The nonprofit Internet Systems Consortium, Inc. (ISC) maintains sites that automatically return
lists of public time servers to an NTP client such as the server. Hence, the NTP Servers field is
initially filled in with the URL’s for these sites (0.pool.ntp.org, for example). Of course, this list
can be overwritten with the addresses of specific time servers you may want to use. However,
any attempt to clear the NTP Servers field will reset it to the default list.
Note: When URLs (non-numeric site addresses such as pool.ntp.org) are used in the NTP Servers
field, the IP address of at least one DNS (Domain Name server) must be provided in the
Name Servers
field. Typically, this address is supplied by the Internet Service Provider.
These name servers translate URL names into numeric IP addresses needed to access the sites
in question.
When using a GPS-based time server which is connected directly to a local area network, enter
its numeric IP address (such as 192.168.1.60) into the NTP Servers field, leaving the Name
Servers field blank.
Also, if the numeric IP addresses of the public or corporate time servers on the Internet is
known, these addresses can be entered, separated by spaces, in the NTP Servers field, leaving
the Name Servers field blank, since there would be no URLs to be resolved.
Note: Not all Network Time servers allow unlimited public access. Refer to www.ntp.org for
more information.
