> # NTP Servers

> Field | Description
> --- | ---
> IP Address Type | The IP address type (IPv4 or IPv6) of the peer.
> Name or IP Address | The name or IP address of the peer.
> Mode | The association mode of the NTP server, with values coded as follows: Peer - A host operating in this mode sends periodic messages regardless of the reachability state or stratum of its peer. By operating in this mode the host, usually a LAN workstation, announces its willingness to be synchronized by, but not to synchronize the peer. Server - This type of association is ordinarily created upon arrival of a client request message and exists only in order to reply to that request, after which the association is dissolved. By operating in this mode the host, usually a LAN time server, announces its willingness to synchronize, but not to be synchronized by the peer.
> Preferred | Specifies whether this peer is the preferred one over the others. By default, NTP chooses the peer with which to synchronize the time on the local system. If true, NTP will choose the corresponding peer to synchronize the time with. If multiple entries are true, NTP will choose the first one to be set.
