Starting Feb 4 I've been receiving on my Shaw modem connection an IP protocol 2 (IGMP) packet to 224.0.0.1 (all hosts multicast) from 22.34.128.1 (US DoD!!) every 1 minute on the dot. I've gotten over 10,000 so far. My iptables DROPs them all, but I'm wondering WTF? Is something misconfigured on the net with the DoD or Shaw or am I being targeted by DoD for some reason?
