Expert Solution

Hi, I would like to answer you with these questions , I hope you will get something new to learn and if so then please give the thums up to the answer and not wasting much time lets head towards the answers:

Decimal to Binary

111 - 1101111
66 - 111110
252 - 11111100
11 - 1011
20 - 10100

Divide the number by 2 and you need to line up the remainder to get its binary

Binary to Decimal

00110110 - 54
11111000 - 248
00000111 - 7
10101010 - 170

The binary number is calculated as first digit is 2⁰ then increasing 0 to 1 then 2 and so on and calculte the sum at last like in 00000111 2⁰+2¹+2² = 1+2+4 = 7

Default Subnet Masks and their CIDR

Class A - 255.0.0.0 /8
Class B - 255.255.0.0 /16
Class C - 255.255.255.0 /24

The information which is used is that the 255 used block contains the network bits in the ip address rest with zero are host bit so Class A is like : 11111111:00000000:00000000:00000000 (N:H:H:H)

Identify the class of ip address

6.0.0.0 - Class A
120.0.0.0 - Class A
130.0.0.0 - Class B
199.100.1.0 - Class C

Ranges of ip addresses are as - Class A 0-127 ( face value ) Class B 128-191 Class C 192-223 After this there are for different other aspects Class D and E research and government uses.

So this was the explanation with the answers, Please give thums up to the answer and do comment for any queries

Thanks and Happy to help :)

HAPPY LEARNING

Converting from Decimal to Binary The algorithm you will use in this assignment to convert from base 10 to base 2 is: If the decimal number is zero, then the binary value is "0" Otherwise, start with an empty String to contain your binary value While your decimal number is not zero Get the remainder of what your current decimal number would be when divided by 2. Prepend this result to the front of your String. Divide your decimal number...
