Cloudflare DNS64 over HTTPS with any NAT64 prefix

	// A Cloudflare worker that uses https://dns.google to offer DNS64 over HTTP

	// which is not publicly routable over the internet.
	// See https://nat64.xyz/ for a list of publicly available NAT64 services and
	// their prefixes.
	//
	// To use this, deploy it to a worker, and then configure your DNS over HTTPS
	// resolver with this URL (specify more than one prefix for redundancy):
