What is the difference between DENIC eG and an Internet Service Provider?
DENIC eG in Frankfurt/Main administers the top level domain .de and operates the primary nameservers for the DE-domains. Therefore DENIC eG, which is borne by the German Internet Service Providers (ISPs), is the central registry for all DE-domains. DENIC eG offers no IP services (Internet access, webspace, etc.) to third parties and also does not manage websites. These services are provided by ISPs.
