North Korean IP Address: What Can You Verify?

When you see a North Korean IP address in your server logs or analytics, the only thing you can truly verify is that the IP is allocated to an organization in the Democratic People’s Republic of Korea (DPRK). You cannot verify who specifically is using it, whether it is actually in North Korea, or whether the traffic is from a legitimate user, a proxy, or a misconfigured network. Here is what you can and cannot confirm, and how to interpret such IP addresses accurately.

How North Korean IP Addresses Are Allocated

The internet in North Korea is managed by the country’s state-run postal and telecommunications company, Korea Post and Telecommunications Corporation (KPTC). The country has a very small number of allocated IP addresses compared to most nations—roughly 1,000 to 5,000 public IPv4 addresses, though the exact number changes as allocations are made. The main ranges are under the AS number AS131279 (KPTC) and AS134764 (Star JV, a joint venture with a foreign partner). These ranges are registered in the global WHOIS database, which is the primary source for verifying that an IP belongs to North Korea.

Because the entire country has fewer IP addresses than a typical mid-sized company, the same IP is often used by many users or routed through a central gateway. This means that a single IP address may represent thousands of people or devices, making it impossible to pinpoint a specific user.

What You Can Verify About a North Korean IP

Using standard tools, you can verify the following:

• IP allocation: WHOIS lookup shows the registered owner (e.g., KPTC) and the country code (KP).
• Autonomous System (AS) number: The AS number indicates which network announces the IP on the global routing table.
• Geographic location (approximate): GeoIP databases may show the country as North Korea, but city-level data is often unreliable and may just show Pyongyang as a default.
• Reverse DNS (if set): Some North Korean IPs have hostnames that include “kp” or “star-co.kp”, but many do not have reverse DNS configured.

You cannot verify the physical location of the user, the device, or the purpose of the traffic. A North Korean IP could be a government server, a mobile device, or even a misconfigured router.

How to Look Up a North Korean IP

To verify an IP address, you can use public WHOIS services or command-line tools. Here is a simple process:

1. Open a WHOIS lookup website (e.g., ARIN, RIPE, or APNIC) or use the terminal command whois <IP>.
2. Check the “Country” field—it should be “KP” for North Korea.
3. Look at the “NetName” or “Organization” field—it often contains “KPTC” or “Star JV”.
4. Check the “Route” or “OriginAS” field to confirm the AS number.

For example, if you see an IP like 175.45.176.0/22, a WHOIS lookup will show it belongs to KPTC. However, this only tells you the network, not who is using it.

Why People See North Korean IPs in Their Logs

There are several reasons why a North Korean IP might appear in your website or server logs:

• Direct access: Someone in North Korea (likely a government or approved user) visited your site.
• Proxy or VPN: The traffic might be routed through a North Korean proxy, though this is rare because North Korea has limited international bandwidth.
• Scanning or attacks: North Korean IPs have been associated with cyberattacks, but many attacks attributed to North Korea actually use servers in other countries (e.g., China, Russia) to hide their origin.
• Misconfiguration: Sometimes a network administrator misconfigures a router, causing traffic to appear from a North Korean IP when it is actually from elsewhere.

It is important not to jump to conclusions. Seeing a North Korean IP does not automatically mean you are being attacked; it could be a benign visit or a bot.

Common Misconceptions About North Korean IPs

One common misconception is that all North Korean IPs are used for hacking. In reality, North Korea has a very small internet presence, and most of its IP addresses are used for government websites, email, and a few approved services. Another misconception is that you can “block” North Korean IPs to protect your site. While you can block the IP ranges, this will not stop sophisticated attackers who use other infrastructure. Additionally, blocking a whole country’s IP range is often unnecessary and may block legitimate traffic from researchers or journalists who use proxies to access North Korean content.

Another myth is that GeoIP databases are always accurate. For North Korea, the databases often only have a few entries, and the location is often set to Pyongyang by default. The actual user could be anywhere in the country, or even outside it if the IP is used by a foreign entity.

Limitations of IP Verification

IP addresses are not a reliable way to identify a person. They are shared, dynamic, and can be spoofed. Even if you verify that an IP belongs to North Korea, you cannot:

• Determine the exact physical location (city or building).
• Identify the individual user.
• Know if the IP is being used legitimately or as a proxy.
• Verify the intent of the traffic (e.g., attack vs. normal browsing).

For these reasons, security professionals use IP addresses only as one indicator among many, and they rely on behavioral analysis and threat intelligence to assess risk.

Practical Steps If You See a North Korean IP

If you notice a North Korean IP in your logs, here is what you can do:

1. Check the WHOIS record to confirm the allocation.
2. Look at the behavior—is it a single request or repeated scanning? Is it accessing sensitive files?
3. Compare with threat intelligence feeds that may flag known malicious IPs.
4. If suspicious, block the specific IP or the entire /24 range, but be aware that this may not stop a determined attacker.
5. Monitor for other indicators such as unusual login attempts or data exfiltration.

Remember that blocking an IP is a temporary measure. The best defense is to keep your software updated, use strong authentication, and monitor your logs for anomalies.

Frequently Asked Questions

Can I find the exact location of a North Korean IP?

No. GeoIP databases may show the country as North Korea, but they rarely provide a city or street address. The IP is often registered to a central network, so the location is effectively the whole country.

Is it illegal to visit North Korean websites?

In most countries, it is not illegal to visit a website, but some governments restrict access to North Korean content. Check your local laws. Additionally, visiting North Korean websites may expose you to malware, so use caution.

Are all North Korean IPs malicious?

No. Many North Korean IPs are used for legitimate government services, such as the Naenara news portal. However, some have been used in cyberattacks, so treat them with caution but not paranoia.

Why does my VPN show a North Korean IP?

Some VPN services offer servers in North Korea, though they are rare. If your VPN shows a North Korean IP, it is likely because you selected a server in that country, or the VPN is misconfigured. Check your VPN’s server list.

Can I trace an email back to a North Korean IP?

Email headers may show the originating IP, but this can be spoofed. If the IP is North Korean, it only indicates the sending server’s location, not necessarily the sender. Many attackers use compromised servers elsewhere.

Conclusion

In summary, you can verify that an IP address is allocated to North Korea, but you cannot verify the user, device, or intent behind it. Use IP information as a starting point for investigation, not as a definitive answer. Always combine IP data with other security tools and common sense.
