Other uses

The .st domain is being marketed as a general-use domain, with a number of meanings suggested including the abbreviation of "street", "state", short for "Star Trek" and more. The .st domain is also commonly used to create domain names that spell words ending in st, such as "[bur.st]". The Smalltalk programming language uses the .st extension, and several websites about it use the .st domain. The Washington Post uses .st as part of their URL shortening domain wapo.st, serving as a redirect to lead readers to various articles on their site, and other sites use similar URLs. PlayStation uses the shortlink play.st.


The state of Styria, in Austria, has ST as its unofficial but common abbreviation. Therefore, the .st extension is used by some small businesses located in Styria, despite Austria's own ccTLD .at being present.[1]

South Tyrol

Also some registrations in South Tyrol, an autonomous, chiefly German-speaking Italian province, use the .st extension to abbreviate the German name of Südtirol in opposition to Italy's .it.


There is limited usage of .st in Stockholm, Sweden, by smaller businesses and private people. Falck Emergency in Stockholm uses .st for all their employees in the ambulance service of the Swedish capital Stockholm. A new top level domain, .stockholm, has been registered and has become operational during 2018.[2]
