Public MustOverride ReadOnly Property DestinationUnreachableMessagesReceived As Long

Property Value

Type: System.Int64

An Int64 value that specifies the total number of Destination Unreachable messages received.

A Destination Unreachable message can be sent to the computer that is the source of a packet for any of the following reasons:

  • The computer cannot find a route to the destination address.

  • Communication with the destination address is administratively prohibited. For example, a firewall prevents delivery of packets to the destination.

  • The destination address is unreachable.

  • The destination port is unreachable. For example, there is no listener available for the packet's protocol.

The following example displays the value of this property.

Public Shared Sub ShowIcmpV6UnreachableData() 
    Dim properties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties()
    Dim statistics As IcmpV6Statistics = properties.GetIcmpV6Statistics()
    Console.WriteLine("  Destination Unreachables ............ Sent: {0,-10}   Received: {1,-10}", statistics.DestinationUnreachableMessagesSent, statistics.DestinationUnreachableMessagesReceived)

End Sub 'ShowIcmpV6UnreachableData
