domainist /doh-mayn'ist/ adj. 1. Said of an {Internetaddress} (as opposed to a bang path) because the part to the right of the `@' specifies a nested series of `domains'; for example, esr@snark.thyrsus.com specifies the machine called snark in the subdomain called thyrsus within the top-level domain called com. See also big-endian, sense 2. 2. Said of a site, mailer, or routing program which knows how to handle domainist addresses. 3. Said of a person (esp. a site admin) who prefers domain addressing, supports a domainist mailer, or proselytizes for domainist addressing and disdains {bangpath} s. This term is now (1993) semi-obsolete, as most sites have converted.
