DNS Forwarder Configuration with Caching DNS | Linux DNS Server | Part5

DNS Forwarder Configuration with Caching DNS is demonstrated in this video. Any DNS server can act as a DNS Forwarder, however, here, we’ll focus on Caching DNS acting as a DNS Forwarder.

DNS Forwarder is a configuration, not a specific type of DNS Server. Any Server can act as a DNS Forwarder. When a DNS query is sent to a DNS Server, whether it be Primary, Secondary, or Caching DNS, the query is received and the query is resolved via the internet. DNS Forwarder works differently, instead of sending the query to the internet, it sends the DNS query to the Upstream DNS Server. First, It verifies whether the queried answer is in the DNS Cache, if it isn’t, it sends the query to the Upper-level DNS Server. Most ISP’s DNS servers act as a DNS proxy for their customers, they allow DNS queries from the customers DNS server. If we set up Caching DNS Server on the network, we should also configure it as a DNS Forwarder, so that it can respond to client queries faster. I’ve detailed, how to configure the forwarder DNS and how it works with the caching DNS in this video, so you’ll have a good understanding of DNS Query Forwarding and Cashing Behavior.
