In a /3 there are 35.184.372.088.832 /48s

if we underestimate the utilization to the 50%, that get’s us to half: 17.592.186.044.416 /48s

If the population gets to 34.359.738.368 people (not sure if that will fit in the earth), and we estimate that every human will live 100 years, and after that we don’t recover every /48, then with a single IPv6 /3, we will have a total IPv6 life-span of 51.200 years.

If we use the rest of the /3s, then we get up to 409.600 years.

And to be honest, I don’t think it makes sense to bury each /48 when a human pass away, same I don’t think that we should calculate it per human instead of householder, but I prefer to be pessimistic in terms of lifetime.

Regards,
Jordi
