.st is the Internet country code top-level domain (ccTLD) for S o Tom and Pr ncipe. The code is marketed worldwide as an abbreviation for various entities.

Second-level domains

Registrations are taken directly at the second level, but some names have been reserved for use in specialized third-level registrations (though not all of these are actually in use at present):

• nic.st: Official ST domain registry
• gov.st: Government of S o Tom and Pr ncipe
• saotome.st: Island of S o Tom
• principe.st: Island of Principe
• consulado.st: S o Tom and Pr ncipe consulates
• embaixada.st: S o Tom and Pr ncipe embassies
• org.st, edu.st, net.st, com.st, store.st, mil.st, co.st

Other uses

The .st domain is being marketed as a general-use domain, with a number of meanings suggested including the abbreviation of "street", 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]".

Smalltalk

The Smalltalk programming language community also has an affiliation with the .st extension referring to the Smalltalk programming language. Both "The World of Smalltalk" (www.world.st) as well as the Seaside (www.seaside.st) web application framework use .st for their domain name.

Styria

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

Washington Post URL shortener

The Washington Post uses .st as part of their domain http://wapo.st. Their .st URL serves as a redirect which they use to lead readers to various articles on their site. This is most useful when the length of a URL counts, such as when tweeting an article. The Economist does the same, under econ.st.
