It will probably be linked to /dev/eth0.
The Dial up interface will be linked to /dev/ppp0, and will probably be
assigned its IP address from the ISP using DHCP.
ppp0 only matters when you are connected up, and will be set as the
route through which you access any ip address not directly on your lan.
