All changes to your domains and hostnames are now logged: IP updates (with client IP), record additions and deletions, admin actions, and PowerDNS sync events. This helps us respond quickly to abuse reports and provides a full history of your DNS configuration.

If you had a hostname on the original dyndns.dk site, your account has been migrated to KyedNS. Sign in with the same email address you used on dyndns.dk — no new registration needed. Your hostnames and settings are already here.

See a full history of all changes to your domains and hostnames under "My Activity" in the user menu. Every IP update, record change, and admin action is logged with timestamps. You can also see recent activity directly on each domain and hostname page.

Free dyndns.dk hostnames that haven't received an IP update in 90 days will get a warning email. After 180 days of inactivity, the hostname is automatically disabled to keep the namespace clean. You can re-enable your hostname at any time by logging in and updating your IP.

All your domains and dynamic hostnames in one view. Switch between All, Domains, and Dynamic tabs. See DNS status, IP addresses, and last update times at a glance. Logged-in users are redirected here automatically.

KyedNS now checks your domain's DNS status automatically. Stale domains are re-checked every 6 hours in the background. You can also trigger a manual check from the dashboard.

After changing a DNS record, check if it has propagated across 8 global resolvers (Google, Cloudflare, Quad9, OpenDNS, and more). See a progress bar and per-resolver status. Available from any domain page.

Step-by-step instructions for configuring your router to auto-update your hostname. Supports ASUS, Fritz!Box, Synology NAS, pfSense, DD-WRT/OpenWrt, and generic ddclient/cron setups. Your credentials are pre-filled — just follow the steps.

Upload a BIND zone file to bulk-import DNS records. Supports A, AAAA, CNAME, MX, TXT, SRV, and CAA records. SOA and NS records are skipped (managed by KyedNS).
