Question
Consider a block of IP Addresses ranging from 100.1.2.32 to 100.1.2.47.Is it a CIDR block?If yes, give the CIDR representation.
Solution
To determine if the given block of IP addresses is a CIDR block, we need to check if the range of addresses can be represented using CIDR notation.
Step 1: Find the common prefix of the IP addresses in the block. The common prefix of the given IP addresses is "100.1.2".
Step 2: Determine the number of bits required to represent the range. To represent the range from 100.1.2.32 to 100.1.2.47, we need 4 bits (2^4 = 16) as the range includes 16 addresses.
Step 3: Check if the number of bits required is a power of 2. Since 4 is a power of 2, we can represent the range using CIDR notation.
Step 4: Write the CIDR representation. The CIDR representation of the given block of IP addresses is 100.1.2.32/28.
