How to block an ip address in your router

This is an example of blocking a device from accessing an ip address so that it can not download information from a specific ip address from the internet. I have a WD LIVE TV streaming media player and it is popping up to update to a firmware, however, after reading from the WD support forums, numerous users complained of so many problems after the firmware update. Most of them have to revert back to the original firmware. To prevent the message from prompting to the device or your smart TV, the ip address of support.wdc.com must be blocked in your router. Here is the procedure below:

How to block an ip address in your router:
   
1. Start
2. Run
3. cmd
4. OK
5. In the command prompt, type the following:
   ping support.wdc.com
6. Note the ip address 129.253.55.56
7. Open internet browser
8. Type 192.168.0.1
9. Press Enter
10. Login to your router
11. Enter your admin password
12. Go to Firewall (or Security) depends on the brand of your network router
13. Click Access Control (or Filter) depends on the brand of your home router
14. On Customer Defined Filtering Table, Add 129.253.55.56
  
    For HTTP: (port 80)
    Name: support.wdc.com
    Type: TCP/UDP
    LAN IPs: single address
    Start IP: 129.253.55.56
    From port: 80
    To port: 80
    Apply

    For HTTPS: (port 443)
    Name: 443support.wdc.com
    Type: TCP/UDP
    LAN IPs: single address
    Start IP: 129.253.55.56
    From port: 443
    To port: 443
    Apply

    Do the same instructions and steps with the other Western Digital ip address 129.253.170.35

14a. On Firewall > URL Blocking:
     Put a check mark on Enable Keyword Blocking
     On Keyword/Domain name, press ADD KEYWORD and type the following keywords:
        support.wdc.com
        http://support.wdc.com
        https://support.wdc.com
        129.253.55.56
        129.253.170.35
        http://129.253.55.56
        https://129.253.55.56
        http://129.253.170.35
        https://129.253.170.35

        Click Apply

After doing all the steps above, you should see the two ip addresses BLOCKED. To check this, open an internet browser and type:

support.wdc.com

your browser should provide a message saying:

This page has been blocked based on your settings
To continue browsing, either use your back button or enter a new web address

The blocked page:

http://support.wdc.com/

matches the following signature:

support.wdc.com
     
     
The router will block support.wdc.com so that your TV and the WD TV LIVE will not update with the new firmware software.
