Improve your website's SEO, performance, and user experience with DNS Anycast
July 28, 2025 | Jordi Genescà Prat
For companies operating in multiple countries or serving users from different locations worldwide, a standard DNS infrastructure may not be enough. Traditional, centralized DNS servers with long resolution paths can lead to slow website loading times, loss of availability during critical moments, or exposure to distributed attacks.
In an environment where latency, service continuity, and resilience are crucial to digital reputation, having a robust solution is no longer optional — it's an operational necessity.
What is DNS Anycast?
DNS Anycast allows multiple DNS servers, distributed across different geographic locations, to share the same IP address. When a user makes a DNS query, it is automatically routed to the nearest server — or the one with the best performance at that time — reducing latency and improving availability immediately and consistently.
This model contrasts with the traditional Unicast network approach, where each server has a unique IP and all requests are routed to fixed locations, regardless of the user's origin or the global network state.
Key Benefits of DNS Anycast
Significant latency reduction
Thanks to smart routing to the closest node, DNS Anycast improves response times by 25% to 40% in international traffic environments, based on benchmark tests compared to standard DNS networks. This translates into smoother navigation, lower bounce rates, and a more consistent user experience.
High availability and fault tolerance
The distributed structure automatically redirects traffic in case of node failure or regional congestion. This ensures near 100% service continuity, even during technical incidents or targeted attacks on parts of the network.
Protection against DDoS attacks
By distributing requests across multiple servers and access points, DNS Anycast dilutes the impact of distributed denial-of-service (DDoS) attacks. This architecture reduces the attack surface and strengthens the global DNS system’s security against external threats.
Improved search engine performance and conversion rates
Faster DNS resolution leads to shorter loading times, which positively impacts key metrics like technical SEO, eCommerce conversion rates, and user retention on the website. In contexts where every second matters — such as international campaigns or global launches — these improvements can be critical.
Businesses that benefit the most
DNS Anycast is especially recommended for:
- Companies with an international presence: that need their web services to behave consistently across different continents.
- eCommerce businesses: where loading speed directly impacts conversion rates.
- Digital media and content platforms: that require low latency to deliver video, audio, or real-time news.
- Financial or legal service providers: for whom availability and security are critical.
- Technology startups: that operate in the cloud and scale quickly across markets.
