Remarks

IPv4 is a network layer protocol that is responsible for routing data packets from its source computer to its destination.

For details on the IP traffic statistics available to applications, see the IPGlobalStatistics class documentation. Note that the object returned by this method reflects the statistics as of the time the IPGlobalStatistics object is created. This information is not updated dynamically.
