We have maintained our own recursive nameservers within EECS for many years, enabling client machines to resolve hostnames to IP addresses. These servers also functioned as local NTP (time) servers. In the spirit of simplification, we are retiring these machines and will be utilizing campus servers for these services.
Effective immediately, we are updating our DHCP configuration, to point clients instead to campus nameservers ns1.berkeley.edu (128.32.136.9 and 128.32.206.9) and ns2.berkeley.edu (128.32.136.12 and 128.32.206.12). We are similarly updating the setting for NTP servers, pointing to campus NTP servers ntp1.net.berkeley.edu and ntp2.net.berkeley.edu.
Most machines in EECS are DHCP clients, and will pick up these changes automatically.
If you have statically configured nameservers or NTP servers on your systems, please update your configuration as soon as possible.
