You notice a printer on your network has the IP address 198.75.12.34 and subnet mask 255.255.255.248. What is the network address to which this printer belongs?

IP ADDRESS 198.75.12.34 11000110.01001011.00001100.00100010
SUBNET MASK 255.255.255.248 11111111.11111111.11111111.11111000
NETWORK ADDRESS(AND) IP AND NETWORK 11000110.01001011.00001100.00100000
= 198.75.12.32 ANSWER

A router interface on one of your subnets has the IP address 54.187.69.45 and prefix length /25. What would be the broadcast address used for this subnet?

Given:

IP address 54.187.69.45

prefix length /25 is class C

therefore network mask: 255.255.255.128

Now,

IP address 54.187.69.45 in binary 00110110. 10111011.01000101.00101101

network mask: 255.255.255.128 in binary 11111111.11111111.11111111.10000000

Host bit mask            : 00000000 00000000 00000000 01111111

To calculate Broadcast address OR Ip address and host

IP 00110110. 10111011.01000101.00101101
Host 00000000.00000000.00000000.01111111
Broadcast 00110110.10111011.01000101.01111111 = 54.187.69.127

This is an exercise in subnetting. You will compute a subnet mask and the IP numbers in each subnet. 1) assume you received a class-C IP address (221.221.221.0) and you are setting up a network with 4 subnets, each with 50 workstations. 2) use the IP Calculator ( http://bitcricket-ip-calculator.software.informer.com)  and compute the subnet mask and also check, and report, the maximum number of workstations in a subnet to see if you can have 50 workstations in each subnet. 3) obtain the...
