Given the CIDR representation 20.10.30.35 / 27. Find the range of IP Addresses in the CIDR block

To find the range of IP addresses in the CIDR block 20.10.30.35 / 27, we can follow these steps:

Step 1: Convert the IP address to binary representation. The IP address 20.10.30.35 can be converted to binary as follows: 20 -> 00010100 10 -> 00001010 30 -> 00011110 35 -> 00100011

So, the binary representation of the IP address is 00010100.00001010.00011110.00100011.

Step 2: Determine the network address. To determine the network address, we need to apply the subnet mask. In this case, the subnet mask is /27, which means the first 27 bits are set to 1 and the remaining bits are set to 0.

The subnet mask in binary is: 11111111.11111111.11111111.11100000

By applying the subnet mask to the IP address, we get the network address: 00010100.00001010.00011110.00100000

Converting this back to decimal, the network address is 20.10.30.32.

Step 3: Determine the broadcast address. The broadcast address is the highest address in the range of IP addresses. To find it, we need to set all the remaining bits after the subnet mask to 1.

The broadcast address in binary is: 00010100.00001010.00011110.00111111

Converting this back to decimal, the broadcast address is 20.10.30.63.

Step 4: Determine the range of IP addresses. The range of IP addresses is from the network address to the broadcast address.

So, the range of IP addresses in the CIDR block 20.10.30.35 / 27 is from 20.10.30.32 to 20.10.30.63.
