le_dns for Business

Predictable, resilient DNS without the enterprise tax

Why Uncensored DNS Matters for Business

Most “business DNS” services come with filtering - but filtering creates problems:

False positives block legitimate traffic: Customer sites, partner APIs, development tools
Unpredictable behavior: Sudden blocklist updates can break production
No control: You can’t override or customize the filtering
Compliance issues: Some industries require unfiltered access to specific domains

le_dns gives you full control. No surprise blocklists. No mysterious “security” filtering. Just predictable DNS resolution.

Multi-Provider Resilience

Don’t put all your DNS eggs in one basket:

Our infrastructure:

2 geographic locations (more soon): gra (France), lim (Netherland)
2 hosting providers (more soon): OVHcloud, Scaleway, Hetzner

Target availability:

99.5% per server (informational, no SLA)
99.9% aggregate when using 2 resolvers
99.95% aggregate when using 3 resolvers

Note: We don’t sell SLAs because we’re honest about what we can deliver. But our multi-provider architecture is designed for high availability.

Secondary DNS Hosting

Need reliable nameservers for your domains? We provide free secondary DNS hosting for everyone:

Multi-geographic NS: ns1.ledns.eu (51.83.90.178), ns2.ledns.eu (51.89.103.206)
TSIG-secured transfers: HMAC-SHA256 authentication for zone transfers
Automated zone updates: NOTIFY + AXFR/IXFR support
Web UI + REST API: Manage zones via browser or automate with scripts
Domain verification: TXT record verification before activation

Perfect for: Organizations managing multiple domains, DNS resilience strategies, Kubernetes external-dns, infrastructure automation

For businesses operating in Europe, GDPR compliance isn’t optional:

EU-only hosting: All data processed in France & Germany (no US transfers)
Data Processing Agreement (DPA): Available at /dpa.html (GDPR Article 28 compliant)
IP pseudonymization: /16 IPv4, /48 IPv6 truncation at edge
Minimal retention: 7-day operational logs, 31-day aggregated metrics
No third-party sharing: Your data never leaves our infrastructure

Bonus: We’re honest about calling it “pseudonymization” (not “anonymization”) per GDPR Article 4(5)

Integration Examples

Recursive Resolver Configuration

Configure multiple resolvers for automatic failover:

Linux /etc/resolv.conf:

nameserver 51.75.96.82 # ns-gra.ledns.eu
nameserver 51.89.95.33 # ns-lim.ledns.eu
nameserver 151.115.80.165 # ns-waw.ledns.eu

DNS-over-HTTPS (DoH) for Corporate Traffic

Encrypt DNS queries for remote workers or branch offices:

DoH endpoint: https://ledns.eu/dns-query
Use cases: Remote workers, mobile devices, encrypted DNS over untrusted networks

Secondary DNS Automation

Automate zone management via REST API:

Example: Add zone via API

curl -X POST https://ledns.eu/api/v1/zones \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"domain":"example.com","primary_ip":"192.0.2.1"}'

Pricing

Currently free for both resolver and secondary DNS.

We may introduce paid tiers in the future (with SLA guarantees), but:

30 days notice before any pricing changes
Existing free users will be grandfathered or offered migration paths
Free tier will likely remain available

Why Not Just Use [Big Cloud Provider]?

You could use AWS Route53, Cloudflare DNS, or Google Cloud DNS. But:

Vendor lock-in: Hard to migrate once you’re in their ecosystem
US-based data processing: GDPR complications with Schrems II
Filtering policies: Subject to change without notice
Cost unpredictability: Query charges can spiral on high-traffic domains

le_dns is EU-based, transparent, and simple. No lock-in. No surprise bills. No mystery filtering.
