Abstract
The present invention filters packets and reduces traffic when communication is performed with a device on a network utilizing the IPv6 protocol. To achieve this, a printer driver operating in a personal computer correlates and stores the name of the communicating party and an address for which communication actually succeeded from among addresses that have undergone name resolution, and uses the stored address in communicating with the same communicating party from then onward.
