Комментарии

Этот класс предоставляет доступ к сведениям о конфигурации и адресе для сетевых интерфейсов, поддерживающих IPv4 или IPv6. Экземпляры этого класса не создаются; они возвращаются методом GetIPProperties .

Чтобы получить доступ к свойствам IPv4, используйте объект , возвращаемый методом GetIPv4Properties . Чтобы получить доступ к свойствам IPv6, используйте объект , возвращаемый методом GetIPv6Properties .
