SWITCH is a Swiss foundation managing the .ch and .li country-code top-level domains for Switzerland and Liechtenstein, respectively. As the Swiss national research and education network organisation, SWITCH also manages the educational networks among Swiss universities and research facilities, and the links to other (non Swiss) university networks.

.ch is the country code top-level domain (ccTLD) for Switzerland in the Domain Name System of the Internet. Made available in 1987, only two years after .com, it is administered by SWITCH Information Technology Services.

.li is the Internet country code top-level domain (ccTLD) for Liechtenstein. The .li TLD was created in 1993. The domain is sponsored and administered by the University of Liechtenstein in Vaduz. Registration of .li domain names used to be managed by SWITCH, administrator of Switzerland's .ch ccTLD. In February 2013, SWITCH discontinued its .li registration service for private customers, delegating it to a number of recognized partner firms.

A top-level domain (TLD) is one of the domains at the highest level in the hierarchical Domain Name System of the Internet. The top-level domain names are installed in the root zone of the name space. For all domains in lower levels, it is the last part of the domain name, that is, the last label of a fully qualified domain name. For example, in the domain name www.example.com, the top-level domain is com. Responsibility for management of most top-level domains is delegated to specific organizations by the Internet Corporation for Assigned Names and Numbers (ICANN), which operates the Internet Assigned Numbers Authority (IANA), and is in charge of maintaining the DNS root zone.
