dyndns

Overview ¶

Package dyndns dynamically updates A/AAAA DNS records on Cloudflare.

Unlike other packages, this is intended to be used as a library (e.g. alongside an http.Server). It uses Cloudflare's 1.1.1.1 to get your public IP, and API Tokens for authentication.

See:

https://blog.cloudflare.com/api-tokens-general-availability/

Usage:

func main() {
	go dyndns.SyncDNS("example.com", "[Zone ID]", "[Edit zone DNS Token]", time.Minute)

	http.HandleFunc("/", func(w http.ResponseWriter, req *http.Request) {
		io.WriteString(w, "Hello, world!\n")
	})
	log.Fatal(http.ListenAndServe(":http", nil))
}
