A few of the sites I run do not do any business outside the US, but these look like huge chunks to add in htaccess files, so I am trying to stick to IPs that are actually being abusive. I don't get to use httpd. I am blocking by CIDR, but cringe at the number of lines it takes.
Long ago I blocked myself with generous blocking so I do check "iffy" ranges, that is good advice.
