remote Displays the remote IP address of the NTP peer.
ref clock Displays the IP address of the remote peer’s reference clock.

reach Displays the reachability to the peer (in octal bitstream).
delay Displays the time interval or delay for a packet to complete a round-trip to the NTP
time source (in milliseconds).
