TechTerm: Domain Hacks

A domain hack is an unconventional domain name that combines domain labels, especially the top-level domain (TLD), to spell out the full "name" or title of the domain, making a kind of pun. For example the second-level domain (SLD) blo.gs makes use of the TLD .gs (South Georgia and the South Sandwich Islands) to spell "blogs". The third-level domains del.icio.us and cr.yp.to make use of the SLDs icio.us and yp.to from the TLDs .us (United States) and .to (Tonga) to spell "delicious" and "crypto" respectively. A domain hack may use third-level domains, fourth-level domains, etc., and even directories/folders after the domain name to construct the title. For example the musical group Brave Combo's website is http://brave.com/bo/. More domain hacks are possible than one might assume due to the approximately 250 gTLDs and ccTLDs that exist all around the world. inter.net was registered and is thought to be the first domain hack ever. A domain hack is considered to be "perfect" when the periods are used as perfectly placed word separators. The most notable example, at the time of this writing, is stop.spamming.us. A domain hack is considered to be "minor" when the following two occur: 1) the TLD is not used in the title of the domain name, and 2) more than the SLD is used in the title of the domain name. An example of this could be http://dr.phil.com/ (Dr. Phil).
