3. A NIC of a computer has benn assigned an IP address of 172.31.192.166 with a mask
of 255.255.255.248. to which subnet does IP adrress belong?

subnetworks?
14 + 1 NA + 1 BA = 16
= 24 – 2 = 14
1 1 1 1 0 0 0 0 = 240
(C = 255.255.255.240)
11. A company is using a Class B IP addressing scheme and expects to need as many as
100 networks. What is the correct subnet mask to use with the network configuration?
(C = 255.255.254.0 and E = 255.255.255.128)
12. Given a host with the IP addressing 172.32.65.13 and a default subnet ,ask, to which
network does the host belong?
( C = 172.32.0.0)
13. What is the subnetwork number of a host with an IP addressing of 172.16.210.0/22?
IP = 172.16.210.0 =>1 1 0 1 0 0 1 0
SM = 255.255.252.0 =>1 1 1 1 1 1 0 0 1 1 0 1 0 0 0 0 = 128 + 64 + 16 = 208
(C = 172.16.208.0)
14. Which of the following IP addresses full into the CIDR block of 115.64.4.0/22? (choose three)
(B = 115.64.7.64, C =115.64.6.255, E = 115.64.5.128)
15. what is the subnetwork address for a host with the IP address 200.10.5.68/28?
IP = 200.10.5.68 => 0 1 0 0 1 1 0 0
SM=255.255.255.240 => 1 1 1 1 0 0 0 0 NA 0 1 0 0 0 0 0 0 =64
(C = 200.10.5.64)
16. The network address of 172.16.0.0/19 provides how many subnets and host?
IP = 172.16.0.0 => 0 0 0 0 0 0 0 0
SM= 255.255.224.0 => 1 1 1 0 0 0 0 0∑net = 23 = 8 net
∑host = 213 – 2 = 8192 – 2 = 8190 host
( F = 8 subnetts, 8190 hosts each)

(172.16.112.0)
23. Refer to the exhibit. The internetwork in the exhibit has been assigned the IP address 172.20.0.0. What would be the appropriate subnet mask to maximize the number of networks available for the future?
(A = 255.255.224.0)
24. You have a network with a subnet of 172.16.17.0/22. Which are valid host addresses?
/22 = 1 1 1 1 1 1 0 0 2 => kelipatan : 0 2 4 8 10 12 14 16 18
NA = 16
BA = 18
Sm = 252
(A = 172.16.18.255 255.255.252.0)

SM = 255.255.240.0 1 1 1 1 0 0 0 0 => ∑host = 213 – 2=4094
(C = 4094)
27. You have a Class B Network ID and need about 450 IP addresses per subenet. What is the best mask for this network ?
450 + 1NA + 1BA = 452
= 29 – 2 = 510 => sisa=58
