Subject: portscan on tcp ports 1024 to 1280

What application or exploit probes every tcp port between 1024 and 1280
(i.e. 256 different ports in random order). The source port is always
80 or 0. Every host on our network is being scanned in this manner from
several different places. Some source ip addresses are:

65.203.157.138
65.203.157.29
66.150.15.150
209.15.44.204

Thanks
Fletcher
