surprising there’s no china, with billions of connected devices. Maybe you don’t need many public ipv4 when you run a country-wide LAN with limited internet access
Country-wide LAN
That is, by definition, a WAN.
Now I wonder if the network of Vatican City is considered a WAN. Because there are likely companies with LANs larger than that.
This document suggests that some of our home labs might be bigger than Vatican City’s telecom network. (note: attempt at humor)
I’ve found a couple of articles ostensibly about Vatican City’s telecom network, but they appear to be information-free AI clickbait articles.
There may have been some restriction or legislative reason regarding ipv6 until recently - China has gone from <5% to nearly 30% IPv6 capable since 2019: https://stats.labs.apnic.net/ipv6/CN
Governments should require IPv6 support for any online service or connected device they buy. If that’s not a requirement for (sub)contractors, then they won’t put effort into it.
This kind of requirements might also exclude a lot of crappy devices/services that have an outdated tech stack.
A common requirement in government contracts is “there must be no IPv6 support, and if there is it must be verifiably disabled to decrease the size of the vulnerability surface.”
Many years ago, that misconfigured firewall that let IPv6 traffic through without even bothering to log it, resulting in a years-long compromise scared a lot of govvies, but unfortunately it taught them the wrong lesson.

Just random answers, since you’re question kinda implies it won’t be full with obvious looking countries
