DDNS Updater vs DNSSEC

DDNS Updater keeps your DNS records aligned with your real public address when your ISP gives you a dynamic IP. Point your domain at home servers, NAS, VPN, or remote desktop without memorizing changing numbers. What you can do • Automatic updates — Push your current IPv4 and/or IPv6 to the DNS records you choose. • 60+ DNS providers — Including Cloudflare, GoDaddy, Namecheap, DuckDNS, No‑IP, DigitalOcean, Route53, deSEC, OVH, Porkbun, and many more (full list in the app). • Dual stack — Configure IPv4 and IPv6 separately so both A and AAAA stay accurate. • Flexible IP sources — Detect public IP the way that fits your network (e.g. via URL or interface-style options where supported). • Multiple profiles — Manage several domains or hosts from one place; run updates when you need them. • Import & export — Back up and move configuration between devices or your own automation. • Notifications — Optional alerts when your address changes so you are not surprised by a stale record. • Looks the way you like — Light, dark, or system theme with Material Design 3. • Multilingual UI — Use the app in the language you prefer. Who it’s for Home users, small offices, and builders who self‑host behind dynamic IPs and want a straightforward mobile client instead of router-only or script-only setups. Privacy-minded Your provider credentials and configuration stay on your device; the app talks to your DNS provider and IP-detection endpoints only as needed to perform updates you configure. Note Background update behavior may depend on iOS battery and background policies; open the app or use supported scheduling as needed for your provider’s TTL and change frequency.

DNSSEC routes your device's DNS queries through a DNSSEC-validating resolver — in one tap, without a VPN. Modern DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT) encrypt your queries in transit. DNSSEC validation at the resolver ensures the answers haven't been tampered with. Together they make DNS the private, trustworthy channel it was always meant to be. BUILT-IN DNS4EU PRESETS DNS4EU is the European Commission-backed public resolver network. Four presets ship with the app: • Protective — blocks malware and phishing domains • Protective + Ad Blocking — adds tracker and ad filtering on top • Protective + Child Protection — adds adult content filtering • Unfiltered — encrypted and DNSSEC-validating, no content filtering Pick a preset and tap Apply. iOS will prompt you once to allow the DNS profile, then it's active system-wide. YOUR OWN RESOLVER Prefer a different provider? Add any DoH or DoT endpoint: • Enter a DoH URL (https://…) or a DoT hostname • Optionally add fallback IP addresses for bootstrapping • Flag it as DNSSEC-validating to track which resolvers you trust Custom resolvers are stored on-device and never leave it. ONE TAP, SYSTEM-WIDE The profile installs via the operating system's built-in DNS Settings — no VPN tunnel, no proxy, no configuration profile to trust manually. Once applied, every app on your device uses the configured resolver. Remove it any time from within the app or from Settings › General › VPN & Device Management › DNS. WORKS EVERYWHERE Available for iPhone, iPad, Mac, Apple TV, and Apple Vision Pro.
