Based in Starnberg, Germany, united-domains AG is the specialist for international domain registration. It targets companies as well as private users and offers over 500 global domain endings. The portfolio ranges from .au (for Australia) to .za (for South Africa).

For customers who cannot meet all registration requirements for certain domain endings (e.g. registered offices in the respective country), united-domains offers a proxy service and deals with all other formalities on site.

The company's core product is its unique Domain Portfolio, a web-based software tool for the administration of domain names. The Domain Portfolio can be used to administer and configure all domain names of a company or private person – irrespective of which provider registered the domains. In this way, Domain Portfolio becomes the customer's personal domain control center.
