Açıklamalar

yöntemi, Resolve bir ana bilgisayar adı veya IP adresiyle ilişkili IP adresi için bir DNS sunucusunu sorgular.

Birden çok IP adresiyle ilişkilendirilmiş DNS stili bir ana bilgisayar adı olduğunda hostName , yalnızca bu ana bilgisayar adına çözümlenen ilk IP adresi döndürülür.

Ipv6Element.Enabled özelliği olarak ayarlanırsatrueAliases, döndürülen örneğin özelliği IPHostEntry bu yöntemle doldurulmazsa ve her zaman boş kalır.
