Country stats for last year of data

For these country-level stats, the most recent test from each client address is examined within aggregated IP blocks (/24 for IPv4 and /40 for IPv6). If the most recent test in an IP block shows spoofing, the IP block is considered to allow spoofing. If ALL clients indicate blocking, the IP block is considered to block spoofing. (It is considered NAT blocking if there are no non-NAT tests found.) If some clients showed spoofing but the most recent tests show blocking (and there's no evidence of a change in blocking policy), then the IP block is considered "inconsistent". On the map, inconsistent results are counted as spoofing for simplicity.
