What's New

A new guided wizard helps you set up SPF and DMARC records for your domain. It auto-detects your email provider from existing MX records (Google Workspace, Microsoft 365, Fastmail, One.com, IONOS, Hetzner, and more), pre-selects the right SPF includes, and generates correct TXT records with explanations at each step.

Common questions about dynamic hostnames, account access, and custom domains are now answered at kyedns.com/faq. Covers router DDNS setup, the dyndns.dk migration, IPv6 dual-stack, magic link login, and more.

Each account now has a personal API token (visible on your profile). Use it to read your zones, custom domains, and DNS records via a simple JSON API — handy for scripting and integrations.

Revived the 2011 dyndns.dk WEBJUMP feature for free *.dyndns.dk hostnames. Set a URL like https://kyedns.com/go/yourhost.dyndns.dk as your browser homepage: every time the browser opens, your IP is updated and you're sent on to the destination you pick (e.g. google.com). No client to install, no router config, no scheduled tasks. Configure the redirect destination on the hostname page under Settings. The bookmark URL has no tokens — auth uses the 30-day sign-in session, so you'll re-authenticate roughly once a month. Useful if your router has no DDNS support and you just want something that works.

Dynamic hostname updates now propagate to public resolvers within one TTL instead of waiting up to an hour for the scheduled sync. When your IP changes, the zone serial is bumped immediately.

Subscribe to your personal activity feed in any RSS reader. Monitor IP changes, DNS syncs, and account events without logging in. Find the link on your My Activity page.

You can now configure up to two mail servers (MX records) for your dyndns.dk hostnames. Set them in hostname settings — they sync to DNS automatically.

You can now change your name and email address under Account Settings in the user menu. Email changes require verification — we send a confirmation link to your new address before switching.

If you registered a dyndns.dk hostname under a different email address, you can now transfer it to your current account by verifying your update password. No admin help needed — just go to DynDNS Hostnames and click "Claim Existing".
