예제

다음 코드는 IP 주소가 포함된 문자열을 IPv4의 점선 쿼드 표기법 또는 IPv6의 콜론 16진수 표기법으로 클래스의 IPAddress instance 변환합니다. 그런 다음 오버로드된 메서드를 ToString 사용하여 주소를 표준 표기법으로 표시합니다.

설명

정적 Parse 메서드는 IPv4에 대해 점선 쿼드 표기법으로 표현된 IP 주소와 IPv6에 대한 콜론 16진수 표기법으로 표현된 IP 주소에서 instance 만듭니다 IPAddress .

의 부분 수(각 부분은 마침표로 구분됨)는 ipString IP 주소가 생성되는 방식을 결정합니다. 한 부분 주소는 네트워크 주소에 직접 저장됩니다. 클래스 A 주소를 지정하는 데 편리한 두 부분 주소는 첫 번째 바이트에 선행 부분을 배치하고 후행 부분은 네트워크 주소의 오른쪽 3바이트에 배치합니다. 클래스 B 주소를 지정하는 데 편리한 3부 주소는 첫 번째 파트를 첫 번째 바이트에, 두 번째 부분은 두 번째 바이트에, 마지막 부분은 네트워크 주소의 오른쪽 2바이트에 배치합니다. 예를 들면 다음과 같습니다.
