Blocking an IP address on Windows 10 is a straightforward task that can help protect your computer from unwanted connections. By following a few simple steps, you can effectively block any IP address from communicating with your system using built-in Windows features. This guide will walk you through the process.
How to Block an IP Address on Windows 10
Blocking an IP address on Windows 10 involves creating a new rule in the Windows Firewall. This guide will go through each step to help you successfully block an IP address.
Step 1: Open Control Panel
First, open the Control Panel from the Start menu.
To find the Control Panel, simply click on the Start button and type “Control Panel” in the search bar. Then, click on the Control Panel app when it appears in the search results.
Step 2: Navigate to Windows Defender Firewall
Next, go to System and Security, then click on Windows Defender Firewall.
In the Control Panel, you’ll see various options. Click on System and Security, and then find and click on Windows Defender Firewall. This is where you’ll set up the rules to block an IP address.
Step 3: Advanced Settings
Open Advanced Settings from the left-hand menu.
Once you’re in the Windows Defender Firewall menu, you’ll see an option on the left side called Advanced Settings. Click on it to open the Windows Defender Firewall with Advanced Security window.
Step 4: Create a New Rule
Click on Inbound Rules, then select New Rule.
In the Advanced Security window, you’ll find Inbound Rules on the left. Click on it, then look to the right side of the window for the New Rule option. This is where you’ll begin setting up the rule to block the IP address.
Step 5: Choose Custom Rule
Choose Custom from the rule type options, then click Next.
After clicking New Rule, a New Inbound Rule Wizard will open. Select Custom from the list of rule types and then click Next to proceed.
Step 6: Specify Protocol and Ports
Select All Programs, then click Next until you reach the IP Address screen.
In the Custom rule settings, choose All Programs for the program type, and then continue clicking Next until you reach the section where you can specify the IP addresses.
Step 7: Block the IP Address
Select These IP addresses, then add the IP address you want to block, and click Next.
Under the Which remote IP addresses does this rule apply to? section, choose These IP addresses. Click Add and input the IP address you want to block. After adding the IP address, click Next to proceed.
Step 8: Choose Block the Connection
Select Block the connection, and click Next.
You’ll be asked what action to take when the specified IP address attempts to connect. Choose Block the connection, then click Next.
Step 9: Apply to All Profiles
Ensure Domain, Private, and Public are checked, then click Next.
In the Profile section, ensure that Domain, Private, and Public options are all checked. This ensures that the rule applies to all network profiles. Click Next to continue.
Step 10: Name the Rule
Give your rule a name and click Finish.
Finally, name your rule something descriptive like “Block IP Address X” and then click Finish. Your rule is now active and the specified IP address is blocked.
After completing these steps, the IP address you specified will be blocked from accessing your computer. This helps improve security by preventing unwanted connections.
