Changing the default ISP DNS to OpenDNS is the free and easy way to increase the Internet speed, especially when you’re stuck with turtle-speed connection. Beyond that, OpenDNS also provides a better protection against phishing scam to secure your connection. Any drawbacks? As far as I’m concerned, there is no serious drawback worth a mention though.

How OpenDNS Increases the Internet Speed?

One of the factor that contributes to Internet speed is DNS resolving speed. Each time we type a web address at the browser, the address will be sent to a DNS for processing. The DNS will convert the human-readable address to a unique computer-readable IP address, and then only the browser starts transferring the data from the website. A slow response ISP DNS could be the reason having slow connection.

Unlike other unreliable DNS, OpenDNS is fast and stores IP addresses of millions website in its cache. In other words, if you visit a site that has been previously visited by another OpenDNS users, you can get instant fetch and thus increase the overall internet speed. Additionally, OpenDNS has 12 powerful datacenters strategically distributed around the globe to ensure optimal data fetching. The nearer to the datacenter, the faster speed you’ll get.

How to setup OpenDNS on router or modem?

In fact, there are 3 different ways to setup the OpenDNS. The best-performance method is to configure the DNS setting on the router or modem instead of individual PC. This is to ensure all the clients at the particular network will enjoy the privilege of OpenDNS and save the hassle work of setting up at each individual PC.

1. Most of the cases, you can access to your router by typing 192.168.0.1 at the browser address bar. If this doesn’t work, then you need to find your default gateway IP address by typing “ipconfig” at the command prompt. (Start > Run > cmd > type in “ipconfig” > look for default gateway address > copy and paste the address to any browser address bar)

2. After successful login to the router with your username and password, try to look for the DNS tab. Different model of router may have different path, but normally it is within ‘Advanced’. Refer to the router manual in case you couldn’t find it. I’ll be using DSL-2640B as the example:

3. Change the ‘Preferred DNS server’ and ‘Alternate DNS server’ to the following IP addresses. Before that please write down your current settings before changing, just in case you want to change it back (For fixed IP address only).

OpenDNS server addresses:

208.67.222.222
208.67.220.220

Please take note that you can use either OpenDNS server address for both ‘Preferred Server’ and ‘Alternate Server’, but never use the same addresses for both.

4. Press the ‘Apply/Save’ button and wait for the new configuration to set up.

5. Flush the DNS using command prompt. (Start > Run > cmd > type in “ipconfig /flushdns” > Enter)

6. Restart the client computer, router or modem. It’s done and you’re now browsing the internet with OpenDNS!

How to check if the OpenDNS setup is successful?

1. Type “www.facebook.co” at the browser address bar and press enter. The address should be auto-corrected to “www.facebook.com” and you’ll be redirected to Facebook website if the setup is successful.

2. Visit this ‘Test Page’, and you should see a warm welcoming page from OpenDNS.

3. Visit this ‘Phishing Site’ and you should be blocked by OpenDNS.

Conclusion

We don’t recommend to change your current DNS to OpenDNS if the internet connection is already fast. However, you can really see a significant improvement in internet speed if your current internet is slow and especially you’re near to the datacenter.
