Hello Richard,

The script categorises the hosts in the monitor list into:

Servers - The target is configured to obtain time from these hosts in
client/server mode. For example, an NTP daemon on the target has an
/etc/ntp.conf entry such as "server <IP_Address>".
Peers - The target is configured to obtain time from these hosts in
Symmetric Active mode. For example, an NTP daemon on the target has an
/etc/ntp.conf entry such as "peer <IP_Address>". Additionally, these
hosts may be NTP daemons which are configured with the target as a peer.
Clients - simply those hosts who contact the target to obtain time,
either in symmetric active mode or client/server mode.
Others - hosts who have sent NTP Control Mode or Private Mode
requests/commands to the target.

Private servers, peers and clients are hosts with private or special use
IP addresses e.g. from 192.168.0.0/16 etc.  If you're scanning a target
across the internet then any Private addresses will be of interest to
you since they may help to understand the topology of the remote private
network.
Public servers, peers and clients are hosts without private or special
use IP addresses.
Specifically, ipOps.isPrivate() is used to determine whether or not an
IP address is private or not.

Does that answer your question?
