Dynu vs DDNS Updater

The Dynu iOS App allows users to manage their dynamic DNS service as well as other services with an easy-to-use mobile application. The IP Update Client utility in the app detects any changes to your IP Address and reports it to Dynu DNS servers so that your domain name keeps mapped to the dynamic IP address. This application supports IPv4 and IPv6 updates as well as group and is an essential part of the dynamic DNS service.

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.
