Dir.mkdir("virt_hosts")

255.times do |count|
  filename = "virt_hosts/virt_host_#{count}.conf"
  ip_address = "#{range}#{count}"
  file_contents = contents % {:ip_address => ip_address, :port => (base+count)}
  File.open(filename, 'w') { |file| file.write(file_contents) }
end

This works with:

httpd   2.4.6-67.el7_4.6
mod_ssl 1:2.4.6-67.el7_4.6
