.gg
.gg is the country code top-level domain for the Bailiwick of Guernsey, including the islands of Guernsey, Alderney, Sark, Herm, Jethou and Lihou (plus several uninhabited islands and islets). It is administered by Island Networks.
A new trend is to use .gg for domain names relating to e-sports, where "gg" is a commonly used initialism for "good game".
The Search Engine DuckDuckGo uses the domain ddg.gg as a shortened version of duckduckgo.com.
