Method for efficiently generating privacy addresses

A mobile handset, comprising:

• a processor;
• at least one network interface coupled to the processor;
• and
• a memory coupled to processor, the memory having stored therein processor executable software instructions configured to cause the processor to perform steps comprising:
• pre-generating a first privacy address;
• performing a duplicate address determination on the first privacy address;
• storing the first privacy address in the memory;
• receiving a request for an address from an application;
• recalling the first privacy address from the memory;
• allocating the first privacy address to the application;
• generating a second privacy address promptly in response to allocation of the first privacy address and prior to receipt of a request for an address by another application;
• performing a duplicate address determination on the second privacy address;
• and
• storing the second privacy address in the memory, wherein each privacy address is an Internet Protocol version 6 (IPv6) privacy address produced by generating a random Interface ID (private IID) and associating the private IID with a network prefix of a current access router.

A non-transitory processor readable storage medium having stored thereon processor executable instructions configured to cause a processor of a mobile handset to perform steps comprising:

• pre-generating a first privacy address;
• performing a duplicate address determination on the first privacy address;
• storing the first privacy address in memory of the mobile handset;
• receiving a request for an address from an application;
• recalling the first privacy address from the memory of the mobile handset;
• allocating the first privacy address to an application;
• generating a second privacy address promptly in response to allocation of the first privacy address and prior to receipt of a request for an address by another application;
• performing a duplicate address determination on the second privacy address;
• and
• storing the second privacy address in the memory of the mobile handset, wherein each privacy address is an Internet Protocol version 6 (IPv6) privacy address produced by generating a random Interface ID (private IID) and associating the private IID with a network prefix of a current access router.
