.de ist die länderspezifische Top-Level-Domain (ccTLD) Deutschlands. Sie existiert seit November 1986 und zählt zu den ältesten Länder-TLDs weltweit. Verwaltet wird sie von der DENIC eG, der zentralen Betriebs- und Registrierungsstelle (Registry) für alle Domains unterhalb der Top-Level-Domain .de.

Am 5. November 1986 wurde .de gemäß ISO 3166 als länderbezogene Top-Level-Domain (ccTLD) für Deutschland in der IANA-Datenbank eingetragen.[1] Seit diesem Tag können .de-Domains registriert werden.[2] Im März 1988 verzeichnete das zu diesem Zeitpunkt an der Universität Dortmund angesiedelte Network Information Center für Deutschland sechs .de-Domains:,,,, und

Seit 1997 liegt die Verwaltung aller .de-Domains in Händen der ein Jahr zuvor gegründeten DENIC eG mit Sitz in Frankfurt am Main. Seit April 2012 sind mehr als 15 Millionen .de-Domains registriert.[3]

.de is the country code top-level domain (ccTLD) for the Federal Republic of Germany. DENIC (the Network Information Centre responsible for .de domains) does not require specific second-level domains, as it is the case with the .uk domain range which require domain for example.

The name is based on the first two letters of the German name for Germany (Deutschland). Prior to 1989, East Germany had a separate ISO 3166-1 code (dd), and had a never delegated ccTLD, .dd.

.de is currently the most popular ccTLD in terms of number of registrations with .uk being the second most popular ccTLD and .nl being third. It is second after .com among all TLDs.[1][2]

The first point of registration for .de domains was at the Department of Computer Science of the University of Dortmund. was among the first registered .de-domains.

.de registrations may be directly ordered from DENIC but it is faster and cheaper to do so via a DENIC member (registrar).

As of 23 October 2009, DENIC allowed the registration of single- and two-letter domains as well as number-only domains.[3]

Registrations of internationalized domain names are also accepted so that all diacritics of German and the eszett, ß, may be used.[4]

In many of the Romance languages, e.g., Spanish, French, Romanian and Portuguese, "de" expresses the genitive of a noun (like "of" in English). This is exploited in domain registrations under the German TLD for romance language webhosts that offer customized sites, like (theforum.of), cleverly encoding the site name into the URL path, such as, meaning theforum.of/wikipedia. "de" is also a common romanization of the Japanese word for "by", so there is potential for sites to exploit this ("" being travel by bus), but this has not been widely adopted.
