1. Determine network information for a given IP address and network mask.

Task 2: Challenge

Problem 1:

Host IP Address: 172.30.1.33Network Mask: 255.255.0.0

To change these decimal number to binary number is by following these step:-

1) Convert Host IP Address to Binary172.30.1.33

From these number, what can we added to get the total 172.30.1.33 ?

20= 1

21= 2

22= 4

23= 8

24= 16

25= 32

128+32+16+4=172

So the number will be 10110100 and this number is a binary number for 172 .

Network Broadcast Address is 172.17.255.255

By counting the number of host bits, we can determine the total number of usable host for thisnetwork.

Host Bits: 16 (count the inverted Number)

Total of number Host:

216=65536

65536 2 = 65534 (addresses that cannot use the all 0saddress, network address, or the all 1s address, broadcastaddress.)

Problem 5:

Host IP Address: 192.168.3.219

Network Mask: 255.255.0.0

To change these decimal number to binary number is by following these step:-

1) Convert Host IP Address to Binary192.168.3.219

From these number, what can we added to get the total 192.168.3.219 ?
