Answer #1

5.

C2FA8DF1 in hexadecimal = 194.250.141.241 in decimal = 11000010.11111010.10001101.11110001 in binary

It is within the range of 192.0.0.x – 223.255.255.x, i.e under class C.

Net id :: 00010.11111010.10001101

Host id:: 11110001


6.


983E2B4F in hexidecimal = 152.62.43.79 in decimal = 10011000.00111110.00101011.01001111 in binary

IP addresses belonging to class B ranges from 128.0.x.x – 191.255.x.x. So it is in class B

Net id:: 011000.00111110

Host id:: 00101011.01001111


7.

BED2F537 in hexadecimal = 190.210.245.55 in decimal = 10111110.11010010.11110101.00110111 in binary

IP addresses belonging to class B ranges from 128.0.x.x – 191.255.x.x.. So it is in class BED2F537

Net id :: 111110.11010010

Host id :: 11110101.00110111

8.

C53FF321 in hexadecimal = 197.63.243.33 in decimal = 11000101.00111111.11110011.00100001 in binary

IP addresses belonging to class C ranges from 192.0.0.x – 223.255.255.x. So it is in class C2FA8DF1

Net id:: 00101.00111111.11110011

Host id:: 00100001

9.

6B6DFABC in hexadecimal = 107.109.250.188 in decimal = 01101011.01101101.11111010.10111100 in binary

This belongs to class A.

Net id : 1101011

Host id :: 01101101.11111010.10111100

    Find the network address, the broadcast address, and the range of host addresses for each given IPv4 address. The network address is calculated by setting all host bits to zero. The broadcast address is calculated by setting all host bits to one. The available addresses to assign to hosts on the network are the addresses between the network address and the broadcast address. The CIDR (Classless Inter-Domain Routing) number indicates the number of network bits. Since IPv4 is a 32-bit...
