- Subnetting it mainly allows for create multiple networks in a logically manner so, that it may exist within a single Class G, H and S network.
- If you do not need to subnet, then you are able to use only a single network from your Class G, H and S network.
- Now to subnet a network, we have to extend the mask using some bits from host ID portion of the address and to create a subnetwork ID.
- Now by extending mask to be 266.266.266.232, we have to take 3-bits from original host address and to use them for making subnets.
- So, with this, these subnets have been created.

QUESTION 17 We assume that a LAN network includes 7 hosts (A, B, C, D, E. Fand G) which are connected by a switch. The contents of the switch's CAM table is as follows: (Port 1. Host A) - (Port 2. Host B) - (Port 3. Host - Port 4, Host D) - Port S. Hosta-Port 6, Host F) - (Port 7. HostG), Also, we assume that there is/are one or many host(s) that has/have sent fake...

Consider the topology shown below with following requirements Three subnets A, B, C, should have enough addresses, starting from 192.100.10.0 to support 500 interfaces, 200 interfaces, and 100 interfaces, respectively. Each of subnets, D, E, and F has 32 interfaces. (not required for address assignment.) The IP addresses for three subnets should be assigned continuously, with spacing of power-2, that means, 250 will be rounded to 256, and so on. For each subnet, the assignment should take the form a.b.c.d/x...
