IPConfig, arp -a

ipconfig returns, among other things, the IP address of my local computer, correct?  If I ping this address, it should cause an ARP request for the MAC address.  If I then issue arp -a, I should see an entry for my computers IP address.  I do not.  I'm trying to determine the MAC address of my NIC card.   Thanks

yes, it does.  Thanks.  But why doesn't the ping cause and entry in the ARP cache that I could view with arp -a?

because your computer already knows its mac address. It doesn't need an entry in the arp table for it
