Yerel a\u011fdaki bir cihaz\u0131n ba\u015fka bir a\u011fdaki cihazla ileti\u015fim kurmas\u0131 gerekti\u011finde, \u00f6ncelikle hedef IP adresinin ayn\u0131 yerel a\u011fda m\u0131 yoksa uzak a\u011fda m\u0131 oldu\u011funu kontrol eder. Hedef IP adresi yerel a\u011fda ise cihaz do\u011frudan hedef cihazla ileti\u015fim kurar.
