How-to : Bypass Blocked Websites
Back in 2011, i wrote an article about bypassing restricted websites by changing the DNS. I'm pretty sure it accidentally deleted in one of those cleanup session on Blogspot. So i took the liberty to revive the same post so we all can enjoy the freedom of technology. No pun intended.
Note : This will improve your browsing speed as well comparing to standard DNS assigned by ISP.
To explain it simple, let me quote from Wikipedia :
Domain Name System is that it serves as the phone book for the Internet by translating human-friendly computer hostnames into IP addresses
For example, the domain name www.example.com translates to the addresses 184.108.40.206 (IPv4) and 2606:2800:220:6d:26bf:1447:1097:aa7 (IPv6). Unlike a phone book, the DNS can be quickly updated, allowing a service's location on the network to change without affecting the end users, who continue to use the same host name.
Since most of those restricted websites aren't accessible due to the address was blacklisted by local DNS (read : phone book), we need to bypass this old school (and slow to response) DNS and use another DNS that will open the address (and way faster) for us.
With Windows has majority users (according to my Google Analytics) visiting this blog, i am going to use Windows 7 as a guideline here. If you're on OS X, look for Network under System Preferences. Its not that hard to figure it out. Linux user, if you still need a guide, i'd highly suggest you to scrap out Linux from your system.
1. Click Start > Control Panel.
2. Click Network and Sharing Center.
3. Click Change adapter settings.
4. You will notice few adapters here. Identify which one in use, right click on that adapter and click Properties.
5. You will see a list of items for that adapter. Since we're connecting to internet using standard TCP/IP protocol, click Internet Protocol Version 4 (TCP/IPv4) to select it and click Properties.
Alternatively, you can use another 3rd-party DNS like OpenDNS.
6. You will notice another window show up just like above. Click Use the following DNS server addresses to enable custom input so we change the default DNS to third-party.
7. I'd be using Google DNS since its very easy to remember. Those people at Google doing an incredible job making their DNS open and fast around the world. To use their great DNS service, just enter this address 220.127.116.11 into preferred DNS server (do remember each number for each boxes) and 18.104.22.168 as Alternate DNS server.
8. Click OK to save and restart your computer. Alternatively, you can use Command Prompt to flush the DNS resolver by typing ipconfig /flushdns.
9. Bonus : IPv6 as well.
Maybe you wanna write that down.
You should be able to access those blacklisted sites now. Last but not least, most websites would load quicker than before. If you're unable to browse after changing the DNS, use point 6 to revert back to Obtain DNS server addresses automatically and try using another third-party DNS that didn't get blocked by your network administrator.
That's it. If you have a wonderful experience from this guide, do email me for a thank note.
