A mechanism is provided for attributing network addresses to virtual machines. A request for a number of addresses is received from a requesting entity, thereby forming a requested number of addresses. A length of continuous ranges of available addresses is compared to the requested number of addresses. A range of available addresses comprising a number of addresses greater than the requested number of addresses is selected from a memory, thereby forming a selected range of available addresses. A first new range comprising the requested number of addresses excised from the selected range of available addresses is defined and one or more farther new ranges are defined, comprising the remainder of the selected range of available addresses not belonging to the first new range. The first new range is attributed for the use of the requesting entity. |
