#   Write a program that prompts a user for an IP address,     #
#   then checks if the IP address is valid, and then converts  #
#   the IP address to binary (dotted decimal format). Re-use   #
#   the functions created in exercises 3 and 4 ('import' the   #
#   functions into your new program).                          #
#                                                              #
