How to Configure Alternate DNS Server
Description: By default, the NetXGATE DNS Resolver queries the
root DNS servers
directly and does not use DNS servers configured under Alternate DNS Servers . This behavior may be changed, however, using below DNS Forwarder option. By contacting the roots directly by default, it eliminates many issues typically encountered by users with incorrect local DNS configurations, and the DNS results are more trustworthy and verifiable with Domain Name System Security Extensions (DNSSEC).
Another purpose of the alternate DNS servers are specified for load balancing on busy networks, if the primary DNS server is busy, it can forward requests to the alternate DNS server.
