Description 

BytesReceived 

Specifies the number of bytes in a response to an echo request. BytesReceived can be 0 to indicate an error condition, or when a time-out occurs prior to receiving a response to an echo request. 

FromIpAddress 

IP address received in a Ping response that identifies the host responding to the ping request. FromIPAddress can have the value '0.0.0.0' to indicate an error condition, or when a time-out occurs prior to receiving a response to an echo request. 

MsgType 

Byte value that identifies the message type received in response to an echo request. MsgType can have the value 0 when a time-out occurs prior to receiving a response to an echo request. 0 - net unreachable 1 - host unreachable 2 - protocol unreachable 3 - port unreachable 4 - fragmentation needed 5 - source route failed 

SequenceId 

Sequence identifier of the response to an echo request. SequenceId can be assigned the internal sequence number of TIdIcmpClient when a time-out occurs prior to receiving a response to an echo request. 

MsRoundTripTime 

MsRoundTripTime is a LongWord value in TReplyStatus that indicates the total number of milliseconds required to return the response to the echo request. MsRoundTripTime is calculated using the originate timestamp in the echo request and the number of milliseconds since midnight on the local computer. 

TimeToLive 

Byte value that indicates the Time to Live, in seconds, returned in the response to an echo request. TimeToLive is decremented at each machine in which the datagram is processed. TimeToLive is updated when TIdIcmpClient decodes the TIdIcmpClient.ReplyData response to an echo request. 

ReplyStatusType 

ReplyStatusType is a TReplyStatusType member variable that contains the type of replay decoded in the response to a TIdICMPClient echo request.
