Portable information terminal, IP address setting program, and IP address setting method

摘要

The present invention has been made to provide a portable information terminal, an IP address setting program, and an IP address setting method capable of eliminating the need to assign a static IP address to each portable information terminal and eliminating the need to provide a DHCP server for each portable information terminal. A portable information terminal 1 performs a communication using an IP address by connecting to a USB-LAN adapter 2. The potable information terminal 1 has a USB interface 15 that connects to the USB-LAN adapter 2 and a controller 11 that reads an IP address previously stored in the USB-LAN adapter 2 through the USB interface 15 and sets the IP address to the portable information terminal as the IP address thereof.
