Get Started

what is secondary dns?

Secondary DNS provides redundancy for your domain's DNS. Your primary server (the one you control) pushes zone updates to our secondary servers via AXFR/IXFR transfers. If your primary goes down, our secondaries keep serving your DNS records.

Redundancy

Your domains stay online even if your primary DNS fails. We serve from multiple European locations.

Performance

Geographic distribution reduces latency. Queries are answered by the nearest server.

Compliance

Many registrars require at least 2 nameservers. We provide the second one.

qu'est-ce que le dns secondaire ?

Le DNS secondaire assure la redondance de votre domaine. Votre serveur primaire (celui que vous controlez) envoie les mises a jour de zone a nos serveurs secondaires via des transferts AXFR/IXFR. Si votre primaire tombe, nos secondaires continuent a servir vos enregistrements DNS.

Redondance

Vos domaines restent en ligne meme si votre DNS primaire echoue. Nous servons depuis plusieurs emplacements europeens.

Performance

La distribution geographique reduit la latence. Les requetes sont servies par le serveur le plus proche.

Conformite

Beaucoup de registrars exigent au moins 2 nameservers. Nous fournissons le second.

configuration examples

Add this to your BIND configuration after receiving your TSIG key:

// /etc/bind/named.conf.local // TSIG key from le dns (replace with your key) key "customer-xxxx.example.com" { algorithm hmac-sha256; secret "YOUR_TSIG_SECRET_HERE"; }; // Allow zone transfer to le dns servers server 51.75.96.82 { keys { "customer-xxxx.example.com"; }; }; server 51.89.95.33 { keys { "customer-xxxx.example.com"; }; }; // Your zone configuration zone "example.com" { type master; file "/etc/bind/zones/example.com.zone"; allow-transfer { key "customer-xxxx.example.com"; }; also-notify { 51.75.96.82; 51.89.95.33; }; };

For PowerDNS Authoritative Server:

# Add TSIG key pdnsutil import-tsig-key customer-xxxx.example.com hmac-sha256 'YOUR_TSIG_SECRET_HERE' # Set metadata for zone pdnsutil set-meta example.com TSIG-ALLOW-AXFR customer-xxxx.example.com pdnsutil set-meta example.com ALLOW-AXFR-FROM 51.75.96.82,51.89.95.33 pdnsutil set-meta example.com ALSO-NOTIFY 51.75.96.82,51.89.95.33

Use the REST API for automation:

# Register and get API key curl -X POST https://ledns.eu/api/v1/register \ -H "Content-Type: application/json" \ -d '{"email": "you@example.com"}' # Add a zone curl -X POST https://ledns.eu/api/v1/zones \ -H "Authorization: Bearer ldns_YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{"domain": "example.com", "primary_ip": "YOUR_PRIMARY_IP"}' # Verify domain ownership curl -X POST https://ledns.eu/api/v1/zones/example.com/verify \ -H "Authorization: Bearer ldns_YOUR_API_KEY"

our nameservers

After setup, add these NS records at your registrar:

ns-gra.ledns.eu 51.75.96.82 (Gravelines, FR) ns-lim.ledns.eu 51.89.95.33 (Limburg, DE)

Keep your primary nameserver as NS1, add ours as NS2/NS3.
