Virtual networks may be launched in a provider network with an initial IP address space (e.g., an IPv4 CIDR block). Methods are described that allow additional IP address spaces to be added to a virtual network. A new IP address space for a virtual network may be specified via an API. The specified space may be checked to insure that it does not overlap with IP spaces that are associated with the virtual network. If there are no overlaps, the space is added to the network, for example by adding the space to the network's route tables.

Resizing virtual private networks in provider network environments

Techniques for dynamic allocation of network address spaces in virtual networks implemented in a service provider system are described. Upon a scaling condition of an allocation rule being determined to be satisfied, a network address space of a virtual network can be automatically expanded or contracted. The scaling condition can be specified by a customer associated with the virtual network. The allocation rule may also include a allocation factor that indicates an amount of network addresses that are to be added to or removed from the virtual network.

Dynamic network address space allocation for virtual networks

Techniques for virtual network address space auto-migration are described. An existing network address space of a virtual network can be automatically migrated to a new network address space. The new network address space can be added to the virtual network, new subnets can be added to the new network address space that mirror existing subnets, and new compute instances can be added to the new subnets that mirror existing compute instances. Subsequent to the auto-migration, the virtual network can be connected with another network that has an address space that conflicted with the previous network address space of the virtual network but not the new network address space.
