There's a problem though. There are:
756,494,121 addresses according to addresses_in_order_of_first_appearance.txt.gz
756,524,407 addresses according to addresses_sorted.txt.gz
Obviously, these numbers should be the same. I haven't scheduled automated updates yet, I first want to recreate this data from scratch to see which number is correct.
After recreating this data, I now have
757,437,766 unique addresses (don't click this link unless you want to download 18 GB).
My next step would be to add a few days of data, and count addresses again. Next, I'll recreate all data "from scratch", and see if I end up with the same numbers. I don't know why there's a difference, and I don't like loose ends in my data.
