A simple Dynamic DNS source for octoDNS.

Supports both IPv4 and IPv6 addresses. Generally useful when you have a zone with staticly configured records but would also like to include a dynamic record, e.g. for your office or home on a non-fixed IP address.

By default it uses https://api.ident.me/ to find the public address of the machine running the sync.

pip install octodns-ddns

Pinning specific versions or SHAs is recommended to avoid unplanned upgrades.

# Start with the latest versions and don't just copy what's here
octodns==0.9.14
octodns-ddns==0.0.1

# Start with the latest/specific versions and don't just copy what's here

The following config will combine the records in ./config/example.com.yaml and the dynamically looked up address at dynamic.example.com. creating both IPv4 and IPv6 addresses.

providers:
  config:
    class: octodns.provider.yaml.YamlProvider
    directory: ./config
  dynamic:
    class: octodns_ddns.DdnsSource
  route53:
    class: octodns.provider.route53.Route53Provider
    access_key_id: env/AWS_ACCESS_KEY_ID
    secret_access_key: env/AWS_SECRET_ACCESS_KEY
zones:
  example.com.:
    sources:
      - config
      - dynamic  # will add dynamic.example.com.
    targets:
      - route53

You can configure it to only do A or AAAA by adding a types param to the provider config.

  dynamic:
    class: octodns_ddns.DdnsSource
    types:
      - A

If you would like to use an alternate provider for looking up your address you can configure urls with a and/or aaaa with urls that return the address as the content of the response.

  dynamic:
    class: octodns_ddns.DdnsSource
    urls:
      A: https://v4.ident.me/
      AAAA: https://v6.ident.me/
