DNS Forwarding helps enhance performance, distributes the strain across your network’s resources, and makes your system more durable. It provides a mechanism to pass on namespaces or resource records that are not present in a local Domain Name System (DNS) server’s zone to a remote DNS server for the resolution of name queries both inside and outside of a network. These name queries can come from anywhere on the internet.
What consequences are there for failing to configure DNS forwarding?
If forwarding is not enabled, all DNS servers will make queries to external DNS resolvers if they do not already have the necessary addresses cached. This may cause an excessive amount of traffic on the network.
What exactly are DNS forwarders used for?
DNS forwarding is the process by which specific sets of DNS queries are sent to a designated server for resolution according to the DNS domain name that was included in the query rather than being handled by the initial server that was contacted by the client. This occurs rather than the initial server being able to resolve the query because it contains the DNS domain name. The functionality and resiliency of the network are both enhanced by this approach.
Which one, root hints or DNS forwarders, should I use?
On internal DNS servers, at lower levels of the namespace, is where you will find the finest usage for root hints. It is recommended that you do not use root hints for querying DNS servers that are located outside of your company. DNS forwarders are better able to carry out this role.
What are the most important advantages of using a DNS forwarder?
You can increase the effectiveness of name resolution for the computers in your network that make DNS name requests to servers that are located outside of your network by utilizing DNS forwarders.

What exactly are these root hints?
Your DNS servers can use root hints, which are a list of DNS servers on the Internet, to answer queries for names that they are unfamiliar with. Root hints are stored on your DNS servers. In the event that a DNS server is unable to resolve a name query utilizing its local data, it will make use of its root hints to transmit the query to another DNS server.
How can I tell whether the DNS forwarders are operating properly?

When running queries, use the NSLookup server option, and then follow it up with the forwarding DNS server IP.

What’s the difference between a DNS forwarder and a DNS resolver?
Excellent question! The DNS forwarder (or forwarders) communicate with the DNS service to let it know where to direct queries in the event that the DNS service does not “know” the answer (for example, if it is not authoritative or in the cache). In the event that the Infoblox appliance has to resolve a name or conduct a reverse lookup, the DNS resolver settings instruct it as to where to direct queries.

How many root servers are there currently?

Why do I need to use two different DNS servers?
The primary function of a secondary DNS server is to act as a backup in case the primary DNS server that manages your domain experiences an unexpected interruption in service. A secondary DNS server is constantly online and ready to process requests for service. As there is now more than one reliable source from which you may obtain the information you need, it will help to distribute the burden that is placed on the network.
