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 Spain
Spain benefits from strong Iberian and Mediterranean internet infrastructure with major IXPs in Madrid (DE-CIX Madrid) and Barcelona. Madrid is a significant internet hub connecting Europe to North Africa and Latin America via multiple subsea cables. Most major public DNS resolvers have well-distributed points of presence across Spain.
Cloudflare DNS (1.1.1.1) averages 12 ms in Madrid and 14 ms in Barcelona. Google DNS (8.8.8.8) averages 14 ms in Madrid and 16 ms in Barcelona. Quad9 averages 13 ms in Madrid and 15 ms in Barcelona. In southern Spain near Seville and the Canary Islands, latency increases slightly to 16-24 ms.
Performance Rankings
Cloudflare 1.1.1.1 is the fastest option for most Spanish users, averaging 12-14 ms in Madrid. Google 8.8.8.8 is competitive at 14-16 ms. Quad9 performs well at 13-15 ms. NextDNS averages 15 ms. OpenDNS averages 18-24 ms. Spain's position as a gateway to Latin America provides excellent peering diversity.
ISP DNS in Spain
Spain's major ISPs include Movistar, Orange Spain, Vodafone Spain, and MasOrange (formerly MásMóvil). Movistar DNS averages 10-18 ms. Orange DNS averages 12-20 ms. Vodafone DNS averages 14-22 ms. MasOrange DNS averages 16-24 ms. Spanish ISP DNS is generally adequate, but switching to Cloudflare can improve resolution times by 15-25%, especially for international domains.

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.
