dnsupdate is a dynamic DNS client that has first-class support for IPv6 and aims to be easily configurable to meet the needs of any situation.
Unlike most other dynamic DNS clients, dnsupdate has been designed from the start to support IPv6 and many different update services. It is written in Python and configured using YAML, making it easy to use and extend.
This is free and open source software.
Key Features
- Built-in support for FreeDNS, nsupdate.info, as well as any service that uses the standard DynDNS protocol.
- IPv6 support.
- Simple YAML configuration file.
- Obtain addresses from a web service, router or local interface.
- Only submits an update if the address has changed.
- Respects API return values to avoid abuse bans.
