What changing your internet address means

Your internet address, or IP address, is the number that identifies your device on your network and to the wider internet. It looks like four numbers separated by dots: 192.168.1.5 or something similar. Changing it means assigning a different number to your device — usually to fix a conflict where two devices have the same address, to organize your network better, or to reset a device that is misbehaving.

Most home networks assign addresses automatically through a system called DHCP. Your router hands out these addresses when devices connect, and they can change over time. You can also set a fixed address manually, which stays the same until you change it. The method you use depends on whether you want the change to be temporary or permanent, and whether you are changing one device or setting up a pattern for all devices.

Key Takeaways

  • Your router assigns internet addresses automatically, but you can change them through your router's settings or on individual devices.
  • A temporary change happens when you restart your device or router; a permanent change requires you to set a fixed address in your router or device settings.
  • The fastest way to get a new address is to restart your device, which usually triggers your router to assign a different one.
  • Fixed addresses are useful for devices that need to stay at the same address, like printers or security cameras, but they must not conflict with the range your router uses for automatic assignment.

Restart your device or router for a quick address change

The simplest way to change your internet address is to restart the device. When it reconnects to your router, the router will usually assign it a different address from the pool it has available. This works because your router forgets the old assignment when the device disconnects.

To restart: turn off the device completely, wait 30 seconds, and turn it back on. If restarting one device does not give you a new address, restart your router instead. Unplug it from power, wait 30 seconds, and plug it back in. When it finishes restarting (usually two to three minutes), all connected devices will reconnect and may receive new addresses.

This method is temporary — the next time you restart, you might get the same address back or a different one, depending on what other devices are connected. Use this approach when you just need to clear a conflict or reset something quickly.

Set a fixed address on your device

If you want a device to keep the same address every time it connects, you can set a fixed address directly on that device. The steps vary by device type.

On Windows: Open Settings, go to Network & Internet, then Status. Click "Change adapter options," right-click your network connection, and select Properties. Find "Internet Protocol Version 4 (TCP/IPv4)" and click Properties. Select "Use the following IP address" and enter your desired address (for example, 192.168.1.50), your subnet mask (usually 255.255.255.0), and your gateway (usually 192.168.1.1 — the address of your router). Click OK.

On Mac: Open System Preferences, go to Network, select your connection, and click Advanced. Go to the TCP/IP tab, change "Configure IPv4" from "Using DHCP" to "Manually," and enter your desired address, subnet mask, and router address. Click OK and explore.

On iPhone or iPad: Open Settings, tap Wi-Fi, find your network, tap the info icon next to it, and scroll to "Configure IP." Change from "Automatic" to "Manual" and enter your address details.

On Android: Open Settings, go to Wi-Fi, long-press your network name, tap "Modify," expand "Advanced Options," and change "IP settings" from "DHCP" to "Static." Enter your address details.

When you set a fixed address, make sure it does not fall within the range your router uses for automatic assignment. Most routers assign addresses from 192.168.1.100 to 192.168.1.254, so use something like 192.168.1.50 or lower for fixed devices. Check your router's manual or settings to confirm its range.

Reserve an address in your router settings

A cleaner way to assign fixed addresses is through your router itself, using a feature called DHCP reservation or static DHCP. This tells your router to always give a specific device the same address, without you having to configure the device manually.

To set this up, log into your router's admin page. Open a web browser and type your router's address (usually 192.168.1.1 or 192.168.0.1) into the address bar. Log in with your router's username and password — if you have not changed these, check the sticker on the back of your router or its manual.

Once logged in, look for a section called DHCP, Reserved Addresses, Address Reservation, or Static DHCP. You will need the device's MAC address, which is a unique identifier for its network card. Find this by going to your device's network settings or by running the command ipconfig /all on Windows or ifconfig on Mac and looking for the "Physical Address" or "HWaddr" line. Enter the MAC address and the IP address you want to reserve, then save.

From that point on, whenever the device connects to your network, your router will assign it that same address automatically. This is safer than setting a fixed address on the device because your router manages it, and there is no risk of conflicts.

Understand address conflicts and how to avoid them

An address conflict happens when two devices have the same internet address on the same network. This usually causes one or both devices to lose connection or behave erratically. It most often occurs when you set a fixed address on a device and that address falls within the range your router is also using for automatic assignment.

To avoid conflicts: if you are setting a fixed address, use a number outside your router's automatic range. If you are using DHCP reservation in your router, the router prevents conflicts automatically. If you suspect a conflict is happening, restart both devices and check your router's connected devices list to see if any address appears twice.

If a conflict persists, restart your router completely. This clears all address assignments and forces devices to request new ones. If one device keeps getting the same address as another, set a fixed address or reservation for one of them to separate them permanently.

Find your current address and your router's address

Before you change anything, you may need to know what address your device currently has and what your router's address is.

On Windows: Open Command Prompt and type ipconfig. Look for "IPv4 Address" (your device's address) and "Default Gateway" (your router's address).

On Mac: Open Terminal and type ifconfig. Look for "inet" (your address) and "router" (your router's address).

On iPhone or iPad: Go to Settings, tap Wi-Fi, find your network, and tap the info icon. Your address appears under "IP Address."

On Android: Go to Settings, tap Wi-Fi, long-press your network, and tap "Manage." Your address appears under "IP address."

When to change your address and when not to

Change your address when a device is not connecting properly and restarting does not fix it, when you are setting up a printer or security camera that needs a stable address, or when you are organizing your network and want devices in a specific order. You might also change it if you are troubleshooting a network problem and need to isolate whether the issue is with a specific address.

Do not change your address if your network is working fine — there is no security benefit to changing it regularly, and unnecessary changes can create conflicts. Do not set a fixed address for a device that moves between networks, like a laptop or phone, because the address will be wrong on other networks. Do not use an address that is already in use or that falls in your router's automatic range, as this creates conflicts.

Frequently Asked Questions

Will changing my internet address affect my internet speed?

No. Your internet address is just a label your router uses to send data to the right device. Changing it does not change how fast data moves or how your device connects to the internet. If you notice slower speeds after a change, the change itself is not the cause — something else on your network probably changed at the same time.

Can I pick any address I want?

No. Home networks use private address ranges that start with 192.168, 10, or 172.16. Within those ranges, you must avoid addresses already in use and addresses your router reserves for automatic assignment. Your router's manual or settings page will tell you which range it uses for automatic addresses.

What is the difference between a fixed address and a reserved address?

A fixed address is set on the device itself and stays the same no matter what network it connects to. A reserved address is set in your router and only applies when the device is on your home network. Reserved addresses are safer because your router prevents conflicts automatically.

Do I need to change my address if my device keeps disconnecting?

Not necessarily. Disconnections are usually caused by weak signal, interference, or router problems, not by the address itself. Try restarting your device and router first. If that does not work, move closer to the router or check for interference from microwaves or cordless phones before changing the address.

What happens if I set a fixed address outside my home network?

The device will not connect to that network because the address does not belong to it. If you travel with a laptop or phone, use automatic addressing (DHCP) so it gets the right address for each network you join. Set fixed addresses only for devices that stay in one place, like printers or cameras.
