   I've been a lover of IP addressing for many years, since I was in high school.   
   I always found it funny how IPv4 had so few addresses because of the   
   unexpected take off of the "internet".   
      
   I then started looking in to IPv6 and this was my first foray into mega   
   numbers which lead me down a slippery slope of Googolplexes and Infinity but   
   IPv6 is my first love. Here is some info related to IP addressing (heavily   
   rounded for ease of viewing):   
      
   IPv4 = 2^32   
     4,290,000,000   
     |   |   |   Hundreds   
     |   |   Thousands   
     |   Millions   
     Billions   
      
   IPv6 = 2^128   
   340,000,000,000,000,000,000,000,000,000,000,000,000   
     |   |   |   |   |   |   |   |   |   |   |   |   Hundreds   
     |   |   |   |   |   |   |   |   |   |   |   Thousands   
     |   |   |   |   |   |   |   |   |   |   Millions   
     |   |   |   |   |   |   |   |   |   Billions   
     |   |   |   |   |   |   |   |   Trillions   
     |   |   |   |   |   |   |   Quadrillions   
     |   |   |   |   |   |   Quintillions   
     |   |   |   |   |   Sextillion   
     |   |   |   |   Septillions   
     |   |   |   Octillion   
     |   |   Nonillion   
     |   Decillion   
     Undecillion   
      
      
   Comparison to humans:   
      
   1.1. Estimated population of Earth (~2014)   
   7,210,000,000   
      
   1.2. Average number of molecules in an average human body   
   156,000,000,000,000   
      
   1.3. Average number of atoms in an average human body   
   5,940,000,000,000,000,000,000,000,000   
      
   1.4. Estimated number of atoms in the current human race   
   42,800,000,000,000,000,000,000,000,000,000,000,000   
      
      
   Comparison to things:   
      
   2.1. All the grains of sand on Earth   
   7,500,000,000,000,000,000   
      
   2.2. All the stars in the universe   
   70,000,000,000,000,000,000,000   
      
   2.3. Diameter of the observable universe (in millimetres!!)   
   92,000,000,000,000,000,000,000,000,000

   v6   340,000,000,000,000,000,000,000,000,000,000,000,000   
   1.1                                        7,210,000,000   
   1.2                                  156,000,000,000,000   
   1.3                5,940,000,000,000,000,000,000,000,000   
   1.4   42,800,000,000,000,000,000,000,000,000,000,000,000   
          |           |                   |   |   
          |           Octillions          |   Billions   
          Undecillions                    Trillions   
      
   This means we can give about 7 IPv6 addresses to each atom in the entire human   
   race! Or, you could give each person Earth right now this many IPv6 addresses:   
      
                     47,261,439,850,130,342,147,690,917,698   
                      |   
                      Octillion   
      
      
   Side-by-side comparison to things:   
      
   v6  340,000,000,000,000,000,000,000,000,000,000,000,000   
   2.1   |                       7,500,000,000,000,000,000   
   2.2   |                  70,000,000,000,000,000,000,000   
   2.3   |          92,000,000,000,000,000,000,000,000,000   
         |           |       |   |   
         Undecillions|       |   Quintillions   
                     |       Sextillions   
                      Octillions   
      
   You could therefore give each grain of sand this many IPv6 addresses:   
      
                                45,300,000,000,000,000,000   
                                 |   
                                 Quintillion   
      
   Or even more magnificently, this means you can give every millimetre from one   
   side of the universe to the opposite side of the universe in a straight line   
   about 3.6 billion IPv6 addresses... every... millimetre...   
      
   ...aaaand now my head hurts so I'll leave it there.
