Question
Explanation / Answer
Answer:
1) The default subnet mask for Class C is : 255.255.255.0.
-> Total bits for net work id 24/8
2) Super net:
Calculating supernet addresses:
Calculating a supernet address is easy if the approach is organized. determine how many hosts you want to have available on your network and reference that against the Hosts column to select the best match.
=> Then, once you select the appropriate number of hosts, you can look across the chart and see the corresponding supernet mask. With that, you will need to determine a valid starting network.
=> The Windows NT and 2000 do not allow the use of the X.X.X.255 or X.X.X.0 IP addresses. Because the available hosts for this range of addresses will exceed our requirements, the loss of these few addresses will not be an issue.
3)CIDR:
==>CIDR stands Classless Inter-Domain Routing.
==> CIDR, was developed as an alternative to traditional subnetting.
==> The idea is that you can add a specification in the IP address itself as to the number of significant bits that make up the routing or networking portion.
==> The IP addresses allow particular information packets to be sent to specific computers.
Example:
For example, we could express the idea that the IP address 192.16.20.0 is associated with the netmask 255.255.255.0 by using the CIDR notation of 192.16.20.0/24. This means that the first 24 bits of the IP address given are considered significant for the network routing.
