NTP Addressing Modes

Setting up to receive NTP is

relatively easy to do once you

known what you want.

UNICAST (QUERY)

NTPS clocks and devices support the

Unicast Method of NTP (Network

Time Protocol) packets transfer. The

unicast method involves direct

transfer of requested information

from the NTP server to the NTP

client (clock or other device) based

on an automatically generated

electronic query or NTP time

request. The Unicast method is

supported simultaneously when

either the Broadcast or Multicast

modes are selected.

BROADCAST

UDP (User Datagram Protocol) Broadcasts

Some firewalls and routers will not forward

UDP broadcasts by default. Security

configurations may need to be adjusted to

allow the UDP broadcast packets to pass

on the configured port.
