A internet protocol in data communications is the set o rules of specifications used to implement one or more layers of the OSI model.

2.  An inter-connected set of network from a
user point of view may appear simply as a
larger network.
 If each of the constituent network retain
identity in identity and special mechanism
are needed for communicating across
multiple networks, then the entire
configuration is often referred to as an

4.  DNS is distributed database system that work at
the transport layer to provide name-to-address
mapping for client application.
 DNS servers maintain databases that consist of
hierarchical name structures of the various
domains in order to use logical names for device
identification.
 This type of address/name resolution is called
service-provider initiated. The largest use of DNS

5.  Generic domains
 Country domains
 Inverse domains
 Generic domains define registered hosts
according to their generic behavior.

7.  Each node in the tree defines a domain, which is an index to the domain
section allows seven possible three-character labels.
 These describe the organization types as listed in below:
Label Description
 Com Commercial organization
 Edu Educational institutions
 Gov Government instituti0ns
 Int International organization
 Mil Military groups
 Net Network support centers

8. section follows the same
format as the generic domains but uses two
character country abbreviations (e.g., “us” for
United States) in place of the three-character
organizational abbreviations at the first level.
 Second-level labels can be organizational, or
they can be more specific, national
destinations.

10. is used to map an address to
a name.
 This may happen, for example, when a server has
received a request from a client to do a task.
 Whereas the server has a file that contains a list
of authorized clients, the server lists only the IP
address of the client.
 A protocol in data communications is the set o
rules of specifications used to implement one or
more layers of the OSI model.

11.  The network layer protocol in the TCP/IP
protocol suite is currently IPv4 having two
level address structure (net id and host id)
categorized into five classes (A, B, C, D
and E).
 It provided host-to-host communication
between systems in the Internet.
