A dynamic DNS update service

Project description

About is a free dynamic dns service. is also the name of the software used to implement it. If you like, you can use it to host the service on your own server.

The software project lives at:


  • Frontend: Dynamic DNS updates via dyndns2 protocol (like supported by many DSL/cable routers and client software).
  • Backends:
    • Uses DYNAMIC DNS UPDATE protocol (RFC 2136) to update compatible nameservers like BIND, PowerDNS and others (the nameserver itself is NOT included).
    • Optionally uses dyndns2 protocol to update other services - we can send updates to configurable 3rd party services when we receive an update from the router / update client.
  • Prominently shows visitor’s IPs (v4 and v6) on main view, shows reverse DNS lookup results (on host overview view).
  • Multiple Hosts per user (using separate secrets for security)
  • Add own domains / nameservers (public or only for yourself)
  • Login with local or remote accounts (google, github, bitbucket, … accounts - everything supported by python-social-auth package)
  • Manual IP updates via web interface
  • Shows time since last update via api, whether it used SSL or not
  • Shows v4 and v6 IP addresses (from master nameserver records)
  • Shows client / server fault counters, available and abuse flags
  • Supports IP v4 and v6, SSL.
  • Easy and simple web interface, it tries to actively help to configure routers / update clients / nameservers.
  • Made with security and privacy in mind
  • No nagging, no spamming, no ads - trying not to annoy users
  • Free and Open Source Software, made with Python and Django
