Reviewed and updated by the DNS Speed Test research team. We benchmark DNS resolvers from multiple locations worldwide to provide accurate, data-driven recommendations.
DNS Landscape in Denmark
Denmark benefits from excellent Nordic internet infrastructure with strong connectivity to the NETNOD IXP in Stockholm and DE-CIX in Hamburg. Copenhagen is a major internet hub with multiple subsea cable landings. Most major public DNS resolvers have well-distributed points of presence across Denmark, ensuring consistently low latency nationwide.
Cloudflare DNS (1.1.1.1) averages 10 ms in Copenhagen and 14 ms in Aarhus. Google DNS (8.8.8.8) averages 12 ms in Copenhagen and 16 ms in Aarhus. Quad9 averages 11 ms in Copenhagen and 15 ms in Aarhus. Denmark's small geographic size and advanced fiber network ensure remarkably consistent DNS performance.
Performance Rankings
Cloudflare 1.1.1.1 is the fastest option for most Danish users, averaging 10-14 ms across major cities. Google 8.8.8.8 is competitive at 12-16 ms. Quad9 performs well at 11-15 ms. NextDNS averages 13 ms. OpenDNS averages 16-20 ms. Denmark's advanced infrastructure ensures all major providers deliver excellent performance.
ISP DNS in Denmark
Denmark's major ISPs include TDC, Telia, and 3 (Three). TDC DNS averages 8-14 ms. Telia DNS averages 10-16 ms. 3 DNS averages 12-18 ms. Danish ISP DNS is generally excellent, but switching to Cloudflare can still improve resolution times by 10-20%, especially for international domains.
Setup Guide
To change DNS, access your router settings or device network configuration. For Cloudflare, use 1.1.1.1 and 1.0.0.1. For Google, use 8.8.8.8 and 8.8.4.4. For Quad9, use 9.9.9.9 and 149.112.112.112.
