Reliable Public D.N.S. Servers...
Greetings Listers, Apart from OpenDNS and Google Public D.N.S., which other public D.N.S. servers can I configure my forwarders with?

Is there a real compelling reason why you cannot have your own DNS for your own recursive queries? ./Ok3ch On Fri, Nov 21, 2014 at 1:52 PM, Michael Bullut via skunkworks < skunkworks@lists.my.co.ke> wrote:

You still need to communicate with other DNS servers - which ideally would be close. This brings up a related issue. DNS resolution is one of the biggest problems with Kenyan Internet. The Google/OpenDNS nodes are off-continent and because the traffic is UDP, are highly susceptible to the packet loss problems discussed last week. Having just one major anycast DNS node in East Africa would be a "big deal". Having that node be a primary DNS server for local ISP DHCP configurations would be an even bigger deal. By major I mean one with enough queries that the cache hit ratio is up above 50%. This is more of a problem these days because everybody is using short TTLs for their records ... which means that the cache timeout is low and you need alot of traffic to not be constantly going to authoritative name servers which are far away. -- Kili - Cloud for Africa: kili.io Musings: twitter.com/varud <https://twitter.com/varud> More Musings: varud.com About Adam: www.linkedin.com/in/adamcnelson On Mon, Nov 24, 2014 at 10:15 AM, Okechukwu via skunkworks < skunkworks@lists.my.co.ke> wrote:

In all my working life, I have never come across a situation where I MUST use forwarders, in those situations, views always work for me. ./Ok3ch On Mon, Nov 24, 2014 at 8:29 AM, Adam Nelson <adam@varud.com> wrote:

I suppose Michuki Mwangi did setup one anycast DNS node and it's somewhere at KIXP. Mich - am I dreaming? On 24 November 2014 at 11:05, Okechukwu via skunkworks < skunkworks@lists.my.co.ke> wrote:

I believe what Mich setup was an anycast instance of either J or K root server which is not recursive in nature. On Mon, Dec 8, 2014 at 2:49 PM, Odhiambo Washington via skunkworks < skunkworks@lists.my.co.ke> wrote:
