Proposed top-level domains

.geo was a generic top-level domain proposed by SRI International to be used to associate Internet resources with geographical locations, via a system of "georegistrars" and "georegistries" with hierarchical addresses representing locations in a grid encircling the Earth. These addresses are not intended to be typed in directly by end-users (and hence are "messy" strings like acme.2e5n.10e30n.geo) but rather, would be used "behind the scenes" by software looking things up by location (possibly driven by GPS positioning in mobile devices).

.mail was a potential generic top-level domain originally proposed by The Spamhaus Project in 2004, but rejected by ICANN. Its purpose was to enable responsible message recipients to reliably and efficiently identify and accept spam-free mailstreams. The ICANN Board issued a resolution on 4 February 2018 to cease the processing of all applications for the .corp, .home, and .mail gTLDs.

.bcn is a generic top-level domain for the city of Barcelona, Catalonia, Spain.

.web is a proposed top-level domain (TLD) that was created and assigned by an auction process to several bidding companies. It was awarded to Nu Dot Co LLC, which is primarily funded by Verisign.
