2. Historical Service Addresses

The NTP service was once more complex with seperate stratums and an enforced hierarchy. There are a large number of devices in the university using the older service addresses and so to this end the older DNS names and addresses are maintained for the time being to reduce workload on IT staff university-wide.

The following addtional addresses are currently supported but should not be entered in new configuration:

ntp4.ox.ac.uk      has address 163.1.2.168
ntp0.oucs.ox.ac.uk has address 129.67.1.4
ntp1.oucs.ox.ac.uk has address 163.1.2.4
ntp2.oucs.ox.ac.uk has address 163.1.2.5
ntp3.oucs.ox.ac.uk has address 129.67.1.5

A DNS round robin of ntp.oucs.ox.ac.uk exists for the historical stratum 3 service.
