Which class does the network 123.23.23.23 belongs to?
choose the best option
- Class A
- Class B
- Class C
- Class D
- its invalid IP address
Explanation
In the context of IPv4, IP addresses are divided into five classes: A, B, C, D, and E. Each class is defined by a specific range of values for the first octet of the address, as follows:
- Class A: addresses that start with a first octet ranging from 1 to 126 (e.g., 123.23.23.23)
- Class B: addresses that start with a first octet ranging from 128 to 191 (e.g., 140.190.23.23)
- Class C: addresses that start with a first octet ranging from 192 to 223 (e.g., 192.168.23.23)
- Class D: addresses that start with a first octet ranging from 224 to 239 (e.g., 224.0.0.0)
- Class E: addresses that start with a first octet ranging from 240 to 255 (e.g., 240.0.0.0)
Class A addresses are typically used for large networks, and they can accommodate up to 16 million hosts. Class B addresses are typically used for medium-sized networks, and they can accommodate up to 65,000 hosts.
Class C addresses are typically used for small networks, and they can accommodate up to 254 hosts. Class D addresses are used for multicast addresses, and Class E addresses are reserved for experimental use.
Therefore, the correct answer is: Class A
