We have IPS sensors distributed throughout our internal network and we're seeing signature 6065/0 show up between certain DNS servers at certain times. I have the IPS setup to log these packets and it looks like name queries that are failing keep happening again and again for a domain name I don't recognize, but I'm mostly concerned as to why it's being detected as a loop. Is anyone familiar with this type of network behavior? Is anyone else seeing this signature fire very much?
