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

Your IP address is a number that identifies your device on the internet — like a mailing address for data. When you change it, you're assigning a new number to your computer, phone, or router. Most home networks do this automatically through a process called DHCP, which hands out temporary addresses that refresh periodically. You can also force a change manually, or request a permanent static address from your internet service provider.

Homeowners change their IP for a few practical reasons: troubleshooting a connection problem, hiding your location from websites, testing network equipment, or preventing a device from being tracked across sessions. The method depends on which device you want to change and whether you want the change to stick or just happen once.

Key Takeaways

  • Restarting your modem and router is the simplest way to get a new IP address, and it works because your ISP reassigns addresses when devices reconnect.
  • You can manually change your IP address through your device's network settings, but the change usually reverts when you reconnect or restart.
  • A static IP address from your ISP stays the same until you change it, but costs extra and is rarely necessary for home use.
  • Using a VPN masks your real IP address from websites you visit, though it does not change your address on your home network itself.

Restarting your modem and router to get a new IP

The fastest way to change your IP address is to power cycle your modem and router. When you turn them off and back on, your modem reconnects to your internet service provider, which assigns it a new IP address. This new address then flows to all your devices.

Unplug your modem first and wait 30 seconds. Then unplug your router and wait another 30 seconds. Plug the modem back in and wait for its lights to stabilize — usually two to three minutes. Then plug in the router and wait for it to fully boot. Check your IP address through a search like "what is my IP" to confirm it changed. This method works on any device connected to your network and requires no technical knowledge.

The new address is temporary. Your ISP will assign a different one the next time your modem reconnects, which could be days or weeks away depending on your lease time. If you need a permanent change, you'll need a static address instead.

Manually changing your IP address through device settings

You can also change your IP directly on individual devices by accessing network settings. The steps differ by operating system, but the concept is the same: you tell your device to use a specific address instead of accepting one automatically from your router.

On Windows: Open Settings, go to Network & Internet, then Status. Click "Change adapter options," right-click your network connection, select Properties, then Internet Protocol Version 4 (IPv4). Choose "Use the following IP address" and enter a new address in the range your router uses — typically 192.168.1.X or 192.168.0.X, where X is a number between 2 and 254. Enter your router's address as the gateway (usually 192.168.1.1 or 192.168.0.1). Click OK.

On Mac: Open System Preferences, go to Network, select your connection, and click Advanced. Under TCP/IP, change "Configure IPv4" from Automatic to Manual. Enter your new IP address, subnet mask (usually 255.255.255.0), and router address. Click OK and Apply.

This change persists until you restart your device or manually switch back to automatic. It only affects that one device, not your whole network.

Getting a static IP address from your ISP

A static IP address is one that stays the same indefinitely. Your ISP assigns it and it remains yours until you request a change. This is useful if you run a home server, need consistent remote access, or want a permanent address for security cameras.

Contact your internet service provider and ask about static IP service. Most charge an extra fee — typically $10 to $20 per month — and require you to have a business account or meet other conditions. Your ISP will provide you with the static address, gateway, and DNS settings. You then enter these into your modem's configuration page or your device's network settings, depending on whether you want the address on the modem itself or on a specific device.

Static addresses are overkill for most home use. They cost money, and your ISP can still see all your traffic. They're mainly useful for people running services that need a predictable address.

Using a VPN to mask your IP address

A VPN (virtual private network) does not change your IP address on your home network, but it masks your real IP from websites you visit. When you connect to a VPN, your traffic routes through an external server, and websites see the VPN server's IP instead of yours.

This is different from changing your IP address locally. Your router and devices still use the same addresses they did before. But to the outside internet, you appear to be in a different location. VPN services are paid subscriptions — usually $5 to $15 per month — and they slow your connection slightly because traffic has to travel through an extra server.

A VPN is useful if you want privacy from websites or your ISP, but it does not solve network problems or help with local device communication. If you need to change your IP for troubleshooting, restart your modem instead.

When changing your IP address won't solve your problem

Many people assume a new IP address will fix connection issues, but most network problems have other causes. If your internet is slow, dropping, or unreachable, changing your IP usually won't help. The problem is typically with your modem, router, ISP connection, or the device itself — not the address it's using.

Restart your modem and router first. If that doesn't work, restart the device that's having trouble. Check that cables are plugged in firmly and that your router is in an open location away from metal and thick walls. If the problem persists, contact your ISP — they can check the line from outside your house and see if the modem is connecting properly.

Changing your IP makes sense only if you're testing network equipment, need a permanent address for a service, or want privacy from websites. For almost everything else, the issue lies elsewhere.

Frequently Asked Questions

Will changing my IP address make my internet faster?

No. Your IP address is just a label for your device. Speed depends on your ISP's service, your modem and router quality, and how far you are from the router. If your connection is slow, restart your modem and router, move closer to the router, or contact your ISP to check the line.

Can I change my IP address to a different country?

Not by changing your local IP. You can use a VPN to appear to be in a different country to websites, but your home network address stays the same. A VPN routes your traffic through a server in another location, masking your real IP from the sites you visit.

Does changing my IP address hide me from my ISP?

No. Your ISP assigns your IP address and can see all traffic on your connection regardless of what address your device uses locally. A VPN can hide your activity from your ISP, but changing your IP address cannot.

How often does my IP address change automatically?

It depends on your ISP's lease time, which is usually between one day and several months. Most home users see a new IP address every few weeks to a few months, though you may keep the same one for longer. You can check your current lease time in your modem's settings page.

What if I manually set an IP address and it conflicts with another device?

Your network will become unstable — devices may lose connection or communicate slowly. Switch back to automatic IP assignment in your device's network settings. If the problem persists, restart your router to reset all addresses.
