.dd

.dd was the assigned country code top-level domain (ccTLD) for the German Democratic Republic (East Germany). It was chosen based on the ISO 3166-1 alpha-2 code for the German Democratic Republic, the letters coming from the German name of the country, ''''. In accordance with IANA policy, .dd was therefore available to be assigned as the country code top-level domain (ccTLD) for East Germany. However, this was never done, and so .dd was never added to the root nameservers. Its only use was internally in an isolated network among the universities of Jena and Dresden.

AI overview

".dd" was a country code top-level domain that could have been assigned to East Germany based on its official ISO code, but it was never officially implemented on the internet's root nameservers. Instead, it was only used internally within an isolated computer network connecting universities in Jena and Dresden in East Germany.
