can done way:

if go step step, above used line of code quite self-explanatory. here:

ip.split(".") # splitting string on `.` have array #=> ["208", "68", "38", "12"] ip.split(".")[0...-1] # taking 0th n-1 th element of array (-1 represents last element when size unknown) #=> ["208", "68", "38"] ip.split(".")[0...-1].join(".") # joining array on `.` #=> "208.68.38"
