Impressive sleuthing!

It's interesting to discover the reality that packet routing ends up following political affiliations. I didn't know North Korea only has 1,024 IPv4 addresses. Do you know why so few IPs? How did they get them?

DPRK can certainly get however many IP addresses they want, DPRK just doesn't have that much infrastructure that they want externally accessible.

As far as I know, end-user traffic from within North Korea usually does not originate from those few IP addresses. Or at least not visibly so, they might be connecting to a proxy from a DPRK IP address.

"DPRK can certainly get however many IP addresses they want"

IP4 is quite limited as far as I know and not given out freely since a long time, or what do you mean here?

APNIC has some addresses [1] and will assign up to two /24s to qualified new accounts within the region. There are also carve outs for National Internet Registries and Internet eXchange Points.

[1] as of Nov 2025, approximately 3 million or a little more than 12,000 /24s https://www.apnic.net/manage-ip/ipv4-exhaustion/#how-to-tras...
