Our verdict on Dynu Dynamic DNS
Dynu Dynamic DNS maps hostnames to changing IPv4 or IPv6 addresses for home servers, remote access, webcams, game servers, and other internet-connected devices. It suits users who need free dynamic DNS with multiple hostnames, custom-domain support, router or firewall updates, and clients across Windows, macOS, Linux, iOS, Android, and browser extensions. The service also supports customer-owned domains, wildcard records, web redirects, offline settings, and location-based updates.
The published plans show a permanent Free account with unlimited DNS queries and free dynamic DNS service. The current pricing table lists up to 200 hostnames, while paid options add operational features. Member costs $9.99 per year and includes priority support, API access, DNSSEC, backup and restore, and logging. Corporate costs $99.99 per year and adds dedicated support, an advanced API, DNSSEC, backup and restore, and sub-accounts. These tiers make the service more suitable when administration, auditability, or support requirements extend beyond basic address updates.
Platform and integration coverage is a central strength. Dynu provides a RESTful API with API-key and OAuth2 authentication, DNS record management for A, AAAA, CNAME, MX, SPF, SRV, and TXT records, and IP-update clients for desktop, mobile, and browser platforms. It also lists support for routers and firewalls, cURL, DDClient, GnuDIP, NSUpdate, and Wget. Choose Dynu for broad free DDNS coverage and flexible update options; consider another service if DNSSEC, logging, backup and restore, or enhanced support must be included without a paid plan.
