This means that some machine decided to send an ARP packet for that host---which you received---even though you didn't (had no reason to) ARP for that host. What you need to do is compile a kernel with BPF in it and then run: # tcpdump arp host 198.96.21.224 This will tell you who is ARPing and who is sending the replies. (You may want to add a `-e' flag to see whether the replies are incorrectly being broadcast.) -GAWollman -- Garrett A.
