Did you use OpenDNS

Are there any drawbacks to using OpenDNS?

I live in Istanbul and many websites are banned by the government here. In order to be able to enter blocked websites like YouTube, some of my friends use a specific DNS server address instead of getting the DNS server address automatically. That way they can bypass the ban. The addresses are as follows:

Preferred DNS server:
Alternative DNS server:

My question is, if I change my mindset like this, will I have any downsides?


These are OpenDNS nameservers, a US-based company that makes money by placing ads and selling data. So you have two disadvantages:

  • The data about your internet usage will be passed on to the US police and not to the Turkish police. It is also sold to US companies.
  • You will be redirected to ad sites if you make a typo in a web address, even if the parent domain exists.

Apart from a slightly higher latency due to longer DNS round trips, actually not. OpenDNS administrators may see traffic spikes and block you if this "trick" becomes too popular.

However, using different DNS servers does not prevent your internet usage from being logged for later law enforcement purposes or from being blocked by a firewall.

I admit that using OpenDNS is not the most recommended method for privacy reasons. However, they can sometimes be very useful for reviewing the changes made to records in a zone file. I am also sure that OpenDNS logs a lot of information about your requests and creates statistical data that they can resell. However, since I was having problems with my ISP DNS servers, I had no choice but to switch to a different DNS server. I chose OpenDNS and have not had an internet outage since then due to DNS errors from my ISP. I admin, there may be other alternative solutions to this.

Also keep in mind that using a different DNS server can cause delays in the first connection, as the first DNS server to be contacted can be reached from a remote location, while the one from your local ISP is likely only two hops away.

However, if you're brave enough to change your settings, you can designate OpenDNS or other third-party DNS as your secondary DNS server.
