Where are you running this ARP command? On a router, on a workstation? What does your network look like? >Internet Address Physical Address Type >211.16.12.1 00-05-5f-ee-e0-54 dynamic >211.16.13.14 00-05-5f-ee-e0-54 dynamic 00-05-5F is Cisco's vendor code. Perhaps it's your default gateway? What are the 211.16 addresses? Are they your local machines? I think we need more info to answer the question.... But perhaps knowing that the MAC address is a Cisco device will help. It could be the default gateway or the UBR at the service provider's network. But with no more info about your topology, I'm just guessing. Priscilla >for all other hosts as well the physical address is >same as above.
