|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 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).
I have two hacked domains: refuse.to.undo.it and 84.pon.tiac.dre.am.
Do you have any?
