How to Block Unwanted Site From Your Router? (Step-by-Step Instructions)

There are many ways to block an unwanted website from your router. You could spend some money to buy any of those internet monitoring programs largely available in the market. But you’d be surprised that some free programs or methods serve as good as the paid ones.

Although paid services offer little configuring and are very easy to use (you merely need to tap once, and it runs) and also provide more than basic functions, a free program is adequate to get the job done.  

Let’s dive into a couple of free methods that can best block unwanted sites.

How to Block Unwanted Site From Your Router

Using your Router

You can use your router’s blocking function to block unwanted sites of your choice or all sites that are not encrypted. Here are the steps:

  • You can find a few ways to discover your Router’s IP address. One of the easiest methods is to right-click the Windows Icon and choose Windows PowerShell (or Cmd Prompt). Type “ipconfig” in the Command Prompt, and you can see some information. The router’s IP address is at the Default Gateway.  

Default Gateway

  • Open up your internet browser and type the IP address on the address bar. Then, log in by entering the username and password.
  • Go to the Firewall or Security Section, and find the URL Filtering or Blocking function.
  • Type in the unwanted website’s URL that you want to block.

Using OpenDNS

You can also block websites using OpenDNS. Even a free version can stop users from visiting the websites. Stick to the steps below to configure the settings:

  • Open up your internet browser and type the IP address on the address bar. Then log in by entering the username and password.
  • Under the Basic Setup page, look for the internet or WAN section.
  • You need to disable auto DNS and enter IP addresses for the OpenDNS servers. So, head on to disable automatic DNS.
  • Type in the OpenDNS server addresses in the two fields: 208.67.222.222 and 208.67.220.220

  • Click Save or Apply button to apply the blocking function. Your router will reboot in about a minute.
  • Next, you have to log in to the OpenDNS dashboard using your new account. You will come to the OpenDNS dashboard.
  • OpenDNS will send an email message that you need to confirm before visiting its website. Go to Settings and type your network IP on the “Add a network” column. OpenDNS will identify your network’s IP address (your public IP) and block unwanted websites you want to go through. 
  • Go to Settings and find the Web Content Filtering to identify unwanted website URLs that you want to block from your network.
  • You have choices to set the filtering security levels – Low, Moderate, High, and Custom. 

Web Content Filtering

  • On the “Manage individual domains” list, add those websites you wish to block (limited to 25 websites). Ensure you check the “Always block” button on every website.”
  • The new settings will only take effect after you flush the cache of your DNS. Although it will automatically set up on your network devices after a while, you can always set it up manually for immediate blocking application. Do the followings:

In Windows operating system – Press the Windows key and the ‘r’ key at the same time. Typing ipconfig / flushdns will flush your DNS. Test the filtering function when it’s done by visiting the intended website and seeing it works.

On the other hand, on Mac, you need to open the Terminal from the Utilities page. Typing dscacheutil -flushcache will flush your DNS, then type sudo killall -HUP mDNSResponder for the DNS service to restart. Enter the admin password when prompted.

Alternatively, you should also delete cache and cookies in your browser. 

  • Try out the settings by trying to visit the unwanted website using one of your connected devices
