Open data on .ch domain names

The data offers an overview of historical development and also enables interested parties to conduct research and develop new insights and services related to the use of .ch domain names and the Swiss internet by combining this information with other data sources.

SWITCH publishes domain names and DNS data on this website, in compliance with all relevant data protection regulations. Based on experiences and feedback provided by users, SWITCH aims to offer more data on domain names publicly in future. We welcome feedback at opendata@switch.ch.

Selected Open Data

Since July 2018, we have been publishing a CSV file with the top 1,000 .ch domain names here each month. This file contains the domain names most frequently searched for on the DNS. The CSV files go back to July 2017, as we have access to data from this point onwards.

What does the list reveal?

These .ch domain names are the most important on the Swiss internet. They account for a significant proportion of internet traffic and are therefore highly dependent on a stable, secure Swiss internet.

How is it measured?

We measure the total number of DNS queries answered by a.nic.ch and b.nic.ch. These queries come not only from web services, but also from email and all other internet services.
