It definitely sounds like an IP address conflict. Another device on your network is using the *.*.*.98 IP address that the Dreamcast is trying to use. Could be the Pi or another device. The best thing to do would be to check on your router configuration page, look at the list of devices, and see what's using that IP. From there you can figure out what device needs to be assigned a different IP.
