Use the shared provider abstraction for IPv4/IPv6 detection in legacy
mode.
Allow per-family provider overrides in config.json (ip4_provider /
ip6_provider)
and support disabling a family with "none". Update config parsing,
examples,
and the legacy update flow to use the provider-based detection client.
DNS updates
IP detection providers can sometimes return a Cloudflare anycast IP
instead
of the user's real public IP, causing incorrect DNS updates. When
REJECT_CLOUDFLARE_IPS=true, detected IPs are checked against
Cloudflare's
published IP ranges (ips-v4/ips-v6) and rejected if they match.
Add Cargo.toml, Cargo.lock and a full src/ tree with modules and tests
Update Dockerfile to build a Rust release binary and simplify CI/publish
Remove legacy Python script, requirements.txt, and startup helper
Switch .gitignore to Rust artifacts; update Dependabot and workflows to
cargo
Add .env example, docker-compose env, and update README and VSCode
settings
Remove the old Python implementation and requirements; add a Rust
implementation with Cargo.toml/Cargo.lock and full src/ modules, tests,
and notifier/heartbeat support. Update Dockerfile, build/publish
scripts, dependabot and workflows, README, and provide env-based
docker-compose and .env examples.
