Unlocator is a Smart DNS Proxy. Basically it allows you to unblock content that is locked in your location. For example BBC Iplayer, American Netflix, Canal Plus and the likes. In this performance test I will look at DNS speed numbers of Unlocator, Google DNS, OpenDNS, DynDNS , Ultra DNS and two of Unlocator’s competitors.

Unlocator Performance Review – The Basics

Smart DNS Proxies are in essence DNS servers with a twist. So regardless of their magic in unblocking Netflix and the likes. A Smart DNS provider still has to resolve DNS queries, and it has to do it fast and reliably. Otherwise, all of your Internet activities will suffer as probably most of your Internet and WWW request will start with a DNS request. See the illustration below :


The steps taken each time you do a DNS request are :

  1. You ask your DNS server for the IP of a hostname “Google.com”
  2. The DNS server checks it’s cache
    1. If hostname is in cache it returns cached answer
    2. If hostname is not in cache it gets the result and returns answer
  3. Now your system does have the IP of Google.com and it can send the search request.

So in essence, unless you actually transform a hostname to an IP you are stuck. That is why speed of DNS is essential to the speed of your Internet experience.

To do this test I did use a utility called namebenchQuoting the namebench site “It hunts down the fastest DNS servers available for your computer to use. namebench runs a fair and thorough benchmark using your web browser history, tcpdump output, or standardized datasets in order to provide an individualized recommendation.

Finally, I did do this test from Denmark, results might vary from other global locations, but I guess for all of Europe the results should be similar.
