IPAddressInformation.Address 속성

정의

네임스페이스:

System.Net.NetworkInformation

어셈블리:

System.Net.NetworkInformation.dll

IP(인터넷 프로토콜) 주소를 가져옵니다.

public:
 abstract property System::Net::IPAddress ^ Address { System::Net::IPAddress ^ get(); };

public abstract System.Net.IPAddress Address { get; }

member this.Address : System.Net.IPAddress

Public MustOverride ReadOnly Property Address As IPAddress

속성 값

IPAddress

인터페이스의 IP 주소가 포함된 IPAddress 인스턴스입니다.

예제

다음 코드 예제에서는 로컬 컴퓨터의 네트워크 인터페이스에 대한 멀티캐스트 주소를 표시합니다.

설명

IP 주소는 네트워크의 인터페이스를 고유하게 식별합니다.
