, while restarting it normally may just restore the same one.
  • Changing your IP through your router settings lets you set a static address that stays the same, which is useful if you run a server or need consistent access from outside your home.
  • A VPN changes the IP address websites see, but it does not change your actual home IP — it just hides it behind the VPN provider's address instead.
  • Contacting your internet provider directly is the only way to may provide a permanent IP change if the automatic methods do not work.

Restarting your modem to request a new IP

The simplest method is to restart your modem — the box that connects your home to your internet provider's network. When you restart it, the modem disconnects from your provider and reconnects, which usually triggers a request for a fresh IP address. This takes about 5 to 10 minutes total and works on any internet connection type.

Unplug the power cable from the back of your modem (the box usually provided by your internet company, not your router). Wait 30 seconds, then plug it back in. The lights on the front will flash as it restarts. Wait until all the lights stop flashing and settle into their normal pattern — usually a solid light or two. Your internet should be back online with a new IP address.

If restarting the modem does not give you a new address, your provider may have assigned you a static IP, meaning it stays the same even after restart. In that case, you will need to contact your provider directly to request a change, or use one of the other methods below.

Unplugging your modem for a longer reset

If a normal restart does not change your IP, try a longer disconnect. Unplug your modem and leave it unplugged for 10 minutes. This gives your provider's system time to forget your old connection entirely, so when you plug it back in, it assigns you a completely fresh address instead of restoring the old one.

While the modem is unplugged, you can also unplug your router (the separate device that broadcasts your WiFi signal, if you have one). Plug the modem back in first and wait for it to fully restart — all lights stable — then plug in the router and wait another 2 to 3 minutes for it to come back online.

Setting a static IP through your router

A static IP is an address that does not change automatically. You set it once in your router and it stays the same until you change it again. This is useful if you run a home server, need to access your home network from outside, or want to avoid the automatic changes that happen every few months.

Open a web browser and type 192.168.1.1 or 192.168.0.1 into the address bar. This takes you to your router's settings page. Log in with your router's username and password — if you have never changed it, check the sticker on the back of the router or the manual that came with it. Look for a section called "LAN Settings", "Network Settings", or "DHCP". Find the option to set a static IP and choose an address in the range your router suggests — usually something like 192.168.1.100 to 192.168.1.254. Save the changes and restart your router.

This changes the IP address your devices use inside your home network, not the address your internet provider sees. If you want to change the address your provider assigns, you still need to restart your modem using the method above.

Using a VPN to hide your IP

A VPN (virtual private network) is software that routes your internet traffic through a server run by the VPN company. Websites see the VPN server's IP address instead of yours, which hides your real address. This is different from actually changing your IP — your home IP stays the same, but it is hidden behind the VPN's address.

read a VPN app from a reputable provider — common ones include ExpressVPN, NordVPN, or Mullvad. Install it, create an account, open the app, and click the button to connect. The app will show you a new IP address that websites now see. This address changes depending on which VPN server you connect to, and it changes back to your real IP when you disconnect the VPN.

A VPN is useful if you want to appear to be in a different country for streaming services, or if you want to hide your address from websites you visit. It does not change your actual home IP address, and it does not hide your address from your internet provider — they can still see all your traffic, they just cannot see where it is going.

Contacting your internet provider for a permanent change

If you have tried restarting your modem and unplugging it for 10 minutes without success, your provider may have locked your address as static. Call your internet provider's customer service number — it is on your bill or on their website. Tell them you want to request a new IP address. Some providers will change it for you over the phone. Others will tell you to restart your modem again, or they will schedule a technician visit.

Have your account number ready when you call. Explain that you have already restarted your modem and waited, so they know you have tried the basic step. Some providers charge a small fee for a manual IP change, though many do it for free if you ask. Ask before they make the change so you are not surprised by a charge.

Why your IP changes on its own

Your internet provider assigns IP addresses from a pool and recycles them when customers disconnect or when a set time period passes. This is called a DHCP lease — your provider "leases" you an address for a set number of days, usually 30 to 90 days. When the lease expires, your modem requests a new one, and you get a different address automatically. This is why people sometimes notice their IP has changed without doing anything.

You cannot stop this from happening unless you pay your provider for a static IP address, which is usually an add-on service that costs a few dollars per month. If you need your address to stay the same for work or technical reasons, ask your provider whether they offer static IP as an option and what it costs.

Frequently Asked Questions

Will changing my IP stop someone from tracking me online?

Changing your home IP stops someone on your home network from seeing your traffic, but it does not hide your address from websites you visit — they still see your new IP. If you want to hide your address from websites, use a VPN instead. Changing your IP does not protect you from tracking through cookies, accounts you are logged into, or other methods websites use.

Can I change my IP to a specific address I choose?

No. Your internet provider assigns addresses from their own pool, and you cannot request a specific one. You can set a static address inside your home network (for devices on your WiFi), but the address your provider assigns to your modem is their choice. A VPN lets you appear to be in a different country, but you still cannot pick the exact address.

How long does it take to get a new IP after restarting my modem?

Usually 5 to 10 minutes. Your modem disconnects, requests a new address from your provider, and reconnects. If you do not see a new address after 15 minutes, try unplugging the modem for 10 minutes instead, or contact your provider to check whether your address is set as static.

Does changing my IP affect my internet speed?

No. Your speed is determined by your internet plan and connection type, not by your IP address. Changing your IP does not make your internet faster or slower. If you use a VPN, your speed may decrease slightly because your traffic is being routed through an extra server, but that is a VPN effect, not an IP change effect.

What is the difference between my home IP and my device IP?

Your home IP is the address your internet provider assigns to your modem — websites see this address when you visit them. Your device IP is the address your router assigns to each device on your WiFi — other devices on your home network see this address, but websites do not. When you restart your modem, your home IP changes. When you restart your router, your device IPs change, but your home IP usually stays the same.
