I'm still getting notices from my router that IP address 18.104.22.168 is trying to find its way into my network. Each attempt consists of five different DoS attacks (and, no, I don't really have a good grasp on this stuff). These attacks are fairly regular, usually coming after a 5 or 6 hour interval and always at the start of the hour.
I don't have a static IP address - my address has changed three times since these attacks started. I don't think I'm being singled out and I doubt these attacks have anything to do with the department of defense, but they are something between a curiosity and a concern.
I'm also getting single, less frequent probes from IP address 22.214.171.124, which is supposedly a Halliburton address.
