Updates in seconds, not minutes

Most DDNS providers cache for 30 minutes. DynIP propagates in under a minute end-to-end. Your router sends an update, your hostname resolves correctly worldwide within ~60 seconds.

60s TTL · NOTIFY-driven · Multi-region nameservers

Built on real DNS standards

RFC 2136 TSIG means your FortiGate, MikroTik, OPNsense, OpenWRT, or any router that speaks DNS UPDATE works out of the box. No proprietary clients. No vendor lock-in.

RFC 2136 TSIG · REST API · UDP/53 native

IPv6 done right

Modern ISPs increasingly give you native IPv6 alongside CGNATed IPv4. DynIP supports both: update A and AAAA records side-by-side, run IPv6-only zones, or both. Built for the network you have today and the network you'll have tomorrow.

AAAA records · Dual-stack · IPv6-only support · DNSSEC by default

RFC 2136 / TSIG updates available in {{ tsigSecondsRemaining }} seconds

We're propagating this zone to our nameservers. FortiGate and MikroTik (RFC 2136 / TSIG) need to wait — they're disabled below until propagation completes. HTTP API updates (cURL, PowerShell, Python, MikroTik HTTP, etc.) work right now.
