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 you can
overwrite this list with the addresses of specific time servers you may want to use. However, if
you try to clear the NTP Servers field it will be reset 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 your 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 you know the numeric IP addresses of the public or corporate time servers on the
Internet, you can enter these addresses, 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.
