Topic # 84255 27-May-2011 14:03 Send private message

Just read this from the NOG list:

This message is to inform you that TelstraClear will be making changes to its recursive DNS service for broadband and dialup customers.

As part of TelstraClear's ongoing network improvements, we are deploying the following enhancements:

--- Current recursive DNS servers to be replaced by multiple geographically diverse DNS clusters;
--- Anycast routing to be implemented to direct traffic to the nearest DNS cluster;
--- Native IPv6 transport implemented for recursive DNS service;
--- Recursive DNS queries will only be accepted from TelstraClear broadband and dialup customers.

TelstraClear is currently allowing some non-TelstraClear New Zealand IP address blocks to access the following recursive DNS servers:

--- 203.97.78.43
--- 203.97.78.44

Once we have deployed the above enhancements, only queries from TelstraClear broadband and dialup customers will be accepted to the TelstraClear recursive DNS servers. If you are currently using the above name servers, and are on non-TelstraClear IP address space, you will need to change your DNS configuration to use alternative name servers.

Nice. I wonder if that means IP6 support is on the way?

Brilliant I have been having a few issues with DNS recently, I even rang telstra and asked if there was another DNS server I could try...with a helpful no.. I should have come to Geekzone 1st, has sorted all the issues !!

Hmm. I've been unable to access many sites in the .gov domain for some months. I cannot ping them. e.g. www.nhc.noaa.gov have no DNS entry, but whitehouse.gov does. They work fine when I connect via Vodafone 3G and from work. Time for me to contact TC I think ...

Update - just spotted the post about using 203.97.78.43 and .44 for DNS. Fixed!

Not the first time I've been caught by a change. On several occasions I've suggested to the support people that they know our email addresses, so couldn't they send us a message when there's a change to recommended settings or an issue? The best I've ever got was "I'll raise it at our next team meeting", but it does stagger me that NZ telcos communicate so badly.

About 99% of people don't know what dns servers are, and if you email out information advising them to change their dns servers you need to accommodate precise directions for all operating systems, including all possible problems that may arise if they make one mistake such as accidentally updating their ipv6 configuration instead of ipv4 on windows 7/vista, or making a typo error on the primary DNS resulting in a browsing problem, it could generate thousands of additional calls to the call center.

Also 99% of people would call after receiving an email about this just too make sure they were changing the right settings or asking why they need to change this.

Joe Bloggs average would likely have their modem/router set to obtain the DNS servers automatically so no notice is needed to general/home end users most of the time.  I agree it would just lead to confusion.

The message from TCL that Maurcio re-posted was to the NZNOG group not the general public, it's of interest to geeks and network operators.

If you're a geek and change your DNS settings manually you have to take the responsibility for ensuring they are correct.

TelstraClear configuration *IS MANUAL*. The technician will set the PC or router when installing it, but if the user changes equipment is their responsibility to update correctly.

The TelstraClear network does not set DNS automatically.

Really cable is still manual? Didn't know that. I'm sure DSL from Telstraclear was automatic like every other ISP back when we were using Telstraclear at home.

The TelstraClear instructions for cable broadband are here: https://telstraclear.custhelp.com/app/answers/detail/a_id/1306/related/1

A little bit confusing because I have a Paradise email address and was using the .4/.12 DNS addresses, but one thing's for sure - switching to the Clearnet addresses has allowed me to access quite a number of sites that I couldn't before.

Have noticed a drop in connection speed when I changed my DNS servers to the ones in the first post, so have put them back to what they use to be.

Hi all,
I'm in Dunedin on Telstra Clear ADSL.
So after the net disappeared 2 weeks ago but Skype was still ok DNS seemed to be the reason - scanned the posts at Geekzone on the phone and yee haa up and running using the DNS servers above.

I have the Dynalink RTA1320V6 modem running through a TP Link WR1043ND router.  

I followed this to get it running in half-bridge mode, http://www.ben.geek.nz/2006/11/adsl-routing-solution-in-detail/ .  So for 6 months it's been running fine.

The problem is I would rather have the DNS setting in the modem than each PC having to be configured.  With the netbook I don't want to have to clear to use in town, then re-enter the DNS to use at home....ALSO the iPHONE won't work at the mo on WIFI at home...is there a DNS setting in the iPHONE to change?  I tried with no luck.

The crazy thing is that I changed the modems IP address to 192.168.1.8 and the router is on .1.1  - now I cant get into the modem.....am 99% sure it is .8 but I cant access it.....any ideas?

I don't want to reset the modem to be able to get into it in case the half-bridge doesn't work again....well that will be last resort IF I can change DNS setting in the modem, otherwise I'd rather leave it alone.

Thanks for reading :)  I'd really appreciate any advice.
Cheers.

99% of people would have their router give out DHCP leases, which will also typically hand out the DNS servers. The only scenario where you would need to enter DNS servers manually is when you're using static IP's.

Many routers also have a DNSmasq capability where they can be used as the local DNS server.
