• The Forwarders on your DNS server

• The CNAME records on your DNS server for your host
• The Forward Lookup Zones on your DNS 

 

EXPLANATION

In Domain Name System (DNS) terms, a DNS forwarder is a DNS server that is used to forward DNS queries for external DNS names to DNS servers outside that network. It does it to DNS queries that it cannot resolve locally, meaning DNS queries
that it has no personal knowledge of. By using DNS forwarders you can improve the efficiency of name resolution for the computers in your network that query for DNS names outside your network (such as names on the Internet).
