## Blocking Websites Using the Hosts File (Windows)
Modifying the hosts file is a more technical but effective way to block websites system-wide on Windows. This method works for all browsers and applications on your computer.
**Important Note:** Editing the hosts file requires administrator privileges. Be careful when making changes, as incorrect modifications can cause network connectivity problems.
1. **Open Notepad as Administrator:**
* Click the Start button.
* Type “notepad” in the search box.
* Right-click on “Notepad” in the search results and select “Run as administrator”.
* Click “Yes” if prompted by User Account Control (UAC).
2. **Open the Hosts File:**
* In Notepad, click “File” > “Open”.
* In the “File name” field, type `C:\Windows\System32\drivers\etc\hosts` and press Enter. Make sure “All Files” is selected in the dropdown menu next to the filename, or Notepad won’t show the hosts file.
3. **Add Website Entries:**
* At the end of the file, add the following lines for each website you want to block:
127.0.0.1 www.example.com
127.0.0.1 example.com
Replace `www.example.com` and `example.com` with the actual domain names you want to block. The `127.0.0.1` is the loopback address, which directs the website request back to your own computer (effectively blocking it).
* It is important to include *both* the `www.` and the non-`www.` version of the site.
* You can add multiple websites to the block list by adding a new line for each website.
4. **Save the Hosts File:**
* Click “File” > “Save”. Make sure it saves as `hosts` with no extension. If Notepad wants to save it as a `.txt` file, make sure to select “All Files” as the file type when saving.
5. **Clear DNS Cache (Optional):**
* Open Command Prompt as administrator (search for “cmd”, right-click, and select “Run as administrator”).
* Type `ipconfig /flushdns` and press Enter. This clears your DNS cache to ensure the changes take effect immediately.
6. **Test the Blocking:**
* Open your web browser and try to visit the blocked website. You should see an error message indicating that the website cannot be reached.
**Example:**
To block Facebook and Twitter, your hosts file might look like this:
# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the host name denoted by a ‘#’ symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
127.0.0.1 www.facebook.com
127.0.0.1 facebook.com
127.0.0.1 www.twitter.com
127.0.0.1 twitter.com
## Blocking Websites Using the Hosts File (macOS)
The process for blocking websites using the hosts file on macOS is very similar to the process on Windows.
**Important Note:** Editing the hosts file requires administrator privileges. Be careful when making changes, as incorrect modifications can cause network connectivity problems.
1. **Open Terminal:**
* Go to Finder > Applications > Utilities > Terminal.
2. **Open the Hosts File:**
* In Terminal, type the following command and press Enter:
sudo nano /etc/hosts
* You will be prompted to enter your administrator password. Type your password and press Enter.
3. **Add Website Entries:**
* At the end of the file, add the following lines for each website you want to block:
127.0.0.1 www.example.com
127.0.0.1 example.com
Replace `www.example.com` and `example.com` with the actual domain names you want to block. The `127.0.0.1` is the loopback address, which directs the website request back to your own computer (effectively blocking it).
* It is important to include *both* the `www.` and the non-`www.` version of the site.
* You can add multiple websites to the block list by adding a new line for each website.
4. **Save the Hosts File:**
* Press `Ctrl + O` to save the file. Press Enter to confirm the file name.
* Press `Ctrl + X` to exit the nano editor.
5. **Clear DNS Cache (Optional):**
* In Terminal, type the following command and press Enter (this command depends on your macOS version. Try the first, and if that doesn’t work, try subsequent ones):
* `sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder` (macOS Sierra and later)
* `sudo discoveryutil mdnsflushcache` (macOS Yosemite and El Capitan)
* `sudo killall -HUP mDNSResponder` (Older versions)
* You will be prompted to enter your administrator password again. Type your password and press Enter.
6. **Test the Blocking:**
* Open your web browser and try to visit the blocked website. You should see an error message indicating that the website cannot be reached.
**Example:**
To block Facebook and Twitter, your hosts file might look like this:
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
127.0.0.1 www.facebook.com
127.0.0.1 facebook.com
127.0.0.1 www.twitter.com
127.0.0.1 twitter.com
## Blocking Websites Using Router Settings
Blocking websites at the router level affects all devices connected to your network. This is a great option for parental control or managing internet access in a small office.
**Note:** The exact steps for accessing your router’s settings and configuring website blocking vary depending on the router manufacturer and model. Consult your router’s manual or the manufacturer’s website for specific instructions. However, the general process is usually similar.
1. **Access Your Router’s Settings:**
* Open a web browser and enter your router’s IP address in the address bar. Common router IP addresses include `192.168.1.1`, `192.168.0.1`, and `10.0.0.1`. If you don’t know your router’s IP address, you can find it using your operating system’s network settings (e.g., `ipconfig` on Windows, `ifconfig` on macOS).
* You will be prompted to enter your router’s username and password. If you haven’t changed them, the default username and password are often printed on a sticker on the router itself. Common default credentials include `admin/admin`, `admin/password`, and `user/user`.
2. **Locate the Website Blocking Feature:**
* Once you’re logged in to your router’s settings, look for a section labeled “Parental Controls”, “Access Control”, “Website Blocking”, “URL Filtering”, or something similar. The location of this feature varies depending on the router.
3. **Add Websites to the Block List:**
* In the website blocking section, you should find an option to add websites to a block list. Enter the URLs of the websites you want to block (e.g., `www.youtube.com`, `youtube.com`). Some routers may allow you to use wildcards (e.g., `*.example.com`) to block all subdomains of a specific domain.
4. **Enable Website Blocking:**
* Make sure the website blocking feature is enabled. There may be a checkbox or switch to turn it on.
5. **Save the Settings:**
* Click “Save”, “Apply”, or a similar button to save your changes. The router may need to reboot for the changes to take effect.
6. **Test the Blocking:**
* Try to visit the blocked website from any device connected to your network. You should see an error message indicating that the website cannot be reached.
**Example:**
On a TP-Link router, you might find the website blocking feature under “Parental Controls” > “Access Control”. You can then add websites to the “Black List” and enable access control to block those websites.
On a Netgear router, you might find the feature under “Security” > “Block Sites”. You can then enter the keywords or domain names you want to block.
