Good afternoon NZNOG, I am a TelstraClear cable customer and have been running Netalzyrhttp://netalyzr.icsi.berkeley.edu/index.html every so often to test various properties of my connection. Recently it has reported that there is a DNS anomaly for www.google.comhttp://www.google.com and partner.googleadservices.com, which resolve to 203.97.30.147 and 203.97.30.149 respectively. Both of these IP addresses are within the TelstraClear block. What is interesting is that when I query the Google DNS servers directly they report the same IP addresses. Can I conclude that there is some sort of Google CDN node in the TelstraClear network? Neil Ramsay
