DNSforge is a German-based Domain Name System (DNS) resolver that helps users block advertisements, tracking tools, and malicious websites at the DNS level. Instead of relying on software installed on a device, DNSforge works by intercepting requests for website domains and filtering out harmful or unwanted content before the request reaches the user. It offers four different filtering profiles: normal, hard, clean, and blank. The normal profile blocks about 1.4 million domains associated with ads, trackers, and malware. The hard profile is more aggressive, blocking around 2.8 million domains, including some parts of Facebook. The clean profile adds extra filters for adult content, gambling sites, and enforces SafeSearch on search engines and YouTube, blocking approximately 8 million domains. The blank profile disables all filtering, allowing unrestricted access to all websites. DNSforge uses third-party lists of blocked domains, such as those maintained by hagezi or oisd, which are updated every night. Users can report any mistakenly blocked websites on the DNSforge forum. However, free users are limited to 100 DNS requests every 10 seconds. If this limit is exceeded, they face a 15-minute ban from the service. This restriction could be problematic for users with multiple devices connected to the same IP address, as the limit applies to the IP rather than individual devices. DNSforge claims it does not log any user queries, stating "keine Aufzeichnung von Zugriffen" (no recording of accesses). A transparency report requested in May 2026 revealed that German law enforcement agencies, including the police and the Federal Criminal Police Office (BKA), had made requests for data. However, DNSforge could not comply, as it does not retain any logs. The service also claims it does not censor any queries. For users concerned about potential privacy or legal gray areas, DNSforge suggests using DNS4EU, a European public DNS resolver that guarantees no logs and full compliance with European data protection laws. To use DNSforge, users can input "dnsforge.de" into Android’s private DNS settings or use its DoH (DNS over HTTPS) address in browsers like Firefox, Chrome, or Edge. On iOS devices, a configuration profile must be installed. Alternatively, users can use IPv6 or IPv4 addresses, though these methods transmit data in plain text, which is less secure. If users experience any issues, they can easily revert to their previous DNS settings.
