In old-style classful subnetting, what class would be associated with the IP address 18.104.22.168?
A) Class A
B) Class B
C) Class C
D) Class D
E) Schools out for summer!
The answer: B) Class B
The now-antiquated classful subnetting associated specific subnet masks to ranges of IP addresses. The Class B subnet consisted of ranges where the leading bits of the first octet were 10xx. Therefore, the digital representation of this octet consists of IP addresses where the first octet ranges between 128 through 191.
