On a related note, how are you actually getting this data?

What you have said previously ( Number of unique IPs that spoofed a packet
to me. (eg: I sent a packet to 1.2.3.4 and 5.6.7.8 responded). ) doesn't
even make sense.

Oops, I pulled the wrong data (off by one column) out before a trip and
didn't realize it until now.

This is not the spoofer list, but the list of ASNs with open resolvers.

Let me reprocess it.

Apologies, corrected data being generated.
