Hello to the list!

I have the following code which prints the ip's from fail2ban.log and puts then in an array:

- --------------------------
class ReadIPs
  attr_accessor :ip
  def initialize(ip)
    @ip = ip
  end
  
  def ip(filename) 
    ips = []
    File.read(filename).lines.to_a.each do |place|
      sf = 0
      while sfn = place.index(/(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)/,sf)
        sf = sfn + 3
        ips << $&
      end
    end
      return ips
  end
end

# print methods

a = ReadIPs.new("/Users/atma/Projects/ZoneReport/log/fail2ban.log")
puts a.ip("/Users/atma/Projects/ZoneReport/log/fail2ban.log")

- ---------------------------------

What I don't understand is why do I need to give the argument to the new instance of ReadIPs.new class. In my view the code should look like:

a = ReadIPs.new
puts a.ip("/Users/atma/Projects/ZoneReport/log/fail2ban.log")
- ----------------------------------

But this returns an error and does not run. Can someone please drop a few light here please :-)

best regards & thanks in advance
