Vodafone New Zealand - access to recursive resolvers
To all members, Vodafone New Zealand will start blocking external access to the recursive DNS servers of the former TelstraClear network to non-customers as of July 3rd 2014. Some of our former customers or other users with Vodafone modems may have the IP addresses of our DNS servers set up on their devices. With that in mind, we'd like to notify you that from midnight 01 July 2014 we will stop providing DNS resolution for external non-Vodafone users, resulting in such customers being unable to browse the internet. The affected DNS servers are at the following IP addresses: 203.97.33.14 203.97.37.14 203.97.78.43 203.97.78.44 Vodafone customers who need help with this change can contact the Vodafone Technical Contact Centre on 0800 438 448. Regards David Robb Transport Design Engineer, Vodafone New Zealand
Good move. Is this by any chance related to the current DNS errors being reported mainly happening with the .43 and .44 servers?

Yes; the servers have for some years now accepted recursive queries from a large chunk of the NZ IP space (but blocked queries from international sources). Unfortunately there are an increasing number of DNS amplification attacks which use open customer resolvers spread across NZ, some of which are outside of the Vodafone customer IP address space, and these attacks have at times caused problems for the nameservers. We are working with our own customers to clean up those open recursive resolvers that we have identified. David Robb Transport Design Engineer, Vodafone New Zealand
