North Korea, like many countries, has its own country code top-level domain name.
This means any web address that ends with ".kp" is linked to the notoriously isolated nation, much like addresses that end ".de" are linked to Germany and ".jp" are linked to Japan.
What's unusual, however, is how few websites actually use that address. Thanks to an apparent mistake, North Korea has revealed that only 28 websites use the ".kp" domain name.
That's a remarkably small number. To put it in perspective, more than 16 million addresses end with Germany's ".de" domain name.
Many of the websites with the ".kp" domain name are familiar to North Korea watchers. They include kcna.kp or rodong.rep.kp, which belong to the state news agency and the state newspaper, respectively, or the website of Air Koryo, the national airline.
