ClouDNS

What Is ClouDNS?

Moving DNS off AWS Route 53 or Cloudflare feels riskier than it should. A misconfigured zone can take a domain offline for hours, and most teams delay the migration indefinitely rather than risk it. ClouDNS built its entire pitch around removing that friction: free zone migration, a genuinely usable free tier, and a support team that answers live chat in minutes rather than days.

Headquartered in Sofia, Bulgaria, ClouDNS runs a managed DNS service built on an anycast network of 65 points of presence across six continents. Cloud DNS Ltd was founded in 2010 and now manages domains for customers in more than 200 countries, handling upward of 8 billion queries a day. The company describes itself as the biggest European DNS hosting provider — a claim that's plausible given its scale, though it's ClouDNS's own framing rather than an independently audited market ranking.

What sets ClouDNS apart from the two default choices is jurisdiction. Route 53 sits inside Amazon, a US company. Cloudflare is also US-incorporated. ClouDNS is a Bulgarian entity (Company ID 202743734) operating under EU law and GDPR by default. For procurement teams weighing data-sovereignty questions, that's a structural difference, not a marketing footnote.

Key Features

How Fast Is ClouDNS's Anycast Network?

Speed is where ClouDNS makes its loudest claim, and the numbers back it up. As of May 2025, DNSPerf.com — an independent benchmarking service — ranked ClouDNS #1 for raw DNS performance among tracked providers. Average global response time sits under 14 milliseconds, dropping below 9 milliseconds across Europe and under 8 milliseconds in the United States.

That performance comes from real hardware at each of the 65 PoPs, not purely virtualised nodes layered on shared infrastructure. Twenty of those points of presence sit in Europe, with the rest spread across North America, Asia, South America, Africa, and Oceania. Every PoP runs dual-stack IPv4 and IPv6.

What's the Difference Between Premium DNS, DDoS Protected DNS, and GeoDNS?

ClouDNS splits its paid offering into three distinct product lines rather than one linear pricing ladder. Premium DNS, from $2.95 a month, adds anycast servers, DNS Failover, and DNSSEC on top of the free tier's feature set. DDoS Protected DNS, from $5.95 a month, swaps in hardened anycast servers built specifically to absorb volumetric attacks. GeoDNS, from $9.95 a month, adds geolocation-based query routing with EDNS-client-subnet support, so users get answers pointed at the nearest or most appropriate server for their region.

Each line scales independently. Premium DNS alone runs from a 5-zone entry tier up to a 400-zone, 500-million-query tier at $14.95 a month. Buyers pick the product line that matches their actual risk profile — a static marketing site doesn't need DDoS-hardened servers, but an e-commerce checkout domain probably does.

Does ClouDNS Support Dynamic DNS and Secondary DNS?

Yes, both are core to the platform rather than bolted-on afterthoughts. Dynamic DNS automatically updates A and AAAA records when a device's IP address changes, with update clients for wget, curl, PHP, Python, PowerShell, pfSense, and DD-WRT. It's aimed at home labs, CCTV setups, and IoT devices running behind residential connections without a static IP.

Secondary DNS lets customers run their own nameservers alongside ClouDNS's network, with zone transfers and instant NOTIFY updates keeping both in sync. Combined with an HTTP API for programmatic zone management, this covers most self-hosted and hybrid DNS architectures without requiring a full platform migration.

What Monitoring and Alerting Does ClouDNS Offer?

DNS Failover checks configured endpoints and reroutes traffic automatically when a server goes down. Notifications fire through email, SMS, Telegram, or webhook UP/DOWN events — the webhook option means failover status can feed straight into an existing incident-response pipeline rather than sitting in a separate dashboard. Higher tiers include more simultaneous health checks, scaling from one check on Premium S to unlimited checks on Enterprise.

Pricing

ClouDNS prices in US dollars with a structure closer to a menu than a ladder. The Free DNS plan costs nothing and includes 1 zone, 50 records, and 500,000 monthly queries served from 4 unicast servers. That's enough for a personal project or a small side business, but it skips DNSSEC, failover, and anycast routing.

Premium DNS starts at $2.95 a month for Premium S (5 zones, 200 records, 5 million queries) and rises to $4.95 for Premium M (50 zones, 2,000 records, DNSSEC, free SSL). The top tier, Premium L, costs $14.95 a month for 400 zones, 20,000 records, and 500 million queries. Annual billing shaves the cost of the M and L tiers further, though the entry-level S plan doesn't currently carry an annual discount.

DDoS Protected DNS starts separately at $5.95 a month, and GeoDNS at $9.95 a month — both scale similarly to Premium DNS but with their own feature floors. Both plans also carry a headline "up to 10,000% uptime SLA" — a service-credit multiplier ClouDNS pays out against downtime, not a literal percentage above 100% uptime. Enterprise DNS drops the published pricing entirely: unlimited zones, records, and queries, plus SAML SSO and white-label service, all quoted through ClouDNS's sales team.

Compared to Route 53's per-hosted-zone-plus-per-query billing, ClouDNS's flat monthly tiers are easier to forecast. Cloudflare's free DNS remains hard to beat on pure cost, but ClouDNS's paid tiers buy dedicated failover monitoring and GeoDNS routing that Cloudflare doesn't offer on equivalent terms.

EU Compliance & Privacy

ClouDNS is registered in Bulgaria as Cloud DNS Ltd, placing the company squarely under GDPR and EU data protection law. It also holds ISO/IEC 27001:2013 certification, covering its information security management processes. Neither Route 53 nor Cloudflare can offer that jurisdictional profile — both are US-incorporated, regardless of where they operate EU data centres.

It's worth being precise about what that jurisdiction does and doesn't guarantee. Anycast DNS, by design, answers queries from whichever point of presence is geographically closest to the requester. ClouDNS's 65 PoPs span six continents specifically so that a user in Tokyo or São Paulo gets a fast answer, not one routed through Sofia. That's true of every anycast DNS provider, European or not — it's how the technology works, not a ClouDNS-specific compromise.

The EU advantage sits at the company level rather than the packet level: the legal entity holding customer accounts, billing records, and support communications is Bulgarian and answerable to EU regulators. Public sector buyers, healthcare providers, and anyone scrutinising sub-processor location in a GDPR data processing agreement will find that distinction carries real weight, separate from where DNS queries themselves happen to resolve.

Who It's Best For

European businesses migrating away from US-owned DNS providers for jurisdictional or procurement reasons will find ClouDNS the most straightforward swap. Free zone migration removes the usual excuse for delaying the move, and the feature parity with Route 53 on core DNS functionality is close.

Cost-conscious teams running multiple domains benefit from ClouDNS's per-zone pricing model. A developer or small agency managing a dozen client domains can run Premium M for under $5 a month rather than paying per-query fees that scale unpredictably with traffic spikes.

Anyone needing Dynamic DNS for home or IoT infrastructure gets a genuinely free, forever-free option with broad client support — a niche Route 53 and Cloudflare don't compete in directly.

ClouDNS is a weaker fit for teams already deep inside the Cloudflare ecosystem wanting DNS bundled with CDN, WAF, and bot management. AWS-native shops leaning on Route 53's tight integration with ACM, ALB, and health checks won't find a direct replacement either — those integrations don't transfer, and ClouDNS doesn't try to replace them.

The Verdict

ClouDNS earns its DNSPerf #1 ranking honestly — the anycast network is fast, the uptime SLAs are aggressive, and the free tier isn't a crippled trial disguised as a giveaway. Add Bulgarian EU jurisdiction and ISO 27001 certification, and it's a legitimate answer for teams that specifically want DNS off US soil.

The trade-offs are real, though. Integration breadth trails Cloudflare and Route 53 by a wide margin, DNSSEC sits behind a paywall that some competitors give away free, and Enterprise pricing requires a sales conversation. Teams that just want fast, EU-jurisdiction DNS without a bundled CDN or security suite will find those trade-offs easy to accept. Anyone already leaning on Cloudflare's broader platform has less reason to switch.

Frequently Asked Questions

Is ClouDNS GDPR compliant and where is data hosted?

ClouDNS is a Bulgarian company (Cloud DNS Ltd, Company ID 202743734) headquartered in Sofia, so it operates under EU jurisdiction and GDPR by default, and holds ISO/IEC 27001:2013 certification. Like any anycast DNS service, query traffic is answered from the nearest of ClouDNS's 65 global points of presence for speed — that's how anycast DNS works, for every provider. The EU advantage is legal accountability: the company itself, and the accounts/billing data it holds, sit under Bulgarian and EU law rather than US jurisdiction.

How does ClouDNS compare to AWS Route 53 or Cloudflare DNS?

All three run global anycast networks with strong uptime. Route 53 integrates deepest with AWS infrastructure; Cloudflare bundles DNS with its CDN, WAF, and security suite for free. ClouDNS's edge is EU jurisdiction, a lower-cost entry point ($2.95/month vs. Route53's per-query billing), and a #1 DNSPerf raw-performance ranking as of May 2025. It trades away Cloudflare's bundled CDN/security stack and Route53's native AWS integration, staying a focused DNS specialist instead.

What's included in ClouDNS's free tier?

The Free DNS plan includes 1 DNS zone, 50 DNS records, and 500,000 monthly queries, served from 4 Unicast DNS servers, plus 1 mail forward and 1 Dynamic DNS hostname. It's free forever with no credit card required, though it doesn't include DNSSEC, DNS Failover, or the Anycast network — those require a paid Premium DNS plan or above.

How much does ClouDNS cost?

Paid plans start at $2.95/month for Premium S (5 zones, 200 records, 5M queries/month) and scale to Premium M at $4.95/month and Premium L at $14.95/month. Separate product lines exist for DDoS Protected DNS from $5.95/month and GeoDNS from $9.95/month. Enterprise DNS with unlimited zones and SAML SSO is quote-based through ClouDNS's sales team.

What does ClouDNS's #1 DNSPerf ranking actually mean?

DNSPerf.com independently benchmarks DNS providers on raw query response time from probes worldwide. As of May 2025, ClouDNS held the #1 spot for raw performance, with an average global response time under 14 milliseconds and under 9 milliseconds in Europe. That result reflects ClouDNS's 65-PoP anycast network, which uses dedicated hardware at each location rather than purely virtualised infrastructure.
