I am searching for a way to handle the following data and am not sure how to start. I have looked at arrays, hashes, hashes of hashes, . . . but I have not come across what I need (or maybe I have and just don't know it). Here is what I have.

IP_Address = domain_1 = seconds
                      = seconds
                      = seconds
           = domain_2 = seconds
                      = seconds
           = domain_3 = seconds
                      = seconds
                      = seconds

I hope this data makes sense as I couldn't think of any other way to present it. I am comfortable working with arrays and hashes so it would be great if this could be handled with one or the other, or maybe a combination of both. If not, how could I go about handling this data? Note that the data is being read from a file but I need to manipulate it without creating another file.

Thanks much in advance!
