Udhcpc is part of busybox. You disable it by using the nodhcp boot option.
My questions was about having more than one dhcp server on your network.
You got your IP address, router and nameserver form 192.168.0.1.
Were you expecting to get them from a different server?
Having more than one dhcp server on your network may result in random lockups due to IP collisions and incorrect router and dns assignments.
