Some of you make use of our DynDNS infrastructure that automatically assigns hostnames to computers with a dynamic IP address. This feature enables you to connect to your computer using its sent hostname, followed by the dhcp.phys.ethz.ch domain (eg example.dhcp.phys.ethz.ch) instead of the ever-changing dynamic IP address.

Thursday morning

Jan 30 2020 between 9:00 and 11:00

we will be migrating our DynDNS service to the servers of central Informatikdienste. As a consequence the resolution of example.dhcp.phys.ethz.ch to its dynamic IP address may not always work during that time. The global phys.ethz.ch and ethz.ch domains are not affected. Therefore the bulk of our users will not even notice the migration.

Update: Informatikdienste have postponed the migration from 23rd to 30th January.

Historically the D-PHYS print server has been accessible under the host name printer.ethz.ch. As it turns out, this name violates ID's DNS rules and they have requested we change it. We therefore have modified all references pointing to printer.ethz.ch to now address printer.phys.ethz.ch. We have incorporated some technical solutions that redirect many connections automatically, and also our managed workstations have been migrated, but there might be individual configurations that need manual intervention. So if printing stops working after Wednesday evening, you might have to change the print server address -- see our printing documentation.
