Apparently each region of SA has a different DNS per place like SAIX and IS.

Is this true?

Western Cape's is:

SAIX
196.43.46.190
196.43.34.190

IS
168.210.2.2
196.14.239.2

If it is true, does anyone know a place where I can find the different DNS per region?

Oh, for those interested, it's for a Linux box, now I want to know so that if I send a box up to say, PTA, I have that area's DNS' for whatever backbone we use.

Proper or not, Open DNS works when others fail...

or you might want to try Google:
8.8.8.8
8.8.4.4

Nooooooooooooooo

Why do people still insist on using international recursive DNS resolvers?

There are new CDNs being setup in SA on a monthly basis right now. Up to 50% of the content that you used to view from international websites has become available from local servers over the last year.

Yet people continue to spread mis-information about DNS resolvers which wastes international capacity and pushes up your browsing latency by up to 3000ms....

:(

Well then when your pppoe connection is established , then dns servers are given to your at that time, use them.

Your latency is dependent on your ISP.

The reason for using Intl. DNS servers, like Open DNS is due to the fact that - local cache servers are not updated as frequently - e.g. if you are designing a website or require up to the minute content Open DNS is the only solution...

There are other less important reasons, like blocking adverts (saving bandwidth), Anti-Phishing, Malware Site Protection / Botnet Protection, etc. See: http://www.opendns.com/solutions/overview/

That is actually not true, as well as you perhaps do not know exactly how these CDNs work. Akamai for example, the moment a new file is uploaded, change the URL the file is hosted on, thus once the web page itself is updated to use the new URL, regardless of whether the SA hosted CDN server cached it yet or not, the newer static file will be served. I read this in a document about how Akamai works some time ago, as well as this was at home, if I had the link I would put it here.

But basically it boils down to this, you really don't need international DNS servers to get the most up to date content. Also, you should know whether your website makes use of a CDN or not, as it costs money to make use of them in the 1st place.

Generally using international DNS servers will just slow down your connection because you need to request more content over the slower international links as opposed to local links, where most of these servers run on massive backbone networks in SA.

Say what you want, there really is no reason to use international DNS servers, unless you want to make use of the parental controls that OpenDNS have or if you believe your ISP is playing with your DNS by redirecting you to other sites or whatever or perhaps use the same DNS servers over multiple ISP links whose DNS servers don't work on each other, ie. IS dns servers dont work on the SAIX network or vice versa.
 
Saix had some specific area servers,most of which are decomissioned or reappropriated afaik

IS has 2,dnscache1.is.co.za and dnscache2.is.co.za
