Hi Brian, ns1 and ns2 are strictly recursive servers. There is no delegation at all. However alien and terminator are still recursive resolvers and authoritative name servers. I fully understand that this causes issues for people so I will take the opportunity to remind people that our open resolvers are: dnsc1.xtra.co.nz 202.27.158.40 dnsc2.xtra.co.nz 202.27.156.72 Where possible I would strongly suggest that people no longer use alien or terminator for recursion for the reasons you give and a few others. PS. Please don't flame me for the open nature of the resolvers I am working on it:) Regards Paul Tinson Senior Specialist Level 9, Mayoral Dr Bldg, 31 Airedale Street Auckland www.telecom.co.nz ________________________________ This communication, including any attachments, is confidential.

Telecom would like to announce our new recursive name servers. This will mean recursive traffic will start to be seen from the following IP addresses:
219.88.186.149 219.88.186.150 219.88.187.149 219.88.187.150
However the IP address's of the new servers are as follows:
ns1.xtra.co.nz 122.56.237.1 ns2.xtra.co.nz 210.55.111.1
Hi Paul A big issue (for the rest of us) in Xtra's topology has been that alien.xtra.co.nz and terminator.xtra.co.nz acted as recursive resolvers and also authoritative servers; this created two separate views of the name space which were frequently different. Will this upgrade solve this issue (i.e. no zone files on ns1.xtra.co.nz and no delegation to those servers from above etc)? Cheers Brian
