132.16.9.0 is which class of IPv4 address?

Explanation:
IPv4 addresses are grouped into classes by the value of the first octet. Class A uses 1–126, Class B uses 128–191, Class C uses 192–223, and Class D uses 224–239. The first octet of 132.16.9.0 is 132, which falls in the 128–191 range, so it is a Class B address. In the classic classful scheme, the default subnet mask is 255.255.0.0, meaning the network portion is the first two octets (132.16) and the host portion is the last two (9.0).
