[RndTbl] DoD multicast?

[Trevor Cordes]

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?
