It’s worth noting the full number isn’t just the six digits (plus checksum) but the full number including the letters that indicate owner and type, so a single owner wouldn’t give two of their containers the same number. That said, how many containers is one company likely to own? 1,000,000 is a big number but it seems like some of the big logistics companies could flirt with that. Doors anyone know if they have multiple “owner codes” or an I just way overriding the scale here?

  Right. So what happens when we face container number exhaustion and we found out that some C developers have been using char id[12]?

    I suspect they’ll move to Container.v6 and that everyone will dislike because the values are harder to read to say… then the industry will take an additional decade or two to actually start to use it.

      We are approaching decade 3 of ipv6 and ipv4 is still the majority of internet traffic.

        Being a bit more kind, ipv6 only really started to get moving in the wild around ~2010 so we are at the start of the second decade. It has climbed steadily since this point and will be the majority globally within a couple of years. It is already the majority of traffic in the USA, Germany, France and India.

Maersk has a capacity to ship 4 million containers at once. I suspect you’d generally have 3-4x that many because they spend a lot of time waiting around and also just pile up in Los Angeles because no one needs to ship (as much) stuff back to China.
