Domain Hack

A name that spans the dot to spell a word using the TLD, like del.icio.us or examp.le.

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."

Author

Aileen Wright is a student in her twenties living in New York City, where the distance between a museum wall and a library reading room is a short walk and a long afternoon. She came to name writing through art and history — the way a single portrait, coin, or manuscript margin can carry a name across centuries and change its meaning on the way.

Most weeks you can find her in Central Park with a paperback, or in the quiet of a public reading room chasing down where a name actually comes from rather than what a name-list says it means. She is also teaching herself to code, which has made her oddly precise about spelling, sorting, and the small details that decide whether a name ages well.

For Namefi she writes about the history and culture behind domain names, the stories brands carry as they rename, and the difference between a good story and a verified source.

Victor Zhou is a technology founder and standards editor focused on digital identity and trust. He founded Namefi, edits Ethereum Improvement Proposals, and previously led smart-contract architecture work at Google Labs.

His work sits at the intersection of naming, ownership, and the systems people use to establish identity online. That perspective makes him especially interested in the way names move between personal meaning, public recognition, and digital infrastructure.

For Namefi, Victor edits and writes about domains as durable digital identity: how names become ownable onchain assets, how tokenization changes custody and trust, and what naming can learn from the systems people use to establish identity online.
