About
dynv6 is a dynamic DNS service for IPv4 and IPv6 addresses. It provides public hostnames for changing addresses and supports assigning hostnames to private hosts without manual NAT or port forwarding setup.
The service exposes multiple update methods, including REST API, Update API, DynDNS API, SSH with public key authentication, DNS updates with TSIG keys, and webhooks for notifying external services when an IP address changes. The free offering is available by choosing a free hostname or delegating a domain to dynv6.

Free Tier Value
This free tier appears to be a genuinely uncapped perpetual offer: the page says it is free for everyone and does not show any paid plan, quota, or trial limit to anchor a monthly value against. Because there is no concrete usage cap or paid tier to compare with, the practical monthly value can’t be estimated defensibly, but the offer still has full feature parity for the free service itself.
What's included in the free tier
- Free dynamic DNS hostnames for IPv4 and IPv6
- No paid plans or usage quotas
