#Plan:

#Create a program where it will receive a string of data
#That string will be added to a dictionary, with the ip attributes as its keys
#simulate a filter. Like give it a shell script input with one of the attributes
#And have it present the thingies...
#check in Julios visualization what is presented when filtered
