| Subnetting (A/L Model paper-2017) |
| XY Educational Institute has 3 computer labs and they want to network these labs with following number of computers. Each network is controlled separately. Lab 1- 100 Computers Lab 2- 60 Computers Lab 3- 50 Computers You are given 191.200.10.0/24 as the IP address & you have to setup following subnets using the IP address space. (i). How many usable IP addresses are available in the above IP address range? (ii). Write down the network address for each subnet. |

| Answer | (i) 28-2=254 (ii) 100 Computers means 7 bits needs for Host ID part. Then new mask is 255.255.255.128 Only 2 subnets possible 191.200.10.0 /25 191.200.10.128 /25 |

| Answer | You can divide one subnet like 191.200.10.128 /25 further into 2 Then mask is 255.255.255.192 Then subnet addresses : 191.200.10.128 /26 191.200.10.192 /26 But this type of variable length sub netting type questions are not asked in A/L |
