Internet domain names

Among other things, domain names make it possible to assign a unique address to every website. These names, such as, are currently used very often, primarily for accessing websites or sending e-mails. Traditional extensions, such as .ch or .com, will be augmented by new top level domain names related to brands or geographic names. In this context, the Confederation has set a strategy which seeks to protect the country’s public interest in relation to the management of domain names. Furthermore, it has acquired the extension .swiss from ICANN (Internet Corporation for Assigned Names and Numbers). The registration of .swiss domain names is possible since autumn 2015.

In order to be able to receive information sent via the internet (e.g. a page displayed in the navigator), every computer must have a unique address consisting of series of numbers, the so-called IP address. They are substituted by names which are easier to memorise, so that users must not concern themselves with these numbers. These are known as domain names, which generally consist of sequences of letters separated by dots. The domain name system (DNS) is sub-divided into several levels. In the example  "ch" represents the top-level domain and "admin" the second-level domain. 

Every second-level domain is unique and can be registered only once under a top-level domain (TLD). 

In most cases, registration is on a "first come, first served" basis, i.e. the first person to apply for a domain name becomes its holder. 

At the global level, administration of the DNS and the introduction of new top-level domains (TLDs) is entrusted to the private organisation Internet Corporation for Assigned Names and Numbers (ICANN).

Second-level domain names can be assigned by appointed "registries", which are used by ICANN for the administration of top-level domains, or by the "registrars" accredited by ICANN. 

Accreditation agreement for registrars

ICANN currently accredits domain-name registrars

The applicant for a domain name is free to use the registrar of his choice. Many registrars are able to offer registrations in the same domain at different rates.


The technical management of the .ch domain in relation to the global internet domain name system has been delegated to SWITCH until the end of 2026. SWITCH also provides the service for accessing the registration data for .ch domain names (RDDS, formerly WHOIS). However, with the entry into force of the revision of the Ordinance on Internet Domains (ODI) on 1 January 2021, the personal information of holders of .ch domain names is no longer accessible via this service.


The new .swiss internet domain is available to the Swiss community since September 2015. For this purpose, the Confederation has signed a contract with ICANN (the Internet Corporation for Assigned Names and Numbers), the corporation which manages internet addresses. To promote competition and diversity in the domain name system, new extensions for domain names are gradually being made available. The 22 traditional generic extensions (e.g. .com, .org or .info) are joined by thematic (e.g. .hotel, .bank), geographical (e.g. .berlin, .florida) or brand-related extensions. This new feature is the result of a decision by ICANN.
