Free authoritative DNS, CDN, universal SSL and DDoS protection
Free provides authoritative DNS, basic CDN, universal SSL and DDoS protections for eligible zones; the free CDN is not website hosting. Zones created after September 2024 have lower record-count defaults (check the currently applicable DNS record cap); advanced performance/WAF features may require paid plans.
Free dynamic DNS subdomains under duckdns.org with IPv4/IPv6 updates using HTTPS.
Hostname quota, payment-card requirements and commercial-use terms not confirmed; verify account limits before relying on the service.
1 DNS zone, 50 DNS records, 500K monthly DNS queries, 4 unicast DNS servers, 1 mail forward and 1 Dynamic DNS hostname.
Only unicast nameservers are included. Anycast, DNSSEC, DNS failover and higher quotas are paid features. Commercial-use rights and card requirements for permanent Free DNS need confirmation.
Free authoritative DNS hosting with automatic DNSSEC and REST API; one dedyn.io hostname per account; bring-your-own domains subject to per-account quota; authenticated API limited to 2.000 requests/day.
No domain registration or commercial SLA. Domain creation is quota-controlled, and DNS record writes have per-domain rate limits (300/day); paid third-party domain registration may be needed. Commercial-use terms not independently confirmed.
Free authoritative DNS hosting with no published zone-count limit; A, AAAA, CAA, CNAME, MX, SRV, TXT, SSHFP and TLSA records, DNSSEC, Dynamic DNS and web redirects.
