TLDR: If you space out the total number of IPv4 address around the equator you get one address every 0.933 Centimeters. If you space out every address available in IPv6 at the same distance you can get 72% to the edge of the observable universe.

I wanted to find a way to put into words, exactly how big the IP space is for IPv6. First I checked google to get the circumference of the earth at the equator. Google says "about 24,902 miles". Then I divided the total number of IPv4 address(4,294,967,296) into that space and got 0.00000579794869 Miles. converted that is roughly 0.933 Centimeters. So if all of the IPs available in IPv4 were spread across the equator evenly there would be one IP address every .933 Centimeters.

The question becomes, using .0933 Centimeters as a yardstick, how far out into space can you get with the number of address available in IPv6 which is 2^128 or

340282366920938463463374607431768211456

we can just shorten that down to 3.4*10^38. Then multiply that number by our yardstick (0.933) to find out how many centimeters IPv6 goes. which is 3.17*10^38

but Centimeters is not a very good way to measure space so let's convert that into lightyears. that is 33,558,027,143.901229858 light years. or 3.35*10^10 light years

The only thing that could relate to that large of a number is the edge of the observable universe.

Most of you know that it takes time for light to travel, so when you look at stars, you are looking at what happened millions or billions of years ago. The farthest you can look back in time is to when the Big Bang happened. since there was no light (or space) before then, that is the boundary. the edge of the observable universe is 46.5 Billion light years away (no matter where you are standing).

IPv6 address spaced out can get you 33.5 Billion light years away, or just over 72% of the way to the edge of the observable universe.
