TELSTRA BIGPOND NOT TO BLAME, by Telstra BigPond
The highly anticipated companion to their all time best seller WE'RE NEVER TO BLAME.
I called BigPond again today and managed to get a team leader to dig up this report. An investigation was apparently completed yesterday, by their Network team. Nobody had bothered to call me, because they thought we might all like to wait a few extra days.
Here is the outcome of the investigation (please note Optus is another large Aussie ISP):
***Bigpond DNS analysis - Appears external***
***Customer needs to check their DNS delegation, and why we are sent to a DNS server that does not want to talk to us, and why Optus is sent to a DNS server that works.***
***Optus is being issued with different name servers. Nothing we can do with this. Customer has to deal with their service provider, and get them to fix whatever it is that is sending us to a server that will not respond. The name server we are sent to does not talk to us. ***
Basically, they're saying that they're being sent to ns1 and ns2.dotauserver.com and that this is probably in error. To my knowledge, it is not in error. This is where they should be sent to resolve the names. The problem is, as I advised them originally, that their DNS cannot resolve dotauserver.com.
Full report below. PLEASE NOTE the massie.com.au domain referred to in the report is simply one of our domains that we gave them as an example, for their testing.
JJ OR OTHER DOTABLE TECHS - PLEASE RESPOND HERE AND ALSO FOLLOW UP WITH TELSTRA BIGPOND.
Thanks,

Bigpond DNS analysis - Appears external
When we (BigPond DNS) performed a query for this domain, we are informed that the nameserver that is authorative is
massie.com.au. 14400 IN NS ns2.dotauserver.com.
massie.com.au. 14400 IN NS ns1.dotauserver.com.
;; Received 86 bytes from 156.154.102.18#53(udns3.ausregistry.net.au) in 158 ms
When I use Optus name server, the get returned to name servers
massie.com.au. 86186 IN NS ns29.dotcolo.com.
massie.com.au. 86186 IN NS ns30.dotcolo.com.
Customer needs to check their DNS delegation, and why we are sent to a DNS server that does not want to talk to us, and why Optus is sent to a DNS server that works.
Technical details follows:
=================
When I query ns1 and ns2, I get no answer.

When I query the Name servers that are issued to Optus, I do get an answer.

So the question becomes, why is BigPond being sent to a DNS server that doesn?t work and Optus to a DNS server that does work????
Lets see where the .com.au name servers say. maybe they are out of sync, and it depends which .com.au I hit.
com.au. 259200 IN NS dns1.telstra.net.
com.au. 259200 IN NS au2ld.CSIRO.au.
com.au. 259200 IN NS audns.optus.net.
com.au. 259200 IN NS udns1.ausregistry.net.au.
com.au. 259200 IN NS udns2.ausregistry.net.au.
com.au. 259200 IN NS udns3.ausregistry.net.au.
com.au. 259200 IN NS udns4.ausregistry.net.au.
com.au. 259200 IN NS ns1.audns.net.au.
com.au. 259200 IN NS ns1.ausregistry.net.au.
com.au. 259200 IN NS ns2.ausregistry.net.au.
com.au. 259200 IN NS ns3.melbourneit.com.
Every single one points me to
;; AUTHORITY SECTION:
massie.com.au. 14400 IN NS ns1.dotauserver.com.
massie.com.au. 14400 IN NS ns2.dotauserver.com.
Optus is being issued with different name servers. Nothing we can do with this. Customer has to deal with their service provider, and get them to fix whatever it is that is sending us to a server that will not respond. The name server we are sent to does not talk to us. Our nameserver addresses if it helps.
61.9.133.200
61.9.134.56
61.9.134.72
61.9.188.40
61.9.194.56
61.9.195.193
61.9.207.6
61.9.211.6
61.9.211.40
61.9.226.6
61.9.226.40
61.9.242.6
61.9.242.40
For what it is worth, when I use web based DNS eg:
network-tools.com
www.dnswatch.info
www.zoneedit.com
They all fail to resolve as well, supporting my belief this is external to BigPond.
