Domain hack

A domain hack is an unconventional domain name that combines domain labels (especially the top level domain) to spell out the full "name" or title of the domain, making a kind of geeky pun.

For example, the domains del.icio.us, blo.gs, and cr.yp.to make use of the top-level domains .us (United States), .gs (South Georgia and the South Sandwich Islands), and .to (Tonga) to spell "delicious", "blogs", and "crypto", respectively.

In this context, the "hack" represents a clever trick (as in programming), not an exploit or break-in (as in security).

Structure

Typical domain names follow the structure of example.com, where example is the 2nd-level domain (SLD) and com is the TLD (top level domain). A domain hack might take the form examp.le (using 2nd- and top-level domains examp and le), but that particular one is impossible, since there is no top-level domain le.

A domain hack can be composed of more than just a domain name, and also make use of the server's file structure. Various structures such as "examp.le", "exam.ple", "ex.am.ple", "ex.am/ple", are all possible structures used to create domain hacks.

The most popular and most sought after domain hacks are those that use only the SLD and TLD (top level domain) to construct the full title, as shown by the "examp.le" example structure, above. However, a domain hack may use third level domains, fourth level domains, etc., and even directories/folders after the domain name to construct the title. A non-working, extreme, example of this would be http://do.ma.in/ha/ck/. More domain hacks are possible than one might assume due to the approximately 300 gTLDs and ccTLDs that exist all around the world.

Some TLDs only permit registrations at the third or higher level, beneath names that represent some grouping of sites; however, in some cases, these names spell words themselves, such as co.in (coin), co.il (coil), and co.ck (cock).

Shorter domain names

Domain hacks offer the ability to produce extremely short domain names. A popular real world example is blo.gs with five letters total, versus the comparable blogs.com with eight letters. Other great example is xa.bi with just four letters owned by Xabi Vázquez.

History

On Monday, November 23 1992, inter.net was registered and is thought to be the first domain hack ever. goatse.cx was another early domain hack. On Friday, May 3 2002, icio.us was registered and eventually became del.icio.us, the most visited domain hack, with the prepending of the "del" third level domain.

One common domain hack in Spain is the domain pagina.de, translating roughly as "page.of", using the .de (Germany) TLD.

Yahoo! acquired blo.gs^[1] on June 14, 2005, and del.icio.us^[2] on December 9, 2005.

By the end of 2005, the registration of Spanish second level .es domains became widely unrestricted.

During the month of January 2006, Belgian domain names ending in .be were available for free for users in the USA, UK, and Europe; due to the common use of the word "be" in English, and the number of words ending in "be" (such as "tube"), this was a prime opportunity to easily register domain hacks.
