How to use the mdns/server.domain function in mdns

_announce(sock, onComplete, flush, repeat, unicast) {
		let message = require.weak("mdns/message");
		if (unicast)
			flush = false;		// RFC6762 10.2
		if (this.service)
			var msg = [
				{name: this.host, type: DNS_RRTYPE_A, addr: sock.addr, ttl: this.ttl, flush: flush},
				{name: this.name, type: DNS_RRTYPE_SRV, target: this.host, port: this.port, ttl: this.ttl, flush: flush},
				{name: this.service + "." + server.domain, type: DNS_RRTYPE_PTR, domain: this.name, ttl: this.ttl}, // !!! 'flush' MUST NOT ever be set !!!
			];
		else
			var msg = [
				{name: this.name, type: DNS_RRTYPE_A, addr: sock.addr, ttl: this.ttl, flush: flush},
				{name: sock.addr + ".in-addr.arpa", type: DNS_RRTYPE_PTR, domain: this.name, ttl: this.ttl, flush: flush},
			];
		if (this.txt)
			msg.push({name: this.name, type: DNS_RRTYPE_TXT, txt: this.txt, ttl: this.ttl, flush: flush});
		var an = message.announce(msg);
		return new MSocket(sock, {repeat: repeat, interval: [1000], data: an, unicast: unicast, onComplete: onComplete});
	};
