Isn't this that Junos Evolved thing? Never played with it :-).

I can't remember a time when it wasn't the case, but I've only been running Junos since release 8.x. That said, since Junos 17.4R1, hardware-based platforms (including vMX and vSRX) have been on FreeBSD-11, which I believe defaults "ping" to IPv4 without the Juniper modifications. Mark.
