A 2015 analysis of Naenara, a browser associated with North Korea’s Red Star OS, led researcher Robert Hansen to suggest that the country’s internet traffic might pass through one—or a handful—of public IP addresses. That was an inference from the browser’s behavior, not proof that every North Korean user or network shared exactly one address. North Korea’s domestic Kwangmyong intranet is also distinct from access to the global internet.
What the Naenara browser analysis found
SecurityWeek reported in January 2015 on Hansen’s examination of Naenara 3.5, a Firefox-derived browser associated with Red Star OS. According to that account, the browser requested an internal address in the private 10.x.x.x range when it was first run. Hansen interpreted the address as a possible proxy or “mothership” through which traffic was funneled.

SecurityWeek also described browser settings involving Safe Browsing-style update and phishing-list mechanisms, North Korean-signed certificates, and email and calendar traffic. These were details attributed to Hansen’s analysis in the report, not independent confirmation of how the browser or national networks operated. SecurityWeek’s 2015 account is the basis for these observations.

Did North Korea use one public IP address?
Not as an established, countrywide fact. SecurityWeek characterized Hansen’s conclusion as traffic appearing to be routed through “one—or a handful—of public IP addresses.” The browser’s request to a private internal address was an observed behavior; the claim about the country’s public-facing traffic was a broader inference from it. Those are different kinds of evidence.
#1 Best Overall
A browser trace cannot establish that every person, institution, or network in a country uses the same public address. The available accounts do not provide a reliable current count of public IP addresses carrying all North Korean traffic. Hansen’s cautious inference should therefore not be turned into a definitive or present-day “one IP for the whole country” claim.

Kwangmyong is described as a domestic intranet, separate from the global internet. Analyst1’s 2022 assessment associates Kwangmyong with the private address range 10.0.0.0/8, while separately listing three ranges used for global internet connectivity. That distinction matters: internal addresses used on an intranet are not the same as public addresses through which external internet traffic may be routed. Analyst1’s 2022 assessment documents that separation.
Rank #2
An InterMedia report likewise describes Kwangmyong as a domestic intranet and discusses how Naenara’s internal endpoints, proxy settings, and certificate configuration could facilitate monitoring. This supports the distinction between domestic intranet use and external connectivity; it does not establish a current count of public IP addresses or show that all traffic follows one route. InterMedia’s report provides that context.

What the 2015 report can—and cannot—tell us
- It can tell us that the reported analysis concerned Naenara 3.5 and that the browser reportedly made a first-run request to a private internal address.
- It records Hansen’s interpretation that the setup might indicate traffic funneling through one or a small number of public IP addresses.
- It cannot establish that the entire country used exactly one public IP address, or that the same arrangement remains in place today.
- It should not be read as a complete network survey: the browser observations and the countrywide routing inference are not equivalent evidence.
