Clearing DNS Service Cache on Synology NAS

If you’re using the Synology DNS server for your local clients or services on the Synology NAS, then you might need to clear it’s cache.

It’s really simple, and after googling I couldn’t find a straight answer. So I did some digging and found this was the appropriate way to clear the DNS Service Cache on a DSM6.x

  1. Login via SSH as root
  2. Run “/var/packages/DNSServer/target/script/”
