[Dshield] Ping Problems

Actually, this is likely  a "feature" of Internap.  They use these pings to
measure Internet performance, as part of their own service guarantees and to
ascertain the best path from Point (a) to Point (b).  I have read threads
about this traffic before (maybe not on this list, but somewhere I am sure).
