Show Suggested Answer

Suggested Answer: B

RFC 1918 defines private IP address ranges for use within private networks. The address space 172.16.0.0 to 172.31.255.255 is designated as private and falls under class B.

Class B Address Space: The range 172.16.0.0 to 172.31.255.255 is a private IP address range designated for class B networks.

Subnet Mask: A subnet mask of 255.255.0.0 (/16) is commonly used within this range to create subnets.

I'm not sure, but I think it might be class C because the subnet mask 255.255.0.0 corresponds to a class C address range.

Class B, definitely. I remember learning that RFC 1918 reserved the 172.16.0.0/16 block for private networks.
