Some other device on the subnet is doing proxy arp.
No. there is no other card.
Not another card, another network device - the one with 00:23:5E:12:63:FE as it's ethernet MAC address.
and as you see, arp caches from eth0..
? (72.18.205.157) at 00:23:5E:12:63:FE [ether] on eth0
Your eth0 MAC address is: 00:A0:D1:E7:91:CC from the ifconfig output you posted. Look though the rest of the arp list to find the IP address in the 192.168.195.xx range with the 00:23:5E:12:63:FE MAC to see which device is sending the arps.
