Summary
In this chapter, you looked at components of DNS. You have seen the various types of records and zones. You also have looked at the process of finding a resource on the network.
A variety of DNS record types exist, which all work together to provide name mapping. A and PTR records are the most common records and are used to resolve addresses and names. Other record types identify DNS servers or other services on the network.
Globally, DNS uses an interrelated hierarchy of servers to resolve queries for resources outside the local network. This hierarchy begins with the root name servers and ends with your local DNS.
