How define hostname edit 'config/conf.json', the syntaxe of this file respect json format { "hostname1" : { [property...] }, "hostname2" : { [property...] }, "hostname3" : { [property...] }, [...] "hostnameN" : { [property...] } } properties of a hostname "name" : { "ip" : "127.0.0.1", "description" : "je suis le serveur web local", "autority" : "dns.{name},admin@{name}", "mail" : { "ip" : "127.0.0.2", "name" : "mail.{name}", "priority" : 10 }, "nameserver" : [{ "ip" : "127.0.0.1", "name" : "ns1.{name}" }] } The hostname can have a short regex like syntaxe. * : this expression respect ".*" in regex; %w : this expression respect "[a-zA-Z0-9_]+" in regex; %h : this expression respect "[a-fA-F0-9]+" in regex; %d : this expression respect "[0-9]+" in regex;

sample conf.json :
	{
		"server.web" : {
			"ip" : "192.168.1.3",
			"nameserver" : [{
				"name" : "dns3.local.web"
			},{
				"ip" : "192.168.1.2",
				"name" : "dns2.local.web"
			},{
				"ip" : "192.168.1.1",
				"name" : "dns.local.web"
			}]
		},
		"!*.lo" : {
			"ip" : "127.0.0.1",
			"autority" : "dns.{name},admin@{name}",
	
			"nameserver" : [{
				"ip" : "127.0.0.1",
				"name" : "dns.{name}"
			},{
				"ip" : "127.0.0.1",
				"name" : "dns2.{name}"
			}]
	
		}
	}

Server confiurations(config/serv.ini) conf = configuration hostname file(if not defined is set to app://config/conf.json) host = your ip4 addresse to listen(if not defined listen all) port = port to listen(if not defined listen 53) Section nameserver = list of dns server used to found response when no response found on server(as a proxy, but it's eprouve the global performances) [nameserver] nameOfTheDnsServer1 = Ip_Address nameOfTheDnsServer2 = Ip_Address ... nameOfTheDnsServer3 = Ip_Address Section ttl = list of ttl in dns reponse (in secondes) [ttl] ip = ttl for any ip (A or AAAA) address (if not defined 77) ttl = ttl for any field different of ip (A or AAAA) (if not defined 600) refresh = time to refresh the zone (if not defined 1800) retry = time to retry when refresh (above) has expired (if not defined 900) expiration = ttl for DNS response (if not defined 604800)

	[ttl]
	    ttl = 600
