Analyzing SSH Brute Force Attempts

I've been using SSH Guard for years to block brute force SSH login attempts against my home network's gateway and have been logging connection attempts to a database. 1195 unique hosts have been tracked (since the last time the database was cleared).

Informal analysis in the past has shown some pretty ridiculous traffic, whole netblocks have systematically attempted logins. Moving to the next sequential IP address when the current one was blocked (not even switching randomly to a new one).
