Free tiera free dynamic DNS service on the nsupdate.info suffix, several hosts per user, with no ads or spam
unit objects; metered on none
Pricenone stated
Bindingnone no count, expiry or review is published on the pages read, so no limit binds there; the zone is the operator's
Identityemail new account registration is closed on the public service; the sign-up page states that registration of new accounts is currently not possible, and the software's feature list names local or remote account login
Egressno query cap published
Per-object capunverified: the pages read say multiple hosts per user and publish no number
Retentionunverified: no expiry, inactivity or confirmation rule is stated on the pages read
Interfacerest dynamic updates by the dyndns2 protocol that many routers and clients speak, with a separate secret for each host; a browser-based updater and a manual web update also exist
Toolingany dyndns2 client or router, curl, or the web interface
Composes witha free name for a changing address; the zone is the operator's, so it cannot be a Cloudflare zone; the project is open-source software that can also be run by the user on a machine of their own, which ranks after every hosted offer
Reliabilityan operator-run public service whose count and expiry rules were not found; the suffix is on the Public Suffix List, so the TLS limit counts per name
NotesThis record is the hosted public service. The count and the withdrawal rule are unverified. The zone is the operator's. The TLS limit does not bind, because the suffix is listed.
Evidence notedocumented the home page and the documentation introduction were read and quoted; no count, expiry or sign-up form was read; the TLS statement is an inference from the Let's Encrypt registered-domain rule and the Public Suffix List entry
