+ Net::DNS is a collection of Perl modules to interface with
+ the Domain Name System (DNS) resolver. It allows the
+ programmer to perform queries that are beyond the
+ capabilities of gethostbyname and gethostbyaddr.
+
+ Resolver Objects
+
+ A resolver object is an instance of the Net::DNS::Resolver
+ class. A program can have multiple resolver objects, each
+ maintaining its own state information such as the
+ nameservers to be queried, whether recursion is desired,
+ etc.
+
+ Packet Objects
+
+ Net::DNS::Resolver queries return Net::DNS::Packet
+ objects. Packet objects have five sections:
+
+ o The header section, a Net::DNS::Header object.
+
+ o The question section, a list of Net::DNS::Question
+ objects.
+
+ o The answer section, a list of Net::DNS::RR objects.
+
+ o The authority section, a list of Net::DNS::RR objects.
+
+ o The additional section, a list of Net::DNS::RR objects.
+
+ Header Objects
+
+ Net::DNS::Header objects represent the header section of a
+ DNS packet.
+
+ Question Objects
+
+ Net::DNS::Question objects represent the query section of
+ a DNS packet.
+
+ RR Objects
+
+ Net::DNS::RR is the base class for DNS resource record
+ (RR) objects in the answer, authority, and additional
+ sections of a DNS packet.
