Blocking IP ranges in .htaccess

I want to block these 3 ranges … - - -

These ranges are all showing as belonging to Facebook. ( electronic stalking )

How do I do this in .htaccess please ?

I’m not sure if there’s any easy way to block those as three specific ranges. I think you might have to block 66.220.144.*, 66.220.145.*, 66.220.146.*, etc.
