Great writeup, but I did have a little chuckle reading "it was taken about near here", followed by coordinates precise enough to identify a single atom. https://xkcd.com/2170/ https://xkcd.com/2170/
- vardump 2y agoGoing to be a different atom once you walk near. Or temperature changes, the wind blows, and so on. We’ll need to give each atom a unique ID. That would solve the problem.

- Aerroon 2y agoThere are 10^80 atoms in the universe, therefore 266 bits are enough to give each a unique identifier. Due to how computers work maybe we can do two numbers: a 32-bit type or area code and a 256-bit counter. Or perhaps we just combine them into a single 272 or 288 or 320-bit number.

- wongarsu 2y agoEarth has about 2^170 atoms. If we ignore the core and mantle, focusing on the crust, surface and atmosphere, we should be able to cram it into IPv6. Even if we add a couple planets and moons in the future. At least if we stop giving each person 18 quintillion IPs just because we once thought encoding MAC addresses in the lower 64 bits was a good idea.
- astrange 2y agoAddressing isn't really the big issue with IPv6. The main issue is that moving to mobile networks means all its assumptions about how routing will work are wrong, since you don't want to lose IP connections when you move across cell towers.

- tim333 2y agoYou're going to run into problems with quantum mechanics and the non zero amplitude that two identical hydrogens swap place.
- tim333 2y agoI'm not sure it's quite enough. By my calculation a change of one in the last digit corresponds to a move of about 1 nm. A water molecule is about 0.27nm across. I think you'd need at least one more digit.
