What does it mean to release and renew your IP address? This article will walk you through how this process works and how to do it in Windows 10.
Why Release & Renew An IP Address?
When your home router connects to the Internet, your Internet Service Provider (ISP) assigns an IP address to your router. This is the only device in your home that can obtain an IP address directly from your ISP. It is also known as your “public IP address”.
Your router then assigns IP addresses to individual devices within the home network on its own subnet. These usually follow a standard convention like 192.168.0.X. The X is assigned randomly, from 1 for the router to 255.
Each device has the option to release and renew its assigned IP address.
- You can let your router release your assigned IP address and get a new one from the ISP.
You can make devices on your network release their assigned IP address and receive a new one from the router.
The release and renewal of an IP address is activated on the device itself and the network management device (router or ISP) automatically assigns a new one.
Why would someone do this? There are many reasons.
- Reconfiguring a router sometimes interrupts the Internet connection of some connected devices, and renewing the IP address on those devices fixes the problem.
- Common Internet connection problems on all computers can often be solved by changing the IP address.
- If a website or forum has blocked your router’s Internet IP address, renewing your router’s IP address will prevent the blocking.
- Releasing and renewing your computer’s IP address can fix many common minor glitches and problems.
Release & Renew IP Address On a Router
Remember that if you tell your router to release your IP address, you will lose your internet connection. And since the router forwards this internet connection to all connected devices, all these devices lose their internet connection as well.
To do this:
- Log into your router as an administrator, using the admin account and password.
- Every router has its own menu system. Find the area that shows the Internet connection status. For example in the Netgear router, select Advanced and then select Connection Status under Internet Port.
- This will open a window showing the current status of the router’s internet connection.
- At the bottom of this window you’ll see the Release and Renew buttons. First, select Release to release the router’s current IP address back to the ISP. At this point, the router will no longer have an active internet connection.
- Select the Renew button to obtain a new IP address for the router from the ISP. You’ll see a new IP Address appear in the window. Once you see this, it means your router is connected to the internet again.
For other router models, you may need to look for the Internet connection status in the WAN or Internet menus, where you will see the Share and Refresh buttons.
If you can’t find it, check your router’s manual or website for more information.
Remember that you can reset your wireless router to factory settings if renewing your router’s IP address does not work.
Release & Renew IP Address On Windows
Whether you are using Windows XP, 7, 8, or 10, the process for releasing or renewing an IP address is the same.
- Launch the command prompt.
- In the command prompt, type ipconfig/release.
- You’ll see a list of messages showing a disconnected status. This is normal and it means your network adapter has lost its connection to the network.
- Still in the command prompt, type ipconfig/renew.
This will cause your network adapter to reach the router and request a new IP address. The router responds by assigning your computer an IP address.
Scroll to the bottom of the message and you should see that your network adapter is now assigned a new IP address.
Now that your computer has a new IP address, you can reconnect to the Internet with your browser and browse the Internet as usual. If the internet still doesn’t work, you may need to restart your computer.
Release & Renew IP Address On Mac
You can also share and renew your IP address on macOS, but instead of using the command prompt, you can do it in the TCP / IP settings.
To do this:
- Select the Apple button and select System Preferences.
- Next Select the Network icon under Internet and Network.
- Select the TCP/IP tab in the Network window.
- On the right side of the window, you’ll see a Renew DHCP Lease button. Select it.
This will release and renew your IP address in one step. Select OK to close the network window. Also exit the System Preferences window.
You may need to restart your Mac to complete the sharing and renewal process.
Release & Renew IP Address On Mobile
Getting a new IP address on your Android is not that easy. You must force your phone to “forget” the current WiFi network it is connected to. As soon as you do this, the current connection (and IP address) will be released. Next time you go online, you will get a new one.
To do this on Android:
- Go into your Android Settings screen.
- Tap Connections.
- Tap Wi-Fi.
- Select the Gear icon to the right of the Wi-Fi network with the Connected status.
- At the bottom of the screen, tap the Forget trash can icon.
This will break the WiFi connection with your router. If you reconnect by reading the WiFi network and logging in with your WiFi network credentials, your Android will receive a new IP address.
Unlocking and renewing an IP address on an iPhone is even easier.
- Launch the Settings app.
- Tap Wi-Fi.
- Next Tap the i icon on the right side of the Wi-Fi network you’re currently connected to.
- Tap Renew Lease. Tap Renew Release again in the pop-up window.
This will free up your iPhone’s IP address on your WiFi network and then renew it.
As you can see, it is very easy to update the IP address of your computer or mobile device on your WiFi network. This is often the first thing to try when you have problems with your network or Internet connection.
