You’ll need to provide two valid forms of TCP/IP

Which of these would be considered a valid Class C address?

A) 191.168.77.2

B) 220.200.220.1

C) 10.44.100.8

D) 165.245.22.78

E) If it’s valid today, does it expire tomorrow?

The answer: B) 220.200.220.1

A Class C address starts with the bits 110x, which means the range of the first octet is between 192 and 223. If an IP address starts with any number between 192 and 223, then it’s a Class C address.
