The North Korea is one of the countries that most of all is investing to improve its cyber capabilities and that has one of the largest cyber armies.

But North Korea is also known for its limited exposure on the Internet, it fears cyber attacks from foreign Governments against its infrastructure.

Until today no one had any idea of the number of websites registered by the country for its top-level domain, .kp.

This week something is changed, likely due to an error in the configuration of a North Korean nameserver. The apparent mistake has revealed a list of all the domains for the top-level domain .kp and related info.

According to leaked zone files, the North Korea has only 28 registered domains

“Now we have a complete list of domain names for the country and it’s surprisingly (or perhaps unsurprisingly) very small,” Matt Bryant, the expert who has found the mistake, said to Motherboard

After Bryant discovered the mistake, he downloaded the data from the domain name servers.

Some of the sites in the list are not reachable, experts speculated that they were flooded with the traffic of curious netizens and went down.
