Free tier	free hosted forward and reverse DNS with multiple domains per account, in open beta, for IPv6 certification or tunnelbroker account holders, colocation customers and transit customers unit objects; metered on none
Price	none stated
Per-object cap	no record count is published
Retention	zones persist while the account is active
Egress	no query cap published
Identity	email an account plus an IPv6 certification or a tunnelbroker account, or a colocation or transit relationship
Limits	write-gated the service is in open beta and is limited to IPv6 certification or tunnelbroker account holders, colocation customers and transit customers; no record count and no query cap is published source
Binding	write-gated
Interface	unknown a web panel; no documented REST API for record management. The dynamic-update path is a key-based URL that takes ipv4 and ipv6 separately and the dyndns key is the credential, which a script can call; the TXT variant exists for ACME DNS-01
Tooling	the web panel for zone and record management; the dyndns URL for dynamic A, AAAA and TXT records; no SDK and no documented REST API
Composes with	reverse DNS and secondary zones, which the other free providers in this set do not do as readily
Reliability	no reliability event recorded
Notes	An unpublished cap is a discretionary throttle. A design that depends on it has no ceiling to plan against, which is worse than a small published one. The interface field is 'unknown' rather than 'rest' because the only programmatic path is a key-based dyndns URL, which cannot create a zone or enumerate records.
Evidence rung	documented the service page was read today and states the eligibility gate and the dyndns syntax. No account was created, so the record and query caps stay unpublished.
Checked	2026-10-23 (live); stale on 2026-11-22

2026-10-22 Hurricane Electric's free DNS was recorded with `interface: rest` beside a detail field saying it has no REST API
