How do I clear my arp cache in windows

Go to an elevated command prompt by clicking START > SEARCH > CMD
When it finds the command prompt, right click and "Run as Administrator"
Execute the following command:

netsh interface ip delete arpcache

The above command will flush the entire ARP cache on your system.
Now as soon as network connections are made, the ARP cache will begin to repopulate.

To check what IPs are in the arp cache execute the following:

arp -a
