Given the range of addresses he's looking to calculate, that would only be half correct.
The initial address range is, indeed, in the class B range. However, the fact that he only wants to go to 172.16.0.253 (realistically, he can't stop there, though, so would have to go to 254) indicates a class C netmask of 255.255.255.0, or /24.
