1. A computing device comprising:at least one wireless interface adapted to wirelessly connect the computing device to an IP based network via a first wireless interface using a first interface identifier;
a user interface adapted to allow a user of the computing device to interact with destinations over the IP based network, through the first wireless interface, using a first public IP address associated with the computing device; and
wherein the computing device is adapted to operate as a second wireless interface and to:
wirelessly communicate with other wireless enabled computing devices to provide a given device of the other wireless enabled computing devices with access to the IP based network by serving the given device as the second wireless interface having a second interface identifier, distinct from the first interface identifier, and providing the given device access to the network via the first wireless interface; and
forward data traffic from the given device, through the computing device, through the first wireless interface, through the IP network, to a proxy server, such that the proxy server acts as a proxy of the given device and the given device operates on the network using a second public IP address distinct from the first public IP address, with the second public IP address associated with the given device.
