Jim posted earlier in the week (https://isc.sans.edu/diary.html?storyid=13387) regarding a bind 9 vulnerability.  Whilst possibly unrelated we've had a report regarding a few million DNS responses with static IDs being sent to an organisation.

If you have something similar happening and you are in a position to capture some packets we'd appreciate it if you could upload some for us to have a look at.  Especially of they all have the same ID number.

This doesn't sound like an exploit for CVE-2012-1667 at all. More likely it is the victim end of some variant of the DDoS
amplification attack described at https://isc.sans.edu/diary/DNS+ANY+Request+Cannon+-+Need+More+Packets/13261
