Want faster DNS resolution? Speeding up your internet experience?

I recently found namebench an open-source DNS Benchmark Utility from Google.

Basically you install on your local machine and it scans and suggests the best open DNS servers to use. Very cool!

namebench runs on Mac OS X, Windows, and UNIX, and is available with a graphical user interface as well as a command-line interface.

Some suggested DNS servers to use in South Africa


Google Public DNS Servers


Internet Solutions (ISDSL) ( Cached ) ( Cached )

SAIX / TelkomSA ( Open ) ( Caching only ) ( Open ) ( Caching only ) (DSL / Cached) (DSL / Cached)

  1. Thanks for that Jason.
    Found this article when having problems with Telkom’s DNS – I normally just change to google’s open one, but thought I better check if there are others out there. After running the tool myself (as of April 29th 2016) from a 10mbps ADSL line in Camps Bay, Cape Town, I get:

    IP Descr. Hostname Avg (ms) SAIX Cape Town ZA-2 231.64 DynGuide 261.04 Google Public DNS-2 262.54 UltraDNS 268.07 DataPro-2 ZA 270.25 SAIX Johannesburg ZA 301.61 SAIX Rosebank ZA 332.38 SAIX Pretoria ZA-2 349.28 OpenDNS 356.52 SAIX Cape Town ZA 440.66

    (shockingly slow on average, no?)

    • I have a 3g modem
      How do I configure it

      so that I can use Google DNS server


      • I know its a bit late yakoob but you press the windows key and search for “Network and Sharing Center” once open you check your main connection to the “Internet” then under “Connections” click the option that says “Ethernet” or whatever connection type you have. This will open the status of the connection showing how much data you sent/received. Go to Properties–>Internet Protocol Version 4 (TCP/IPv4) Double click that option, then tick the radio button for “Use the following DNS server addresses” and type in your desired IP address. Google being: and as alternative.
