/in-tər-ˌnet ə-ˈdres/
n. 1. [techspeak] An absolute network address of the form foo@bar.baz, where foo is a user name, bar is a sitename, and baz is a 'domain' name, possibly including periods itself. Contrast with bang path; see also network, the and network address. All Internet machines and most UUCP sites can now resolve these addresses, thanks to a large amount of behind-the-scenes magic and PD software written since 1980 or so.
See also bang path, domainist.
2. More loosely, any network address reachable through Internet; this includes bang path addresses and some internal corporate and government networks.
Reading Internet addresses is something of an art. Here are the four most important top-level functional Internet domains followed by a selection of geographical domains:
.com
commercial organizations
.edu
educational institutions
.gov
U.S. government civilian sites
.mil
U.S. military sites
Note that most of the sites in the com and edu domains are in the U.S. or Canada.
.us
sites in the U.S. outside the functional domains
.su
sites in the Soviet Union (see kremvax).
.uk
sites in the United Kingdom
Within the us domain, there are subdomains for the fifty states, each generally with a name identical to the state's postal abbreviation. Within the uk domain, there is an ac subdomain for academic sites and a co domain for commercial ones. Other top-level domains may be divided up in similar ways.
