Domain Hack
A name that spans the dot to spell a word using the TLD, like del.icio.us or examp.le.
- glossary
A domain hack is a domain name whose registrable label and TLD together form a recognizable word, phrase, or abbreviation across the dot — classic examples include del.icio.us (delicious), instagr.am, and t.co. The technique typically exploits ccTLDs whose two-letter codes happen to double as word endings (.us, .am, .ly, .io), though some new generic TLDs also enable the trick. Domain hacks are prized as compact, memorable identifiers for startups and products, and short, cleverly constructed examples have sold for significant sums in the aftermarket. The creativity cuts both ways: a domain hack built around a brandable domain concept can be a strong asset, but one that incorporates a third party's trademark across the dot is just as vulnerable to dispute as any other infringing registration — UDRP panels look at the overall impression of the string, not at whether the dot is stylistically "part of the word."
