The document discusses the structure and function of DNS as a distributed database system that manages name-to-address mapping for network communication. It explains different types of domains and organizational labels within the DNS hierarchy, as well as how address resolution occurs in client-server interactions. The document also highlights the role of IP addressing in network communications, specifically through the TCP/IP protocol suite's IPv4 structure.
IP Addresses and Its Uses
- 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.
