Question

Which of the addresses below are valid host addresses of the subnet to which the host 192.168.15.19/28 belongs?

Answer 1

Which of the addresses below are valid host addresses of the subnet to which the host 192.168.15.19/28 belongs?

Explanation:

• 192.168.15.17
• 192.168.15.29

The network employs a 28-bit subnet (255.255.255.240). 4 bits are employed for network and 4 bits are employed for the hosts. Thus it allows for 14 networks and 14 hosts (2n-2).The last bit is used to make 240 and it is the 4th bit (16) thus the first network will become 192.168.15.16. The network will have 16 addresses .(Note: that the first address is the network address and the last address is the broadcast address). The networks will increase incrementally by 16 beginning at the address 192.168.15.16/28. The IP address we are provided above is 192.168.15.19. Thus the rest of the host addresses ought also to be on this network. The Valid IP addresses for  the hosts  found on this network are: 192.168.15.17 and 192.168.15.30.
