Our verdict on nsupdate.info
nsupdate.info is a free dynamic DNS service for keeping hostnames mapped to changing IPv4 or IPv6 addresses. It is aimed at people managing home networks, LAN devices, routers, update clients, or self-hosted infrastructure. The service supports multiple hosts per user, custom domains and nameservers, browser-based updates, and related-host updates for LAN devices. Its open-source software can also be hosted on your own server, making it a natural fit for users who want control over the service or prefer self-hosted infrastructure.
Compatibility is a central strength. nsupdate.info supports dynamic DNS updates through the dyndns2 protocol and includes an RFC 2136 dynamic DNS backend. Documentation covers ddclient, inadyn, and python-dyndnsc, along with configuration for OpenWrt, DD-WRT, pfSense, and Fritz!Box devices. That combination gives users several ways to connect an existing router, client, or compatible nameserver instead of relying only on a browser. IPv4 and IPv6 support also makes it suitable for networks that need both address types.
The main practical constraint is availability for new users: new account registrations are currently unavailable. Custom domains with IPv4 nameservers are also currently broken, which narrows the usefulness of that feature for some configurations. Users who already have access and want free, flexible DDNS with open-source and self-hosting options should find a strong fit. Those needing immediate registration or dependable custom-domain support with IPv4 nameservers should choose another service instead.
