Which function of DNS forwards lookup request to another DNS?
Forward lookup zones resolve names to IP addresses and Reverse lookup zones resolve IP addresses to names. Forwarders can be used on your DNS server to forward requests for which your DNS server does not have an authoritative answer.
What is DNS forwarding used for?
DNS forwarding allows you to forward requests from a local DNS server to a recursive DNS server outside the corporate network.
What is a DNS conditional forwarder?
Conditional forwarders are DNS servers that only forward queries for a specific domain name. A conditional forwarder is configured to forward queries to a specific forwarder based on the domain name in the query. It essentially adds a name-based condition to the forwarding process.
What is the difference between a record and Cname?
These are the main differences: The A record maps a name to one or more IP addresses when the IP are known and stable. The CNAME record maps a name to another name. It should only be used when there are no other records on that name.
How do I check DNS forwarding?
If everything is resolving correctly internally but not externally you can test the forwarding DNS server with the NSLookup command. This could be your ISP DNS server or the root hint servers. Use NSLookup server option followed by the forwarding DNS server IP to run queries.
Should I use DNS forwarders?
DNS Forwarding improves performance, load balances, and makes your network more resilient. It provides a way to pass on namespaces or resource records that are not contained in a local Domain Name System (DNS) server’s zone to remote DNS server for resolution of name queries both inside and outside a network.

What is the difference between DNS forwarding and HTTP redirection?
There’s occasionally some confusion between DNS forwarding and HTTP redirection or the use of CNAME records to designate DNS aliases. DNS forwarding exclusively refers to the process where specific DNS requests are forwarded to a designated DNS server for resolution.
Can I use DNS forwarding without a Windows Server?
Even if you do not have access to Windows Server or the ability to run a local DNS server, you can still experiment with DNS forwarding using a Google Public DNS or Cisco’s OpenDNS. Both are free options that allow you to experiment with DNS forwarding.
