That's Interesting, Does anyone have any ideas/clues as to what's causing this continued spike of traffic? Did everyone just switch on v6 for their DNS servers?
What we observed was a sudden change in the number of queries coming from 6 sources:
2001:4400:0:86:f24d:a2ff:fe02:7569 2001:4400:0:86:f24d:a2ff:fe02:7413 2001:4400:0:86:f24d:a2ff:fe03:571d 2001:4400:0:86:f24d:a2ff:fe03:448d 2001:4400:0:86:f24d:a2ff:fe03:57d1 2001:4400:0:86:f24d:a2ff:fe03:1f13
All of them belong to TelstraClear. My bet is they activated those addresses in some of their caching resolvers. Anyone from TelstraClear want to comment on it?
Hi, Yes, those are (almost, see below) the EUI-64 addresses that the new caching resolvers have acquired for themselves. They've got static addresses as well, and I'll look at disabling the autoconfiguration if it's a problem. The addresses above don't quite match however, for the Wellington and Christchurch ones, there should be a change in the third section.. They should be as follows: 2001:4400:0:86:f24d:a2ff:fe02:7569 2001:4400:0:86:f24d:a2ff:fe02:7413 2001:4400:1:86:f24d:a2ff:fe03:448d 2001:4400:1:86:f24d:a2ff:fe03:571d 2001:4400:2:86:f24d:a2ff:fe03:1f13 2001:4400:2:86:f24d:a2ff:fe03:57d1 (Note the :1: and :2:) Obviously being EUI-64 addresses, these will change if the hardware ever gets swapped, so don't anyone go configuring these addresses as their resolvers! --David
