The inverse domain is used to map an adddress to a name.This
may happen,when a server has received a request from a
client to do a task.
Server has a file that contains a list of authorized
clients,the server list only the IP address of the
client(extracted from the received IP packet).
To determine if the client is onthe authorized list,the
server can send a query to the inverse DNS server and ask
for a mapping of address to name.This type of query is
called inverse or pointer query.
To handle a pointer query ,the inverse domain name is added
to the domain name space to the first level node called arpa.
