Strange and long list of udp listeners

Does anyone else running 10.6.4 have a large list of listening udp ports? I ran a netstat today and after the normal ports I expected to be open (ssh and iTunes) I saw a long list of 5 digit udp ports listening. I have my Apple Firewall on and I've unchecked the Airport Utility "listen for Airport Devices with a yellow light" check box.

When I turn off the network interface, the ports go away. They re-appear when I turn on a network interface, any network interface. Here's the list of ports listening:
