Hello, all. When I execute arp -a -n, there are lots of arp caches like below.Surely, I set netmask and Broadcast without problem and routing table also no problem. System is CentOS release 4.7 i386. I know how to delete the arp cache, but I don't know why .. # ifconfigeth0 Link encap:Ethernet HWaddr 00:A0:D1:E7:91:CC inet addr:192.168.195.36 Bcast:192.168.195.63 Mask:255.255.255.192 # route -n 192.168.195.0 0.0.0.0 255.255.255.192 U 0 0 0 eth00.0.0.0 192.168.195.36 0.0.0.0 UG 0 0 0 eth0 # arp -a -n ?
