Below is information on what DNS is and how we configure it
Domain Name System is like a phone book. It is how the internet converts names such as leaptel.com.au into an IP address to make it easy for you to navigate the internet using easy to remember names.
The reason you should use our DNS servers rather than a third party DNS server is because ours will provide you with a more optimised response than a third party.
Lets say that you are accessing facebook.com. Your computer talks to your local dns server (assume Leaptel), Leaptel then proceeds to lookup. Eventually facebook's dns server responds and based on its internal mechanisms it determine the best ip address for facebook.
What I have seen is facebook use the source ip (which in this case is Leaptel's dns server) to determine the closest and based on their own algorithm it should hopefully return the ideal cache. If you use a third party, facebook would optimise the response based on connectivity of that dns server you are using and we have seen on some occasions facebook was returning a Singapore IP so you would lookup facebook, it would route via NSW IX and up inside facebooks network and into Singapore. Adding delay to the web requests.
This kind of thing can happen fairly often with larger Content Delivery Networks who optimised and route based off DNS initially to distribute requests to the closet network point.
Our dns servers are state based, we have one in VIC, NSW, QLD, SA and WA We set the primary dns we return to be the local cache and then the secondary to be the one one state over. So when dns based path selection is being done by providers you should get directed to the closest cache.
No, when you connect up we provide the DNS servers best for you to use inside the PPPoE connection or the DHCP packet. Your router will receive them. It should then be using them and passing them out to your devices on your local network.
By statically assigning them on your devices, if we make a change (which we do now and again) you may end up with incorrect information.
Currently we assign:
|Customers in:||Primary Server||Secondary Server|
Our DNS servers are set to lookup the DNSSEC values and return to you the DNSSEC response. We don't filter out invalid responses at this stage but we do return to you if it is valid so you can make the choice if you wish to use that response or not.
