The Pacific island nation of Tuvalu found a unique way to profit from its country code (see .tv). Computers read Internet addresses from right to left. Thus, on encountering firstname.lastname@example.org, the message would first be sent to Sweden, since .se is the country code for Sweden. Swedish routers would then send the message to univ.oslo.net where it will be waiting for Sven the next time he signs on.

For example, to find websites in France about wine using the AltaVista search engine (www.altavista.com), one could type +wine +domain:fr. To do the same in Go (www.go.com), one would type +wine +site:fr.
