Key-Systems, distributor and manager of domain names, was founded in 1998 by Alexander Siffrin and received it's accreditation from ICANN in October 2000 shortly after the US Government terminated the monopoly assigning Internet addresses. Key-Systems has several millions of domains on its platform and holds a second place among the leading registrars for global Top Level Domains (gTLDs) in Europe.[1] Key-Systems was ranked 411 in the "2009 Deloitte Technology Fast 500 EMEA Ranking and CEO Survey".[2] In 2009 Key-Systems opened new branches in The US[3] and Mexico.[4] Is an official member of DENIC[5] the registry of the country code Top-Level-Domain .DE for Germany (Deutschland).

DomainDiscount24 (dd24) ( is a fully automated domain registration portal, including web- and mailspace offers. It is available in five different languages, targeting at retail customers.

RRPproxy is especially attractive for domain-resellers of both gTLD and ccTLD domain names. ICANN accredited registrars and other Internet Service Provider can register domains through a comprehensive WebInterface, Direct-Socket-Access, Email-Template or by installing our cutting edge API (one API for all Domains).

BrandShelter helps to manage and monitor huge domain portfolios. A special dotBrand unit supports in planning, executing and operating the TLD. Through partnerships with industry leaders, the BrandShelter division (with an office in the United States as well) offers support in understanding TLD opportunities, determining which name(s) to pursue, and submitting and tracking applications with ICANN.
