LinkLayerAddress	4	Sonek, bağlantı yerel son ekidir.
Manual	1	Sonek el ile yapılandırıldı.

Açıklamalar

IP adresleri iki bölüme ayrılır: ön ek ve sonek. Adres ön eki bir IP adresinin ağ bölümünü, adres soneki ise ana bilgisayar bölümünü tanımlar. Ön ekler genel yetkililer tarafından atanır ve son ekler yerel sistem yöneticileri tarafından atanır.

Bu numaralandırma sınıfı tarafından UnicastIPAddressInformation kullanılır. Bir nesne için tek noktaya yayın adres bilgilerini NetworkInterface aldığınızda bu sınıfın örnekleri döndürülür.
