A method for generating privacy IP address includes pregenerating a first privacy address and generating a second privacy address when the first privacy address is allocated to an application. Addresses may be shared by applications or unique to a single application. A deprecation timer is started when an application binds to an allocated privacy address, now when the privacy address is generated. To minimize traffic flow disruptions a deprecated address is not deleted while the address remains in use. By pregenerating privacy addresses, an address can be promptly allocated to an application with out delays incurred by confirming that a new address is not a duplicate on the system. The method can be implicated on any device using privacy addresses, including mobile handset devices.

Method for efficiently generating privacy addresses

A method and apparatus for ensuring network address uniqueness is described herein. An address manager determines whether any link-local addresses associated with peripheral devices connected to a mobile device would conflict with a network assigned global address. The address manager negotiates with the network to avoid conflicts.

Method and apparatus for ensuring IPv6 uniqueness in a mobile subnetted environment

Methods and apparatus for resolving incompatible network configurations are described herein. A mobile device having peripheral devices connected thereto receives a request from a peripheral device, determines whether the address configuration protocol associated with the peripheral device is compatible with the network to which the mobile device is connected, and if not compatible, the mobile device translates the address configuration protocol of the peripheral device to one compatible with the network.
