dynamic dns update client package that tries to be extensible, re-usable and efficient on network resources

Project description

Dyndnsc - dynamic dns update client

dyndnsc is both a script to be used directly as well as a re-usable and hopefully extensible python package for doing updates over http to dynamic dns services. This package currently focuses on supporting the dyndns2 protocol ( and variations thereof.


Basic example that should fit most peoples needs:

$ dyndnsc  --hostname --userid bob --password=fub4r

Are you using Miredo and want to assign a hostname dynamically to your ipv6 tunnel?

$ dyndnsc  --hostname --userid bob

Supported services

Currently, (at least basic) support is offered for

Feel free to send pull requests to add more.


$ pip install dyndnsc

or, if you want to work using the source tarball:

$ python install


  • Python 2.6, 2.7, 3.2 or 3.3


dyndnsc was born as a minimal module for use in the ANGEL APP, a p2p filesystem on top of webdav. At the time, the command line interface was not important. Now that time has passed, the goals are essentially to provide both an easy to use command line tool as well as providing an OK API for developers who want to add dyndns capabilities to their software. Also, providing support for many different ways of detecting and updating IP/DNS records is important.


dyndnsc is currently still in alpha stage, which means that any interface can still change at any time. For this to change, it shall be sufficient to have documented use of this package which will necessitate stability (i.e. community process).
