Remarks

This class provides access to configuration and address information for network interfaces that support IPv4 or IPv6. You do not create instances of this class; they are returned by the GetIPProperties method.

To access IPv4-specific properties, use the object returned by the GetIPv4Properties method. To access IPv6-specific properties, use the object returned by the GetIPv6Properties method.

Constructors

IPInterfaceProperties()

Initializes a new instance of the IPInterfaceProperties class.

Properties
