What is your definition of latency? One-way or computational latency? If the first: divide the values by 2, assuming that send and return path are roughly the same. – user3549596 Sep 21 '19 at 21:13

ping -U <remote-address> for IPv4 or ping6 -U <remote-address> for IPv6

changed the answer. The parameter for this is `-U` ("Print full user-to-user latency") – Andreas Rogge Sep 23 '19 at 12:04
