ARP question

DerekAustin26

I am studying Network+ basic commands and here's the problem..

I go to my command prompt and type:

ipconfig /all

I found my mac address and my ip address.

Now when I do "arp -a"
It shows MY IP address associated with a different mac address. Weird!

Then i type "get mac" to confirm my mac address and its the same as my "ipconfig /all" command.

Why is my "arp -a" showing my IP associated with a different Mac Address?

Are you certain you are looking at 'your' MAC address?

ARP and the ARP table
Arp

Arp
Displays and modifies entries in the Address Resolution Protocol (ARP) cache, which contains one or more tables that are used to store IP addresses and their resolved Ethernet or Token Ring physical addresses. There is a separate table for each Ethernet or Token Ring network adapter installed on your computer. Used without parameters, arp displays help.

Vs.

Ipconfig

Displays all current TCP/IP network configuration values and refreshes Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) settings. Used without parameters, ipconfig displays the IP address, subnet mask, and default gateway for all adapters.

You should see something on ipconfig /all

Vs.
Arp -a
