Those show the unique ips that visit the forum. I recently changed the calculation for all time to it doesn't count all the ips. Thats why all time shows less than month.

You can reset it by doing.

redis-cli 
del ip:recent

or if you are using mongodb

mongo
db.objects.remove({"_key":"ip:recent"});
