When running a DNS leak test through our proxy, you may see DNS resolvers in a country different from your selected exit node (for example, German DNS servers appearing when targeting the US). This is expected behavior caused by our security architecture — it is not a DNS leak. Our proxy servers perform a DNS lookup on incoming requests to verify that hostnames do not resolve to private or local IP addresses. This validation protects against DNS rebinding attacks, a class of vulnerability where an attacker tricks a proxy into connecting to internal network resources. Because this validation runs on our infrastructure, the DNS server used may be in a different region than your selected exit node, causing DNS leak test sites to detect it as a separate resolver. Your actual traffic still exits through a node in your selected country. The validation lookup is purely internal and is invisible to target websites — they only see the connection from the exit node’s IP address in the country you specified. The DNS resolver location has no impact on your browsing, scraping, or data collection.
