How to Clear Corrupt ARP Cache to fix website time out issues

ARP or Address Resolution Protocol Cache is like a table where, for certain websites, an ip address is stored. These IP address gets updated from time to time. Since you are not able to load, this ARP table may have gone corrupt for you. It means if the IP address has changed, you might not be able to open certain websites. You can read more about it here.

  • First, open the command prompt with Admin Privilege.
  • Type in arp -a, and you will see a list of IP entries available in it.
    • Each of these IP are matched to the hardware address, also called a MAC address.
    • Along with it, you can see the type which is either dynamic or static.
    • Static does no change and need to be updated manually or by clearing the cache.
  • Now to clear the cache, run this command: netsh interface ip delete arpcache
  • It will clean your table, and the network will rebuild the entries again, depending on how the system works.

Make sure to execute it with admin privileges by launching CMD as Admin. In case it gives you an error message, you will need to stop the Routing and Remote Services under Services.

  • Type services.msc in the Run Prompt and hit Enter.
  • Locate both the services. Right-click on each of them and choose to stop.
  • Once you clear the cache, then start the services.

It works perfectly on Windows 10/8/7 and Windows Server 2008 R2.
