Without forwarding, all DNS servers will query external DNS resolvers if they don’t have the required addresses cached. This can result in excessive network traffic.
What is forward known DNS server?

Is Consul a load balancer?
Consul is a free and open source tool that provides service discovery, health checking, load balancing, and a globally distributed key-value store. This is the job of the load balancing layer.
Does Kubernetes use Consul?

How is the DNS forwarding done in consul?
The DNS forwarding can be done using BIND, dnsmasq and iptables. By default, the Consul agent runs a DNS server listening on port 8600. By submitting DNS requests to the Consul agent’s DNS server, you can get the IP address of a node running the service in which you are interested.
Where does consul DNS listen on Port 8600?
By default, the Consul agent runs a DNS server listening on port 8600. By submitting DNS requests to the Consul agent’s DNS server, you can get the IP address of a node running the service in which you are interested. The Consul DNS interface makes the port information for a service available via the SRV records.
How to use consul bootstrapping in DNS server?
You can always use bootstrapping manually by using the following commands. In this case, we will assume that a 3-node consul cluster is to be built. DNS is served from port 53. The DNS forwarding can be done using BIND, dnsmasq and iptables. By default, the Consul agent runs a DNS server listening on port 8600.
What’s the IP address of the consul server?
