notation. IP addresses are comprised of two components: the network ID and the host ID. For example: In a class C network: 192.168.10.128 Network ID Host ID (16-bit block) (8-bit block) DNS (domain name system) is used with IP addresses. DNS converts domain names and websites to IP addresses‚ which a computer can read. The computer remembers the IP address so that the user doesn’t have to. DNS also aids in and controls the delivery of email. IP addresses are either classful

or routed with special gateways called routers which constitute the logical or physical boundaries between the subnets. The benefits of subnetting vary with each deployment scenario. In the address allocation architecture of the Internet using Classless Inter-Domain Routing (CIDR) and in large organizations‚ it is necessary to allocate address space efficiently. It may also enhance routing efficiency‚ or have advantages in network management when subnetworks are administratively controlled by different entities
