Over the last few weeks the New Zealand Registry Service (NZRS), has been working on the changes required to replace the .nz name server operated by TelstraClear (NS4.DNS.NET.NZ) with a new server operated and managed by the NZRS. The changes for the replacement server are now complete and the new server is in operation. The new IP address for NS4 has been made to the root servers by IANA. There is no impact on the .nz DNS as a result of the change. The new IP address for NS4.DNS.NET.NZ is 202.46.189.130. The new name server uses a technology called ‘anycast’ (http://en.wikipedia.org/wiki/Anycast) and will enable NZRS to add additional servers to other parts of the network if required. It will also lead to greater reporting and monitoring of the .nz name servers. This change is one of several that NZRS is undertaking as part of a project to make improvements to the .nz DNS infrastructure. Dave Baker .nz Registry Services (NZRS) support(a)nzrs.net.nz
