The IP Address 172.168.10.1 belongs to which class?

The IP address 172.168.10.1 belongs to Class B. To understand the classification of IP addresses, it's important to look at the first octet of the IP address and the range that it falls into.

Class B IP addresses are those that start with a first octet in the range from 128 to 191. The first octet of the given IP address is 172, which falls within this range. This indicates that 172.168.10.1 is indeed a Class B address.

Class A addresses start from 1 to 126, which is outside the range for the given IP address. Class C addresses start from 192 to 223, which also doesn't fit. Class D is used for multicast addresses, starting from 224 to 239, and does not apply to standard IP addressing. Therefore, based on the analysis of the first octet, identifying the correct class of the IP address is pivotal, leading to the conclusion that it is indeed Class B.
