Pointcast and destination IP 1.1.1.1

[chouanard () PARC XEROX COM (Jean Chouanard)]

Sniffing the network I can see this strange behavior:
Each time a PC client is starting a pointcast update, it will send packets
with a destination IP address of 1.1.1.1
The destination port is 12345, 1 or 8080
The source port varies

I have look at the pointcast knowledge-db wo/ finding anything

Anyone have any idea on that?

Thanks,
