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
Side-by-side comparison to humans:
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.
