Abstract: A method and a device for duplicating a data center having an original public address space (e.g. external IP address or domain name) and an original private address space (e.g. range of internal IP addresses) are described. The method comprises the steps of copying the data center for providing at least two copied data centers 11, 12; to each of the copied data centers 11, 12, allocating a new public address space (new IP address, new DNS namespace) and the original private address space of the data center; and providing an address translation component 40 which is configured to re address traffic such that traffic directed to an address of the original public address space is re-directed to a corresponding address of one of the new public address spaces of the copied data centers. The network address translation may be performed using cookie or URL re-direction or cookie or URL switching. The aim is to minimize effort required for configuring a network when performing data center duplication e.g. when splitting up an enterprise for regulatory or anti-trust reasons.
