Update to Telecom Xtra DNS servers
by Ted Grenfell 02 Nov '05

02 Nov '05

As part of our ongoing DNS service improvements, Telecom is making some changes to it's DNS servers which will affect some non-Telecom customers. The following Xtra name servers will in future only accept queries from Non-Telecom customers for domains that the name servers are authoritative for. Recursive queries for other domains (e.g. www.google.com) will no longer work. * dnsh1.xtra.co.nz ( 202.27.184.3 ) also known as alien.xtra.co.nz * dnsh2.xtra.co.nz ( 202.27.184.5 ) also known as terminator.xtra.co.nz We will be phasing in these changes from November 15th over a period of several weeks and you may wish to alert your help desks to check the DNS settings of users having problems after that. Currently Xtra operates the following recursive DNS services: * dnsc1.xtra.co.nz ( 202.27.158.40 ) * dnsc2.xtra.co.nz ( 202.27.156.72 ) We are happy for external people to query those IP's for DNS troubleshooting and similar purposes but they should not be directly configured into machines. Please note these IP's may change from time to time and external access may be limited or withdrawn without prior warning (especially in cases of abuse).

There are stats but we do not have a view on the exact numbers of people who have configured alien and terminator as their DNS. There will be some and they will be impacted in some way from recursion being disabled. Hence the heads up.

"no answers" is the usual "not here" reply (like ns1.ihug.co.nz) And therein lies the problem. For a non Xtra user, that has Xtra DNS servers hard coded, 90% of DNS requests will probably work because Xtra's servers have much of the nz internet namespace in their cache, (or the servers are authorititive) The IP address 202.27.184.3 is a virus, it seems have spread into the configurations of many NZ computers, I think it is one of those "it just works" scenarios and computer technicians have used it as a default fix for many "wierd" DNS issues. Once Xtra disable recursion for non Xtra customers, those same techncians will be challenged with trying to diagnose a very intermittent "page can not be displayed" fault. Ted, if we assume this change is being made because there are a significant number of requests (relative to the size of your user base) coming from non Xtra IP addresses, then we would have to assume that a significant number of users (that have dumb client resolvers) are going to be affected. Are there any statistics available from your name servers on the scale of this issue (Like is it 10% non Xtra requests?) Cheers BG

All IP's mentioned in my previous email are still accepting queries. Nothing has yet been implemented as we wanted to ensure advance notice was given so I'm not sure why you were getting 440's sorry.

Most likely your option 3 Brian. There can be expected that there will be some customers who'se interweb thingy appears to die on them.
