Question
Chapter 5, Problem 5E
Program Plan Intro
Subnet:
- Subnet divides the network into logical pieces. This process is known as subnetting.
- Systems or computers can communicate directly with each other if they belong to the same subnet or subnetwork.
- Subnet contains the host addresses of a particular network.
- The computers which are outside of a subnet can communicate with other computers only through routers.
Subnet mask:
- A subnet mask is a 32 bit number that is used to divide IP address into network and host addresses.
- The number of IPs to a specific network can be limited by a single subnet mask.
- Single network can be organized into smaller networks called subnets by using multiple subnet masks.
- Subnet mask is used to identify the computers that belong to a specific TCP/IP network.
- Systems or computers can communicate directly with each other if they are belongs to the same subnet.
- The computers which are outside of the subnet can communicate with other computers only through routers.
- Net mask is also defined as the amount of bits that are used for network portion.
Internet Protocol (IP) address:
- IP is a protocol used in network layer of internet model.
- It is used to routes the packet through an optimal path in a network.
- IP performs addressing to find the next computer in an optimal path.
- Each IP address consists of two parts; Network and Host part.
- An IP address is a 32 bit number containing 4 octets.
- Classless Inter-Domain Routing (CIDR) provides additional specification for an IP address where additional specification implies to the number of significant bits that makeup a network portion.
- Example: Consider an IP address “192.168.0.25”
- Given IP address is class C address so it is associated with a subnet mask “255.255.255.0”
- In CIDR notation, this can be represented as “192.168.0.25/24”. This means 24 bits of an IP address is significant for network portion.
